I am going to lose my mind. NuGet has decided that any attempt to update a package destroys my Solution. I am running Visual Studio 2013 Ultimate w/ Update 3. I have been working on this solution/application for over a year and had no troubles. This weekend NuGet started breaking my solution build every time I update a package, regardless of what package I update. Say, for example, I update AutoMapper. It tells me that it updates successfully but when I build it fails to find the assembly/reference. I then start having problems with all of the other NuGet Package references. I sometimes get errors that there are syntax errors with MsBuild, target framework version errors, etc. I have tried reinstalling Visual Studio 2013, uninstalling resharper, reinstalling resharper, clearing NuGet cache, Visual Studio 2013 component cache. I am out of ideas short of rebuilding my machine.
Any thoughts?
UPDATE: 09/02/2014
I tried this process on a brand new machine and I got a lot further. I still, however, do have the following problem with my build. This problem seems to happen on every machine.
Error 4 Invalid static method invocation syntax: "[MSBuild]::MakeRelative($(MSBuildProjectDirectory), C:...\Source\packages\AutoMapper.3.2.1\lib\net40\AutoMapper.Net4.dll)". Method '[MSBuild]::MakeRelative' not found. Static method invocation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(a, b)). ChoiceMentor.Presentation.Services
In this particular case, the answer was that a comma had been put into one of the file path folder names. This caused MSBuild to throw a huge fit. Renaming the folder fixed the issue. Thanks for the tips though everyone!

like title after upgrade, VS detect many error like this:
But the code build successfully.
I try to repair Visual Studio 2022 but this not solve the problem.
Any suggestions?
Thank you
This issue is caused not by the Visual Studio update from 17.2.5 to 17.2.6, but by the update from .NET SDK 6.0.301 to 6.0.302 (which is automatically done during the Visual Studio upgrade). Intellisense is still looking for the code analyzers in the old SDK directories.
To find this, you should actually not look at the errors, but at the warnings (seeing you have 56 warning, I guess you tend not to look at them. It's a very good habit to keep the number of warnings at 0).
Inbetween the warnings you should see something like:
Warning CS8034 Unable to load Analyzer assembly C:\Program Files\dotnet\sdk\6.0.301\Sdks\Microsoft.NET.Sdk\analyzers\Microsoft.CodeAnalysis.CSharp.NetAnalyzers.dll: Could not find a part of the path ‘C:\Program Files\dotnet\sdk\6.0.301\Sdks\Microsoft.NET.Sdk\analyzers\Microsoft.CodeAnalysis.CSharp.NetAnalyzers.dll’.
How I fixed it: by manually opening the properties (alt-enter) of each problematic project. If you do that, it automatically fixes the paths.
Hans Passant's fix (deleting all the obj directories) seems way simpler, and might be a good thing to do on any Visual Studio upgrade. (Note, only delete the build obj directories, not those of dependencies, like git/github/node-modules/etc)
edit: Note that there is a side-issue with .NET SDK 6.0.302, where source generators run twice, which breaks anything that relies on them, like the WPF- and WinUI community toolits.
edit2: Microsoft has notified that these issues should be solved with the next release/update.
Updating Microsoft.CodeAnalysis.Analyzers from the Package Manager Console removed the warnings for me.
NuGet\Install-Package Microsoft.CodeAnalysis.Analyzers -Version 3.3.3
See: https://www.nuget.org/packages/Microsoft.CodeAnalysis.Analyzers/#versions-body-tab
This morning I upgraded to VS 2017 15.3 and now am getting yellow triangles for most of my references. The project runs fine (build is good in CLI and VS and restore has been run multiple times) that I can tell (and even better on dotnetcore 2.0 actually) but these remain. Has anyone else had this happen or have a suggestion? Thanks.

Also issue of greyed out usings and red references although everything builds and runs fine.
Update: VisualStudio twitter account responded to me to note that this is a bug and they are working on a fix for the future on this....
I have two responses to my post:
1) The using issue noted with things greyed out was actually a ReSharper issue. If you upgrade to VS 2017 15.3 and use R# make sure you update it as well to 2017.2.
2) The Yellow triangles issue is being looked at by the Visual Studio team but honestly I believe it to be linked to warnings in the build that those references are being coerced to either lower dependencies (ie Newtonsoft at different levels) or previews. The quickly evolving .NET 2.0 world may have exacerbated this issue. Yellow triangles have traditionally meant missing but check your warnings to see if that is related and then review the dependency chain. I will update this answer once I hear back from VS team (shout out to them and Damian Edwards + Scott Hanselman for helping me with this on Twitter).
