I am currently working on a server control for other applications in our company to interface with a WCF service. Every time I make a change code change and recompile the control, I increment the the AssemblyVerison and AssemblyFileVersion class in the AsseemblyInfo.cs by one. For example, my latest build went from 1.0.07.0 to 1.0.08.0.
When the consuming application updates the file by copying the latest file in the bin directory and tries to compile, they receive the following error:
The type or namespace name 'MyControl'
does not exist in the namespace
'MyNamespace' (are you missing an
assembly reference?)
In order to resolve this error, they have to delete the current reference and re-add the reference.
Is there any way to update the server control without having to delete and re-add the reference?
I am not strong naming the server control.
#JPunyon - Do you mean have the consuming application add the server control project to their solution?
In my case it was a project defined using Target Framework: ".NET Framework 4.0 Client Profile " that tried to reference dll projects defined using Target Framework: ".NET Framework 4.0".
Once I changed the project settings to use Target Framework: ".NET Framework 4.0" everything was built nicely.
Right Click the project->Properties->Application->Target Framework
Right-click the assembly reference in the solution explorer, properties, disable the "Specific Version" option.
If none of the solutions above worked, try this 10-second fix.
Navigate to the startup project in solution explorer. Right click, properties > Application > Target framework. Change the target framework to anything else. Press Yes for the confirmation dialog. Give the changes a few seconds to take effect, then switch the framework back to what it was before.
The error will hopefully go away for you like it did for me!
Are you strong-naming your assemblies? In that case it is not a good idea to auto-increment your build number because with every new build number you will also have to update all your references.
I bumped the answer that pointed me in the right direction, but...
For those who are using Visual C++:
If you need to turn off auto-increment of the version, you can change this value in the "AssemblyInfo.cpp" file (all CLR projects have one). Give it a real version number without the asterisk and it will work the way you want it to.
Just don't forget to implement your own version-control on your assembly!
If the code is working previously and is throwing errors now, as mentioned in the above answers one of the config could have been modified. In brute force approach, close the VS editor and delete .vs folder in the same directory of the .sln file. All the config will be cleared and picked up from the repo files.
In my case, I had to change the Copy Local setting to true (right-click assembly in solution explorer, select properties, locate and change value of Copy Local property). Once this setting was changed, publication of my WCF service copied the file to the server and the error went away.
I encountered this error with an Azure DevOps Services (MS-hosted) build pipeline on a TFVC repo.
In my case, I was working within a branch and had accidentally added the reference from the package folder in trunk instead of from the branch. Once I added the reference from within the branch, it started compiling successfully.
I.e., while working on \branch-beta\sierra.csproj, I accidentally referenced \trunk\packages\delta.dll. Obviously, I needed to reference \branch-beta\packages\delta.dll instead. The mixup occurred because the path is not prominently displayed in the Add Reference window and I didn’t check carefully enough.
I found this issue in Visual Studio 2019 Version 16.4.4
I resolved most issues by discovering that the
packages.config
was missing the appropriate reference
eg:
<package id="System.Runtime" version="4.3.0" targetFramework="net461" />
Delete 'Web.Debug.config' and 'Web.Release.config' file for your solution directory,it should remove all errors
While creating new Blank UWP project in Visual Studio 2017 Community, this error came up:
After restoring the NuGet cache the reference resurfaced in the Project.

I have an ASP.NET MVC 4 app developed in VS 2012. The app consists of a main project (MyProject), a unit-test project (MyProject.Tests), an Azure deployment project (MyProject.Azure), and a couple of general-purpose library projects.
When I right-click on either the solution or the main project and select Manage NuGet Packages, I see a bunch of Microsoft updates that have apparently become available in the last month or so. If I click on the Update All button then the updates are apparently installed without any obvious problems, but when I build the solution I get this error message TWICE:
warning : All projects referencing MyProject.csproj must install nuget package Microsoft.Bcl.Build
Ok, so I have two projects that reference MyProject: MyProject.Tests and MyProject.Azure. I can right-click MyProject.Tests, select ManageNuGet Packages, and add Microsoft.Bcl.Build. That gets rid of one of the two warnings. But VS does not give me an option to manage NuGet packages for the MyProject.Azure project.
