"The project file was unloaded" when moving VS2010 project to another server - visual-studio-2010

I have moved a Visual Studio 2010 project to another server by copying and pasting the folder contents into another folder on a different server.
My understand was that VS2010 handled this well; when I have done this locally it has never been an issue.
Now I get an error like this:
When I right click and "Reload project", the list of files briefly appears before disappearing again, giving the original error.
Am I doing something wrong?

I experienced the same problem today. Here is what I did and worked for me :
Open the .sln file.
Right click on the project folder and click Reload project.
You will see the projects and folders that you originally had.
You will see .xml publish file . Double click it .. You should be good to go now.

I had this problem today and it took me a while to figure out what was going on.
Your problem is most likely that your solution was originally made with a Visual Studio configuration that contained support for certain project types (such as "Windows Service" or some other exotic project type). The Visual Studio configuration you are using to import your solution does not have that support. In other words,
there is probably nothing wrong with your solution,
there is probably nothing wrong with your project,
there is probably nothing wrong with any of the files (as you mentioned they do display briefly, giving you a second of hope)
Just run the installer on the new Visual Studio and make sure the support is enabled for all the project types you need and try again.

In my case the problem was the .vbproj file had somehow been corrupted so the normal xml code was replaced with a long string of null characters. I noticed this thanks to a file that was generated in the same folder as the project file when I tried to open the project - it was called 'UpgradeLog.htm'. This had an entry saying ' Error on line 1. Expected '<' but found 'null character'.'.. suggests there may have been a recent update to Visual Studio that I hadn't noticed?
Luckily I could use my source control system to revert back to a slightly earlier version - I guess it shows how important it is to have backups!

In my case, I saw similar message (Projected was unloaded) and all I had to do was simply re-launching Visual Studio (2017) in Admin mode and the problem went away. Per one of the above answers, I tried to right-click and selected Reload but got a warning that, due to required access to IIS on the machine, I had to launch VS in Admin mode.

Found this answer and it worked for me.
Note:Sometimes, the path in File path property is grayed out and you are unable to get to the Browse button. In this case try deleting .suo files. Don’t worry, these files gets recreated when you rebuild the solution / project.

I had the same problem. I fix path to .csproj files in the .sln file with a text editor and now it is all ok.

Visual Studio not showing all Projects in solution

I'm not sure why, but Visual Studio is not showing all the projects in my solution. I need them to show so I can set as default project under solution explorer. I'm not seeing a fix for this issue in a general internet search. The closest I see is VS not showing files folders, but this is different than my issue. Hopefully there is an easy way to fix it, without adding things again piecemeal. My co-workers can see their complete set of projects in solution explorer so it must be a corruption in my workspace.
Open your ".sln" project file using Notepad.
In this file you can observe listed projects like below
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "test.myProject.Data", "test.myProject.Data\test.myProject.csproj", "{6D7F7B84-F3BD-4A19-A069-D144C345B887}"
EndProject
Please add if there any missing projects. If you have old back up or co-workers file, Just copy and paste missing projects to this file.
In my case it works !!
close vs , delete .vs folder then open vs again. it works for me.
I found that re-adding the existing project to the solution worked for me!
I had to copy out changed files in my workspace, fix my permissions/ownership on my directory (it was no owner instead of me), re-do the mapped drive the workspace was on, re-do the shortcut to the Visual Studio project (even though it was supposed to theoretically be the same place I mapped), re-pull the project down, and copy my changes in again. At this point Visual Studio had the missing solutions in it again so I could set startup project and run the debugger. I'm not sure how the ownership/permissions got messed up. I think at one point the other office had a server go down, and maybe my permissions/ownership got mixed up then. I'm not sure why VS wasn't showing the missing projects, but it's fixed after doing the above.
I had the same issue where my colleague saw 1 more project on his computer.
I deleted my .sln file and got the exact same version as he. Problem was still the same.
Solution was: I had an unloaded project. Apparently this is safed in a local user setting file (probably the .suo file). I looked for the unloaded project and loaded it again.
Close the VStudio entire project, go to the main project folder and click on the .sln file to load the entire project agian.
go to solution explorer see which are having (unload), right click and load project with dependencies
sometimes check if the project startup has changed, if changed just right click on the related project and set as project startup
This .sln file structure breakdown offers a great insight on how projects are able to be found and populated into the project hierarchy. My .sln file had lost all its project persistence blocks and thus I had 0 projects under my solution. I copied the blocks from a a previous git commit and this fixed it. I still don't know why the blocks disappeared or the whole .sln file changed
If the other solutions didn't work for you, then try this.
You can add the missing project to the solution file using the dotnet command. To do so, go to the root folder of your project and run the following command from the terminal:
dotnet sln add ProjectLibrary/ProjectLibrary.csproj
The ProjectLibrary/ProjectLibrary.csproj is the path to your missing project.
You can open the .sln file to confirm if the prject has been added. You should see something like:
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "ProjectLibrary", "ProjectLibrary\ProjectLibrary.csproj", "{F042B1DB-F887-44CC-941A-76569A86AF75}"
EndProject
Hope this helps.
I had the same issue. After opening the Visual Studio in Administrator mode it started to work.
Search for VS->Right click-> "Run as administrator"