I was experiencing the yellow triangle on references issue after updating the projects in my (.NET 4.6.1) solution to the new .NET Standard .csproj format that comes with VS2017. The references I was getting warnings for were ProjectReference type (although it seemed to spill over into PackageReference for common packages in the projects in question).
I did not have any build warnings and there was nothing in the verbose build output to indicate what the cause could be.
I could follow all warnings back to a single project in my solution. I was able to solve by removing that project from my solution and then adding it back and re-adding only the necessary project references.
It seems the issue was related to unnecessary project references (or possibly circular) caused by the new transitive dependencies support. After removing the project and adding it back with only the minimum ProjectReferences and relying on transitive dependencies support to propagate the dependency, the warnings all disappeared.
This also solved an issue where the project in question was failing compilation during a command line msbuild initiated build on my CI server which only has VS2017 build tools installed (not the full IDE).
I had the same issue, some of the references were marked with the yellow triangle. However, I was able to build and run my project.
I managed to remove these warning by following steps from this answer:
.Net 2015 References with yellow triangle for Nuget packages on portable libraries
I turned on tracing for Visual Studio, I had next warnings in log files for all uncorrectly loaded references:
Encountered conflict between 'Reference:Microsoft.Win32.Primitives, Version=4.0.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL' and 'Reference:C:\Program Files (x86)\Visual Studio\MSBuild\Microsoft\Microsoft.NET.Build.Extensions\net461\ref\Microsoft.Win32.Primitives.dll'. Choosing 'Reference:C:\Program Files (x86)\Visual Studio\MSBuild\Microsoft\Microsoft.NET.Build.Extensions\net461\ref\Microsoft.Win32.Primitives.dll' because AssemblyVersion '4.0.3.0' is greater than '4.0.2.0'.
To be precise, I did next steps:
Removed error condition from my .csproj file
Removed <Private>true</Private> parameter for not-loaded references in .csproj file
Deleted not-loaded packages from \lib and \ref folders in corresponding MSBuild folder.
Deleted packages from \packages folder in solution.
Restored nuget packages.
I'm not sure all these steps are necessary, but it worked for me.
You could check my answer on relative topic here: https://stackoverflow.com/a/59704420/7969733
Just for documentation purpose for new person with this issue try
this and you will rememberme :D
If you go to: Tools > NuGet Administrator > Configurations. and you
have "Allow nuget...." and "automatically check...." cheked.
The only thing than you have to do is click con the button "Clear
All NuGet Cache(s)"
That's it, you don't have to edit manual thinks than can be dangerous,
believe me, I use to need to done some of the steps than describe here
a lot of time, and try more than 5 steps of the official Microsoft
documentation for that issue you could check it here:
https://learn.microsoft.com/nuget/consume-packages/package-restore#restore-packages-automatically-using-visual-studio
But just cleaning the cache solve all the problems

Mismatched Windows SDK Version between the referencing project and the references will cause it. In the vcxproj file it is "<WindowsTargetPlatformVersion>SDK Version</WindowsTargetPlatformVersion>"
I was upgrading from VS2012 to VS2017. Everything was good, then I upgraded to a new version of libtomcrypt and libtommath. Rather than tweak my existing projects, I up-converted the projects from the distributions from VS2008 -> VS2012 -> VS2017. In the process, I picked up Windows SDK Version 10.0.17763.0 in both the new projects. However, all of the projects that referenced those were 8.1, and thus the warning.
I know that this was ready to solve it, and one of my answers was ready to say something about that, but, maybe some of you present the same error and none of this solution listed here solves the problem... I don't know why this problem comes with the global installation of .net 6, but, if you present this issue again, you need to go to
C:\Users\YourUsername.nuget
And delete all the content, don't be afraid, that's a cache generator than will be created again if is need it.
I had a similar issue with visual studio 2017. And discovered that, if when I changed the dependency settings of the package I wanted to install (from lowest dependency to highest) everything worked fine.
Today faced the same issue with an imported project.
FAILED ATTEMPTS: Tried updating nougat packages, checking improper imports and everything imaginable. No help.
SOLUTION: At last just tried building the solution and it worked!
PS: Try building the project first. If it does not work then go for solution hunting.