How do I add the Microsoft.Bcl.Build package to the Azure deployment project?
EDIT:
Thanks to user swell, I now know that a Microsoft Connect issue for this problem has been opened here.
The answer provided by TheESJ is correct, however the wording wasn't clear to me. Since I cannot comment on the answer, I will provide more details here. Specifically, I was having this problem with an Azure project and the following workaround was required to make the warning go away:
When you double-click the warning in VisualStudio, you will be taken to the BclBuildValidateNugetPackageReferences target in the Microsoft.BclBuild.targets file. Above the actual target element, you should find a large comment block that talks about disabling the project reference checks. Since Azure projects cannot have any library references, it is impossible for those Azure projects to fulfill the requirements of this particular build target.
The solution? Disable reference checking from the Azure project since it is impossible to actually add a nuget package reference.
EXAMPLE
So, assume we have two projects: MyAzureProject.ccproj which references MyProject.csproj. Follow these steps:
Right-click on "MyAzureProject" in the Solution Explorer and select "Edit Project File."
Find the project reference to "MyProject." It should look something like:
<ProjectReference Include="..\MyProject\MyProject.csproj">
<Name>MyProject</Name>
<Project>{1d99490e-d140-4897-9890-238e673a5864}</Project>
...
</ProjectReference>
Add the following element inside of the ProjectReference element:
<Properties>SkipValidatePackageReferences=true</Properties>
Your project reference should now look like this:
<ProjectReference Include="..\MyProject\MyProject.csproj">
<Name>MyProject</Name>
<Project>{1d99490e-d140-4897-9890-238e673a5864}</Project>
...
<Properties>SkipValidatePackageReferences=true</Properties>
</ProjectReference>
Right-click on "MyAzureProject" in Solution Explorer and choose "Reload Project."
You should now be able to rebuild and the error should be gone.
If you double click the warning it gives you instructions for disabling the warning.
It is safe to disable for projectreferences from projects that don't yet support Nuget.
See below portion in bold copied from Microsoft.Bcl.Build.targets.
BclBuildValidateNugetPackageReferences
This target can be disabled for a project reference by setting SkipValidatePackageReferences=true for the reference:
<ProjectReference Include="..\pcl\pcl.csproj">
<Project>{664a9e98-fac7-4567-a046-0dde95fddb48}</Project>
<Name>pcl</Name>
<Properties>SkipValidatePackageReferences=true</Properties>
</ProjectReference>
I faced the same issue and was trying to update Microsoft.Bcl.Build.targets; which did not help.
After some investigation found that .csproj file of the Azure Service project must be modified to include <Properties>SkipValidatePackageReferences=true</Properties>.
This was not apparent from the answer of #TheESJ and so decided to post separate answer. Thanks to #TheESJ.
I encountered this issue a number of times, and the Properties method does indeed work, but when dealing with a Wix project, I had to do the following instead:
<AdditionalProperties>SkipValidatePackageReferences=true</AdditionalProperties>
When I used the Properties Xml node, I got a new error:
The OutputPath property is not set for project
'MyInstallerProject.csproj'. Please check to make sure that you
have specified a valid combination of Configuration and Platform for
this project. Configuration='Debug' Platform='x86'. This error may
also appear if some other project is trying to follow a
project-to-project reference to this project, this project has been
unloaded or is not included in the solution, and the referencing
project does not build using the same or an equivalent Configuration
or Platform.
After failing to resolve the issues with any of the above answers, I simply followed the instructions contained within the Microsoft.Bcl.Build.targets file (displayed after double clicking on the error in the build output window).
I unloaded my project (referencing Azure packages), encountering the error. Edited the project file and inserted the following...