The working directory does not exist in Visual Studio 2010

I am using Visual Studio 2010.
I wanted to study some code that dumps relevant data in a database, find out how it works and adapt it to my own version.
I only got as far as loading the solution in VS 2010, hitting the "Start Debugging" button, and then I got this error:
The working directory does not exist:
'D:\Dev\CodeProject\articles\smartcardfmwk\Smartcard_Framework
How can I fix this error?
The source code in question is Smart Card Framework, from Code Project
I downloaded the "Updated Project (VS2010)" and I can open it in VS2010, as well as build, but debugging just wouldn't work.
I did not try replicating the path yet, but as this is a working project, my company requires that it is placed on a very specific location accessible by others.
Nevermind, I got it. It was so simple, I'm sorry for wasting anyone's time.
The source Solution had a lot of Projects under them. I figured at least one of them was pointing to a directory that doesn't exist, so I waded through the Projects,
I right-clicked a Project and clicked the Properties
This will open up the ProjectName Property Tab
Under the Debug tab, there is a filed called "Working Directory"; I changed it to where the project is currently located.
This solved my problem, for now, unless there's a Project I missed. I am wondering, though, if I have to do this again if I move the Solution elsewhere.
This happened also in VS 2019 after importing / upgrading an old C# project. I was not able to see any project properties to change.
Finally it was fixed by manually editing the file <ProjName>.user.csproj as follows:
Replace
<StartWorkingDirectory>[wrong directory name]</StartWorkingDirectory>
with
<StartWorkingDirectory>.\</StartWorkingDirectory>
I also faced this problem that working directory does not exist, but I managed to solve it. There are certain steps to follow properly Whenever this error occurs.
In VS, open the "Project" at Toolbar.
Then go for Project properties.
Select Debug And check your working directory. If the path is wrong just browse it...

vcxproj file won't load into solution

We've just recently switched to VS 2010 and i had a solution that was working fine. This moring when i try to load the solution i get the error:
"An item with the same key has already been added."
This occurs when it is trying to load one of our main projects and it is not loaded.
I assumed the problem was with my solution so i created a brand new empty solution and tried to load the same vcxproj and got exactly the same error.
When i revert the project file to a previous version it works, so apparently it's something in the vcxproj file. However it also appears that i'm the only one in the office that is affected. So some combination of the vcxproj file and my computer seems to be the issue.
Has anyone seen anything like this before? Any ideas on a solution?
Thanks
Still not sure what caused the issue however deleting all temporary files:
<proj>.vcxproj.user
<proj>.vcxproj.filters
<proj>.vcproj.<domainname???>.<username>.user
<proj>.suo
has fixed the problem.
I suspect it was just
<proj>.vcxproj.user
<proj>.vcxproj.filters
or both that actually fixed it but I did delete all 4 so it could have been any of them.
The change to the vcxproj file that casued the break was renaming some files and adding some files, so my guess is that one of the generated files had a stale reference that was blocking the load.
If you figure out how to get the message again, maybe you could open a bug at https://connect.microsoft.com/ and attach the zipped up .vcxproj and *.sln files so we can fix it.