I've had a problem with my Windows 7 after an update, neither Safe Mode nor Recovery Mode could resolve the problem. I was forced to reinstall Windows completely. To develop on my projects I need Visual Studio 2010.
I always had ReSharper installed and got used to its features, so I installed it aswell.
Everything setup I tried building my solution but encountered a problem ...
(The underlined file can be found here: https://up.zone/aj)
After hours of trying to resolve the problems, I figgured out that ReSharper was the problem. I can build the solution perfectly fine without ReSharper installed. Having it installed, even if all features are turned off and the services are suspended, causes these errors in the picture above to show on build.
I managed to resolve two out of three errors by following the instructions of this Reddit user on his post: https://up.zone/ag
Now I am left with one more exception I cannot figgure out how to resolve. I couldn't really find anything helpful googling, which means you guys are my last hope. I really do not want to go back to developing without ReSharper.
This is the one:
Any idea?
Thank you!
Update 1
I figgured out that the problem must be in the NuGet.targets file, located in the .nuget folder in our solution.
I managed to find a workaround following the suggestion of this post, I am now able to build the solution without any errors.
To summarize, remove this line out of your *.csproj file
<Import Project="$(SolutionDir)\.nuget\nuget.targets" />
Although this works, I don't think this can be the solution. This line is there for a reason I assume. Anybody with a deep understanding of NuGet who might know how to properly resolve this problem?
Update 2
I found out that as soon as you reload your solution/project, the line gets added once again. Also, if you have certain dependencies nuget should download for you - it won't, because the line which makes that call and handles this got removed.
I'm now at a point where I know where the problem is but not why it is caused.
Does ReSharper change anything in the way NuGet behaves? As far as I can tell, nothing gets added or removed to or from the NuGet.targets file due to ReSharper.
There were one more report on this topic, at https://youtrack.jetbrains.com/issue/RSRP-462271 .
The best guess so far is that this is caused by two things happening at once: (a) using MSBuild tasks in C# source code form inside MSBuild XML files rather than DLLs and (b) having some of the MSBuild opensource DLLs shipped with the latest version of ReSharper for its own project file handling needs.
The source code gets compiled into a task DLL during an MSBuild run (not a much common thing to have; Roslyn would do this rather than ship a DLL? seriously?). When building from within Visual Studio (rather than with msbuild.exe), the in-process MSBuild instance is used, and it would run in the same appdomain as ReSharper, so it uses the common assembly reference resoluiton. If it's not too accurate, then it might accidentally pick the wrong DLL version by the short name, which would break the task compilation (that's a separate error, maybe cached away) and then result in the task-not-found error later at runtime (SetEnvironmentVariable task not found in here case).
I've tested on sample solutions with source code based tasks and could not get it broken. So trivial cases are OK. Never heard back from the original issue reporter, so there was no further progress.
Now I've got a hint that this is Visual Studio 10 (any other VS versions installed on that machine?) and maaaaybe it's Roslyn tasks. We might know for sure if you run MSBuild with more detailed logs (by setting the logging options at Tools | Options | Projects and Solutions | Build and Run | MSBuild project build output verbosity to at least Detailed) and building just the faulty project.
I'll also try this out with VS10 and update this reply with new data.
We are currently evaluating the new Visual Studio 2015 and encountered a strange problem with IntelliSense. When I compiled our main solution with the new studio the build succeeds, but nevertheless 6 errors are shown.
I discovered that it's not a real error, but only an intellisense error. The code is definitely correct and everything compiled successfully. The code however is marked red and errors show up in the error list.
All 6 errors have the same origin. It's a simple constructor call. Strange enough, but there are also some occurrences of the exact same constructor without any errors.
The error message:
Code: CS1729
Message: '<the class>' does not contain a constructor that takes that many arguments.
Project: <the project name>
File: <the path to the file>
The new studio was installed on a freshly installed Windows 7 without any legacy software (no VS13).
I've already tried to clear the caches, deleted the suo file, deleted bin and obj directories, cleaned and rebuilt the solution etc. But nothing worked.
Can anyone explain that behavior to me?
I had thousands of intellisense errors and 0 build errors. After deleting .suo file and restarting VS intellisense errors are gone.
Suo file is located relatively to source in:
.vs\SolutionName\v14\.suo
According to comment: Beware that *.suo is a hidden file.
Edit: According to comments, VS2017 has the same issue, so you can use similar solution: Delete .vs\SolutionName\v15\.suo
VS2019 still has this issue. Delete .vs\SolutionName\v17\.suo
If deleting .suo still does solve your problem, then delete also all bin and obj directories in every project in the solution.