<PropertyGroup>
<SkipValidatePackageReferences>true</SkipValidatePackageReferences>
</PropertyGroup>
...at the top of the project file before the first PropertyGroup.
First off, let me start by saying that Nuget is awesome. I love it. That being said, there is one thing about it that I have just discovered which is really getting very annoying.
We have an in-house framework which we use for almost all of our projects. So, I recently created a Visual Studio project template for it, along with the VSIX.. had a few problems along the way due to Nuget.. it wouldn't create the new project from a template when the template was referencing the framework.. because the framework was using Nuget and it couldn't find the nuget folders in the new project created from the template. So, solution was to remove nuget from the framework project and only use Nuget for the other projects (anything but the framework). Okay, great.. that solves the problem!
However, now with every Nuget managed project that I open, it automatically adds these 2 lines back into the .csproj of the framework:
<RestorePackages>true</RestorePackages>
and
<Import Project="$(SolutionDir)\.nuget\nuget.targets" />
This is frustrating because we now need to either stop using Nuget altogether OR to keep removing these lines from our framework's .csproj file every time we want to rebuild the template.
Is there any way I can tell Nuget to ignore one project in the solution? In my case, to ignore the framework project...
With a suggestion from Nailuj and also from what I found here: http://samritchie.net/2012/09/17/nuget-packages-in-vs2012-templates/, I tried something that I thought would work, but it didn't serve my needs; that method is just for including the packages in with the new project, which for me is not helpful and doesn't solve the problem (error about missing .nuget targets folders). So, I played with it a bit and came up with something that is not ideal, but is acceptable:
Remove anything and everything to do with Nuget from the project which is to serve as a template. This then causes a problem with the referenced framework, because the framework project is expecting to be managed by Nuget and from this solution it's not, so error occurs... so:
Remove the framework project from the solution and only reference the DLL so it will build, but not complain about missing nuget folders
Rebuild
Export to template
Build VSIX using exported template
Install template
Create a new project from the newly installed template
Enable Nuget package restore on solution of new project
Open Package Manager Console
Notice message about missing packages and agree to download and install them (about 1 minute)
Remove framework DLL reference and replace with actual project (Right-click, Add Existing Project)
Rebuild and run
Celebrate!
I hope this helps anyone else who may find themselves in this predicament. If anyone has a better idea, please let me know. The bounty is still open for another 6 days, so I won't mark this as answer yet.
I am using Visual Studio Professional 2010 and the Team Foundation Server Express (beta). My VS Project (C#.Net / WPF) has been migrated from VS 2008 (without TFS) to VS 2010 (with TFS).
Whenever I apply changes to my code and try to debug my application, I get messages like This breakpoint will not be hit. (in german: Der Haltepunkt wird momentan nicht erreicht. Der Quellcode weist Unterschiede zur Originalversion auf.) and the project is started using the old executable version (the one with the last successful build). No errors occure, the code is OK, but the changes are not applied either.
When I manually cleanup and rebuild my project, everything works quite fine - but there has to be a fix for this issue?
Edit: I just added a new project to my VS solution and checked it in on the TFS Server. Using this new project the problem does not occure. Even when I add the same dependencies I used in the project mentioned above, the debugging and building of the new project works fine without the errors mentioned above.
Maybe this information helps you to lead me to a solution.
It's not clear whether existing answers are not sufficient. I can't know exactly what's causing your problem; but, I can detail some places this potentially comes up.
The first area that I commonly see this is when a project references an assembly directly. You can create a project that creates an assembly. Another project might use that assembly and you can reference by assembly directly (and not add a reference to the "project"). This disconnects VS from really knowing it needs to "build" that referenced assembly first and it will sometimes get out of sync with the debugging symbols (PDB). You can tell if a project has been referenced or an assembly has been referenced in the properties of the reference (expand References in Solution Explorer, right-click a reference, and select Properties). A referenced project will not have a Specific Version property, while an assembly reference will. You can sometimes also tell from Project\Project Dependencies. If you have a reference to an assembly generated by another project but that project isn't a dependency in Project Dependencies, it might be an assembly reference. To fix this, you can usually just delete the reference and add a reference to the project.