i had same probleb do the following thing in windows explorer
Based on my understanding, you will get the same error even when you create every simple Visual C++ windows phone project from VS2012. In this case, I doubt that the issue is related to your VS.
And according to Konrad’s reply in this thread with similar issues: http://social.msdn.microsoft.com/Forums/en-US/cba01040-067e-4ac3-ba4c-a8a14ba3c45d/unable-to-read-the-project-file, I feel that you can check if this file: C:\Program Files(x86)\MSBuild\Microsoft\WindowsPhone\v7.0\Microsoft.Cpp.Windows Phone.7.0.targets is on your system. If it is not there, I doubt that your VS installation is wrong.
If you are not using VS Express, you could locate to the IDE folder then run these commands to check if it can help:
Please open Windows Explorer, and navigate to <Visual Studio Installation Path>\Common7\IDE
Devenv.exe /SafeMode: Launches the IDE in safe mode loading minimal windows.
Devenv.exe /ResetSettings: Restores the IDE's default settings, optionally resets to the specified VSSettings file.
Devenv.exe /ResetAddin: Removes commands and command UI associated with the specified Add-in.
Devenv.exe /ResetSkipPkgs: Clears all SkipLoading tags added to VSPackages.
If no help, I suggest you try repairing your VS or uninstall it and then reinstall it.

Why does it say "Project with that name already opened in the solution"?

I recently migrated a VSS database to TFS 2008. Using Source Control Explorer, I got the latest version of a solution with 12 projects.
When I opened the solution in VS 2005, two of the projects were not found. I am not sure why these two projects were not found, but thought it easiest to just delete and re-add them to the solution.
When I do this, VS gives me a "A project with that name is already open in the solution." The project doesn't appear in solution explorer, and is not listed in the .sln file.
Any ideas?
I had this problem and I was able to solve it using the following steps:
Remove the project from the solution.
restart visual studio.
add the project to the solution as an existing project.
I had the same message... Seems like it comes from (.csproj) project file. Under first propertygroup there is a section named
<ProjectTypeGuids>...</ProjectTypeGuids>
which generally tells Visual Studio to handle that project in some specific way. Some Guids can be found here.
First make a backup copy of that file. Then removing that section can help you open the project as usual project. As it seems that the Visual Studio thinks that the project is not the type that is specified in the ProjectTypeGuids.
This did it for me:
remove the section <ProjectTypeGuids>...</ProjectTypeGuids> in each project
reopen each project, then save to overwrite the existing project file, finally exit
reopen the solution file
pray (optional)
If anyone uses AnkhSVN instead of TFS, it's also possible, that the .sln-file need the following lines:
GlobalSection(SubversionScc) = preSolution
Svn-Managed = True
Manager = AnkhSVN - Subversion Support for Visual Studio
EndGlobalSection
in the "Global" section.
Before anyone tries tempering with their solution- and project files, figure if you may have project dependencies outside the solution, such as IIS - and you forgot to start Visual Studio in Administrator-mode
For me, the project not loaded was because it was configured to use IIS on the local machine and I needed to start Visual Studio as an Administrator.
I have to say that removing the section <ProjectTypeGuids>...</ProjectTypeGuids> could create some problems.
In fact, such a section defines the type of the project and, if removed, could disable some features.
For example, if your project was originally defined as Smart Device (C#), after removing the aforementioned section the on-device debug may not working properly.
Delete .suo file. Build solution. Add Projects.
Unfortunately I don't know the why behind the obtuse error message, I can merely provide what steps I took to get it to go away.
In my case, I had reconfigured my local IIS (<UseIIS> not <UseIISExpress>) and it was no longer hosting the URL that was in the csproj <IISUrl> field.
Editing the .csproj file in another editor and changing that field to the new URL, followed by closing and opening the solution in VS resolved the issue.
I would try hand editing the project/solution files, they are text and pretty easy to read. You can edit the file in notepad. To open up the file as text in visual studio you need to first close the solution. Then do file->open and select the sln file, but instead of hitting the open button, press on the right side where there is an arrow and select open with.. from there you can select source code editor (text).
Somehow VS 2022 doesn't create a virtual directory anymore. I had to manually create the website in IIS
I had the same problem when i migrated a website to a web app project.
Unload the web app.
Add the existing website.
Reload the web app.
The following worked for me when I moved a project running vs2010 to another laptop.
I removed exactly the following and it worked:
<ProjecctType>Guid of sorts</ProjectType>
<SccProjectName>Svn</SccProjectName>
<SccLocalPath>Svn</SccLocalPath>
<SccAuxPath>Svn</SccAuxPath>
<SccProvider>SubversionScc</SccProvider>
For those looking for this while dealing with VSTO projects...
Be sure to have the Office Tools for Visual Studio installed in your machine before opening the project.
I solved it by changing Windows' regional settings. Instead of "English (Europe)", I used "English (United States)". Others have reported similar behaviors with changing for example from "Russian (Ukraine)" to "Russian (Russia)", etc.