Also had this problem with a migrated project, so I referenced the Microsoft.CSharp dll. In some projects I needed to remove and add again the Reference in the project.
Ran into similar issue in Visual Studio 2017 ASP.Net Core Project. Following steps did the trick for me
Perform Clean Solution
Close VS
Delete .suo file & Delete bin/obj directories
Reopen VS
Similar problem as others, but different resolution. Posting in case I can help someone else.
Running Visual Studio 2017 15.5.2. I use Git and frequently switch branches. Several weeks ago, I started having editors show me errors (all related to types it could not find even though references were valid). Compile worked great. I confirmed the same issue in VS 2017 15.6 Preview (Jan 6, 2018). I would try to delete cache, SUO files, or bin/obj folders and no impact. At first it would appear to work. Reopen Visual Studio and everything would look good. Use "Rebuild Solution" and the IntelliSense errors would returns. I even tried uninstall/reinstall of Visual Studio.
I had the same issue on two machines, both with same version of Visual Studio.
By looking at the errors about missing types, they all appeared to come from two referenced projects. One of those references was a shared project used by just about every other project in the solution, but one of them was a small project without many references. It just so happens that the small project was also referenced by my larger shared project. In Visual Studio, I unloaded the small project and reloaded it. The errors went away! They errors did not come back on Rebuild Solution.
I then switched Git branches and the errors all came back. Fortunately I repeated the above steps of unloading/reloading the small project and the errors went away.
Every time I switch Git branches, the errors come back until I repeat that process. There are zero changes between the Git branches for the smaller project that I unload/reload. Unclear why that sequence is fixing my issue.
Also had this problem (the title, not the specific error message), as well as squiggly lines in the editor. The first squiggly line is under the first #include statement, which names a precompiled header. Intellisense fails to include the precompiled header, but doesn't list that as an error; instead it lists errors further down the file, on code that (very rightfully) relies on declarations in the precompiled header.
The reason Intellisense doesn't find the precompiled header in my environment is that the header named is not an actual file. It doesn't have to be in any other VC or gcc version I used, nor in the 2015 compiler, as long as the precompiled header settings are correctly configured. Apparently not any more for Intellisense. I'm not entirely sure it was different in 2013, maybe I just never noticed.
In the unlikely case that this would be the problem reported here, the solution is simple: create a small file with the pretend-name of the precompiled header, as specified in #include directives, and let that file include the actual name of the precompiled header.
If you wonder... why this distinction between the precompiled header name in the '#include' statement and the actual filename of the precompiled header? Precisely because it guarantees that precompiled header settings are correctly configured. Wherever a precompiled header is "#included", there is no file around that could be included. Either an actually precompiled (binary) version of the actual header is read, or the compilation fails. Obviously, a disadvantage is that it confuses people reading the code, not just Intellisense.
Visual Studio 2017
I have deleted ".suo" file from location .vs\SolutionName\v15.suo
And then restarted Visual studio. This worked for me.
Today I've had similar problem with MSVC++ 2015. I almost gave up and decided to go on without IDE hints, but suddenly I've noticed that stdafx.h of the project i had problems with doesn't contain any standard library headers. I've speculated that inclusion of all standard headers used in the project in stdafx.h might boost up compilation speed, however doing so fixed Intellisense errors as well.
In Visual Studio 2019 the problem is with changing branches with Git when there are NuGet packages installed in the project. What I did to solve this:
Clean Solution
Close Visual Studio
Delete the packages folder
Open Visual Studio
Go to Package Manager
Restore all packages
Recompile
If roslyn is missing, close and open Visual Studio, then recompile.
I had multiple stdfax.h in Additional Include Directories. Make sure the stdafx.h you intended is first in your path.
I had a similar issue with different Visual Studio versions.
Deleting the .suo or .vs folder did not help for me.
The Solution for me was, that I had the Extension StopOnFirstBuildError active. After turning off "Stop build on first error" in the build menu, and after the solution was fully built, the errors shown by Intellisense went away.
I was seeing the intellisearch errors only when publishing a website. (ASP/C# site, VS 2017). They broke the publish. Site ran fine locally.
Cleared the errors by unchecking the setting to pre-compile, and it published fine.
Publish -> Setting -> File Publish Options -> Precompile during publishing
I had this issue with a reference to another project. Removing and re-adding the project reference worked for me.
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.