I've also find that sometimes breakpoints confuses the debugger. If I have many breakpoints or they've been kicking around a long time, the debugger sometimes does some weird things. If I delete all the existing break points (Debug/Delete all breakpoints) and re-apply them the debugger is usually much happier.
You can find the answer here. The assemblies might be in GAC or a project or some projects need to be rebuild to generate the pdb files again, which are used for debugging. If you don't choose to rebuild it might use the old pdb files.
My guess is that you are putting breaking points somewhere your program can't access them.
Ex:
const int x = 5;
if(this.x == 1)
//do sth <--- breakpoint here
If you are running a mixed mode application (unmanaged native C++ & managed C#), make sure to set Enable unmanaged code debugging in your C# application's Properties window.
You have to rebuild, there isn't an easier way around it.
The program database files (PDB) need to be recreated. You should also have your configuration setting set to debug.
Also the first answer to this question must be of help as well.
This happened to me when I started VS as an admin, and it also happened to me when the project is set to a different architecture than a DLL that I used in this project.
Why do I get the following error when building a setup project?
An error occurred while validating. HRESULT = '80004005'
One project in solution had ToolsVersion="4.0" (in .csproj file), changed it to ToolsVersion="3.5" and setup project builds fine.
Both of the reasons I found are already in other answers, but they are in separate answers and not fully explained. So, hopefully this will combine the possibilities and give good means of debugging each. :)
Common Reason
My problem was not a dependency error. However, that does seem to be the common reason. So, basically, you need to check your MSI file and make sure that all dependencies are still valid. Probably the best blog response on how you can easily resolve this if it is a dependency issue is An error occurred while validating. HRESULT = '80004005'.
Extract from blog:
Follow steps below to troubleshoot.
If you have multiple project outputs in your solution, identify the project that is giving the problem. You can do that by removing one project at a time from the Setup Project(S) until error goes away.
Once project is identified, identify the reference that could be giving the problem.
Check if the project(A) is referencing to a project that has been removed from solution. - Remove such references if any.
Check if the Project(A) is referencing to a project that was moved to a diffenrent physical location after it was added as a reference. - Remove and add such references.
Rebuild setup project after fixing the reference accordingly to see if error goes away.
Alternative Reason
My problem had to do with Visual Studio versioning, however. So, if your dependencies are valid and you still are getting this problem, then you resolve this if it is a problem with VS2010 .
Basically, if you run MSBuild and see this warning:
Project file contains ToolsVersion="4.0", which is not supported by
this version of MSBuild. Treating the project as if it had
ToolsVersion="3.5"
Then the problem is Visual Studio versioning. This means that one project was opened or created in Visual Studio 2010 and then saved or added to an existing 3.5 solution. I simply searched all files in my project for ToolsVersion="4.0" and found the offending .csproj file, opened it in a text editor and manually changed the 4.0 to a 3.5.
This error is related to a dependency error. I removed all references to my primary output project and added them again. It now compiles OK!
I ran up against this issue today. The solution in my case? Restart Visual Studio 2008.
In my case my solution (VS2008) had a project that was also referenced from another solution (VS2010). In the VS2010 solution I had upgraded the project to .NET 4.0. When I later realized the project was also used in another solution I downgraded it to .NET 3.5. For some reason everything seemed to be changed correctly in the csproj file except one place which is mentioned here: Error in setup project HRESULT = '80004005'
I know this is already solved somewhere else but I wanted to shed some light on this from another problem angle.