In my case it was corrupted vbproj file. First line was missing:
<?xml version="1.0" encoding="utf-8"?>
After adding this line I had to close the solution, delete .vs folder and open again.
I got it in Visual Studio 2022 version 17.4.4.
You may also see:
Error HRESULT E_FAIL has been returned from a call to a COM
component.
when you try to reload your project.
One way to load the project (and deal with IIS directories later) is to edit the .csproj file and set UseIISExpress to true.
Replace:
<UseIISExpress>false</UseIISExpress>
with
<UseIISExpress>true</UseIISExpress>
Then you need to close your solution and open it again and the project should load.
I encountered this issue with web application projects.
When I tried to reload the projects, the VS2022 output said something like :
"The project is configured to use IIS. Unable to find the server
'{site_url}' on the local computer. Ensure that the local IIS is
configured to handle secure communications."
Which is pretty clear. Indeed, in my case, this was caused by my website https binding that just vanished for no reason (it happened to me several times, looks like a bug with Windows 11 & IIS 10). Things got fixed when I got my https binding back (projects could load norammly).
In VS 2022 to open a legacy web project I had to:
Remove from Solution
Change framework version from 4.6.x to <TargetFrameworkVersion>v4.7.2</TargetFrameworkVersion> in from csproj
Remove <OutputType>Library</OutputType> from csproj
Close Solution and open it again (!!!)
Add project to the sln again.

"Go To Definition" in Visual Studio only brings up the Metadata

I am working in a Web Project in Visual Studio 2008. When I hit F12 (or right-click and select Go To Definition) Visual Studio is consistently going to the Metadata file instead of going to the source.
Some Points:
All the source code is C#, there is no VB.Net
All the projects are in the same solution
Everything is a project reference as opposed to a file reference (checked and double-checked)
I have tried the Clean/Rebuild Solution approach (even to the point of clearing out the Temp directory, Temporary ASP.NET Files directory, etc).
Has anyone else seen this behavior and/or know how to fix it?
Well, another developer found the answer. The specific project we had an issue with was originally added as a file reference, then removed and added as a Project Reference. Visual Studio however, kept both in the csproj file for the web site, causing the issue. He went in and manually edited the csproj file to remove the file reference to the problem project and all is fixed now
It happens when you don't add reference as a project but point to a dll or exe using Browse tab in Add Reference dialog. If you add reference using Projects tab you should go directly to the source code when you select Go To Definition.
However, if you install ReSharper, you'll go to source code even if you added your reference to a dll/exe using Browse tab.
Looks like it needs to be setup in Resharper as well. My Visual Studio does not navigate to .NET Framework source code until I enable it in Resharper.
1. close your solution.
2. delete hidden <name of the solution>.suo file in folder where your solution's <name of the solution>.sln file exists.
3. open your solution.
4. rebuild your solution.
For those using VS 2017 (I'm at version 15.3.4 at this moment) here are the simple steps:
Open your solution in Windows Explorer and close down Visual Studio
In the explorer menu, select View and ensure that the "Hidden items" checkbox is marked
Navigate to the subfolder .vs\[your solution name]\v15
Delete the .suo file
Restart VS and build your solution
That fixed it for me: F12 opened the actual source file, not the "from metadata" version.
Visual studio often suffer from a problem of going to metadata rather than your project if you shift location where you are building the project, ie you may have several versions to test things out.
Simply delete the reference and immediately add it back and everything will be sorted out.
The marked solution does not always work. You must make sure that the referenced project GUID in the project files is the correct GUID for the project you are trying to reference. Visual Studio does allow them to get out of synch in some circumstances. You can get the project GUID from the project file with a text editor.
So if project A reference project B. Open up project B.csproj in text editor, copy out project GUID from the tag. Then open up project A.csproj in text editor, and make sure that you are using the correct GUID. Search for project name "B" in this case. It should be at . Replace the GUID in the tag with the correct one. Save and reload.
Of course also make sure file based references to your projects are removed. You only want project references.
I've kill all VS instances, deleted the SUO, launch sln and it worked for me...
Remove the reference dll, Build (will get errors), ADD THE reference (you removed) then build again ... F12 on your function should then work (worked for me).