While simply removing and re-adding the project dependencies will work in many cases, it is important to note that:
The error message "An error occurred while validating. HRESULT=80004005."
usually happens when project is referenced to the other project which is
not added into the currect [sic] solution. Setup project only supports
dependency projects within same solution.1
I have spent enormous time on this one myself, though none of the above worked. But I have found another solution with a registry hack, you need to add a new DWORD (EnableOutOfProcBuild) value of (0) to HKCU\SOFTWARE\Microsoft\VisualStudio\14.0_Config\MSBuild\EnableOutOfProcBuild
Note: this is for Visual Studio 2015
In my case I had installed Visual Studio 2010 alongside Visual Studio 2008. My setup project, when opened in Visual Studio 2008 gave the same error, but was OK in Visual Studio 2010.
If copied to another machine that did not have Visual Studio 2010, but did have Visual Studio 2008, then it would compile.
I installed Visual Studio 2010 and converted the solutions to that version. Because of performance issues I changed my solutions back to Visual Studio 2008. Everything was better now but I got an error when I tried to compile the setup project. I realized that I had a Visual Studio 2010 Test Project in my solution so all I had to do was unload the Test Project and Build the setup project again.
Summary: unload any Visual Studio 2010 project in solution.
I hope it helps.
I know this is kinda old news, but my particular issue and solution are not specifically stated here (as far as I can tell - if I missed it, I apologize).
I had same problem. It would not compile my project, but had no errors. All I could see was "Build Failed". I opened up the "Output" file (Click View--> Output on menu), and it told me exactly which reference (in my case a .dll) was causing the problem.
I deleted and recreated the reference and it changed the reference name from Microsoft.Office.Core (which was appearently only a 32 bit version) to "OFFICE". Then everything worked great. -- Make sure to make a note of the path to the file you are referencing in the properties window... My new path was exactly the same, but the reference name changed anyway.... still scratching my head on that one...
So the moral of the story is... When you get no errors and your build fails, check the "Output" tab and it might help.
I read this answer from another post on Stack Overflow, and it has worked for me.
Open your setup project file (.vdproj) in Notepad (or any other text editor). Delete these lines at a beginning of the .vdproj file:
"SccProjectName" = "8:"
"SccLocalPath" = "8:"
"SccAuxPath" = "8:"
"SccProvider" = "8:"
Build again - the error is gone. That error didn't stop me from deploying, building, debugging (or anyting) my project; it just annoyed me. And it came on even if I set all projects to be build in a current configuration and the setup project not to.
Issue: Just started today, all references to any assembly outside of the solution fail to resolve, with The referenced component 'SomeComponent' could not be found. when trying to build. This happens for both 3rd party components (all 15 or so of them) as well as all .NET Framework assemblies - basically anything that isn't another project in the same solution.
Trying to load some other solutions produced the same issue. Creating a new WinForms project worked without a problem, however. (Scratch that, it worked before reinstalling VS, now that doesn't work either. I created a new WinForms app as well as a WPF app, and the designer can't load the assemblies either. I tried targetting 3.5 and 2.0 and no luck.)
Things I've tried:
Repair Visual Studio installation
Rebooting computer
Started VS with /resetsettings flag
System Restore to 2 days ago when it was known to be working
Uninstalling VS and reinstalling
Fresh checkout from SVN
Does anyone have any experience with this and know of a way to get this working again? My strongest Google-fu has failed me, so I'm asking here. Can mark community wiki if requested.
Update:
I tried "upgrading" Windows (to the same version) since I didn't see a repair option for Vista and it's still a no-go. I reinstalled everything that seemed relevant. So far, it's looking like I'm just gonna have to back up and reformat I guess unless a solution comes up sometime before tomorrow.
Update2:
I just backed up data and reformatted, so I'm no longer able to verify any ideas that I haven't tried yet, so I'll just leave the bounty to expire on its own to the top voted answer and as a reference to anyone else who may have this problem later.
I had the same problem. It turns out that something was wrong with NuGet. I removed the following part of the *.csproj-File (opened in a text editor). This has solved the issue for me:
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
<PropertyGroup>
<ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
</PropertyGroup>
<Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
</Target>
In my case, the solution was completely different. It looked like it was an issue with NuGet paths (caused by my moving the project to a different solution and then back again.
I edited the .csproj and removed all references to NuGet and associated packages. I also removed the packages folder from the solution folder.
The system components then magically reappeared.
Suggested next debug step: review Project Designer: References -> Reference Paths to verify that the paths to your system and third-party components appear correctly. (Watch out for things that can slip past the old Mark I Eyeball like drive letters.)
Try running VS after turing on Assembly load logging with fuslogvw. You'll be able to see additional errors captured by the runtime when it tries to locate and load the assemblies.
In Vista, you'll have to run fuslogvw as an administrator and somtimes specify an explicit path to save the logs.
You can also try debugging Visual Studio by attaching to it from another instance, or with the basic debugger included with the .NET SDK.
I had this similar issue not too long ago.
I found that the issue was caused by git not properly creating .exe's when jumping from branch to branch(we have nuget.exe in a path and it was getting deleted/added when jumping branches). When you would try to run nuget, windows would throw a fit over the exe.
After reseting the branch many times, I finaly got the exe to run properly. Then I noticed that the security on all the directories in the repo had been reset, so I had to deal with that.
After all of that, visual studio then started to play nice.
Hoped this helps someone!
It may also be a problem with references of other projects in the same solution. I only wanted to build one project, but got this message about references in another project. Although the problem in the other project was correct, I think the message was not correct:
I did not expect the message about another project (the other project was no dependency, so it did not 'need' to be built)
I could not 'interpret' it, because it did not mention the project it was about).
Well, if you click on the error, in VS 2012 RC, and then debug it, the error is gone...
I know that this is an old question but it is still happening in the latest version of Visual Studio (2015). I fixed it in a different way that might not have been available back when the question was asked. Basically, it is related to the fact that VS can't find the .Net Library package. To fix in the latest version of Visual Studio (2015):
Right Click on your solution in the Solution Manager. Choose "Manage NuGet Packages for Solution..."
in the NuGet Window, go to "Installed".
If you have something related to Microsoft.Net such as "Microsoft.NetCore.UniversalWindowsPlatform", remember the name and uninstall the package.
Now go to the browse tab and find the package and install it again. Don't forget to select the correct needed project.
Everything should be ok now.
I hope this helps somebody!
I hate to say it, but it sounds like the system is pretty borked. There has to be a point when it is quicker to reinstall the OS than it is to continue trying to fix the current install.
I just hope you take this in the right spirit... sorry.
Shot in the dark here, but I've run into the same (similar) problem. The issue I ran into was related to having a 64bit machine and running a project that had a mixture of 64bit and 32bit 3rd party dll's. The solution was to ensure I had the correct bits (32v64) and then to have the project build in 32 bit mode: project properties > build > platform target: x86.
Another time this occurred I had to remove all the 64bit dll's and reinstall with the 32bit dll's
HTH's
.nuget folder was missing. add the .nuget folder with nuget files (usually 3 files). open the solution and no warnings on references. My submodule has nuget references and when I pulled the latest version, the solution needs .nuget folder in the project folder.
i.e.
project
/.nuget
/submodule
/.nuget
Visual Studio was unable to find any of my references.
What i did, and following some solutions above, was:
Right click solution entry in Solution Manager window;
In the newly opened NuGet window go to installed, select all entries and update.
The problem gets solved!
Check your output with ILDASM to make sure the references are showing up correctly -- compare them to an assembly that works, and see if anything jumps out at you.
I once encountered a problem, which is in the *.csproj file. It defines an Error node in the Target node, that if one reference/nuget-library doesn't exist, it throws the error while building. The problem is VS do not show correct status for other libraries, thus all the referenced libraries looks like non-loaded, that the local file path cannot be found in the property window.
Here is a sample.
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
<PropertyGroup>
<ErrorText>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them. xxx.</ErrorText>
</PropertyGroup>
<Error Condition="!Exists('..\packages\...\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\...\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props'))" />
<Error Condition="!Exists('..\packages\NOT-Exist.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\NOT-Exist.targets'))" />
</Target>
...