Check "View - Object Browser" and if you see more than one assembly with the same name - that's why your getting this error.
For us it was a bug in VS 2019:
If you have ASP.NET "Razor helpers" in App_Code folder the Visual Studio 2019 interprets that as a different assembly but with the same name, that hides the actual assembly.
There's no fix for that other than rewrite those helpers to partial views or HTML helpers (you will have to do that anyway if you plan migrating to .NET Core).
See this workaround on MS's site and please upvote the bug there so MS fixes it
https://developercommunity.visualstudio.com/solutions/1008795/view.html (please upvote)
#2
Another reason why same assembly can be loaded twice in the object browser is if you have a unit-test project that starts iis-express process and never kills it properly.
I figured out how to solve my problem from this post, maybe it will also work for some of you.
I followed these steps:
Close the solution.
Delete the intellisense database file for the solution: .ncb
Open the solution.
Rebuild the solution.
(I believe either step 3 or 4 regenerates the intellisense database file when it is missing)
Intellisense, "go to defintion" and "find all references" should be working again.
In my case, (using Visual Studio Professional 2015), when I had disabled the XAML designer, the F12 stopped working.
As soon as I revert the changes, and restart Visual Studio, the F12 worked again.
Checked the pattern multiple times to confirm and then posted. Hope it helps someone.
Symptom:
Visual Studio 2010 Ultimate was repeatedly failing to find references to functions, #defines, includes, etc when using the "Go To Definition" or "Go To Declaration" or "Find All References" features - oddly Intellisense was working.
Fix:
Close Visual Studio
Delete (rename if you want to be conservative) the solution .sdf file
Reopen Visual Studio
The .sdf file will automatically be rebuilt by parsing the include files in your solution
For me, the GUID solution didn't work and I couldn't find my .ncb file. (Or maybe I'm lazy and didn't look hard enough, but that's not important.) Rebuilding and restarting visual studio didn't help either.
What I did was close visual studio and delete the .dll and .pdb being referenced in the top of the Meta Data file that my intellisense kept linking to. In my case it meant I deleted my .dll and it's .pdb file from Utilities/bin/Release. (Utilities is the name of the .dll project I was having issues with.) Then I restarted visual studio and rebuilt the .dll then the whole solution. No more problems!
Just found another cause. I upgraded my web project to 4.0 but left the class libraries at 2.0. At that point all the class libraries in my solution were treated as file references from my web project. Might help someone else...
I faced the same issue and one of colleagues gave me the following solution and it worked!
If none of the above works for you,
Remove all the references and add them back (make sure the path is
correct)
Go to Solution properties, and recheck the Project
Dependencies of all projects. Make sure the project that you'll be
using is added as a dependent in the project that you are working
on.
I did all suggested steps but nothing has been changed then
finally
right click and add reference menu, project tab
simply unselected the reference project.
save the solution.
select the same project.
Rebuild the solution.
Problem sorted. Hope this will help to some one.
Below steps worked for me.
Go to .csproj file
Open it in Notepad Go to line where dll is referred.<Reference Include="">
Delete the line
<SpecificVersion>False</SpecificVersion>
or
<SpecificVersion>True</SpecificVersion>
After deleting dll files from Visual Studio first and adding them back manually from Solution Explorer --> Website --> Add --> Reference and enabling 32-bit Applications in IIS fixed it for me.
VS2017 VB.Net Windows 10 Pro - I use an assembly names "SharedCollection" which includes a VB Module named MyGlobals. One of the globals is a FileVersion. References showed metadata and the Windows Service that referenced it had an outdated setting. I had tried some of the SUO remedies above and none of them worked.
This Worked
I deleted and recreated the project reference for ShareCollection in References.
click on web site menu from VS.
Add reference...
Click on project tab from dialog box
Select ddl
Click on ok button
In my case, I had just recently changed
<mvcBuildViews>
to "true" in my site's .csproj file (to find compile errors in my Razor view files: http://forums.asp.net/t/1909113.aspx?How+to+have+Visual+Studio+2012+returned+compile+errors+on+razor+syntax+error+in+asp+net+web+page+2+ ), and when I then built I was getting errors from my within my site's /obj/Debug/ directory. From any of those files (which were out-of-date), right-clicking and selecting "Go To Definition" would give me the [metadata] version.
So for me, none of the solutions here worked, because I wasn't starting from a file that was actually in my project. Deleted that entire /obj/Debug/ directory, the errors went away, and from any normal file I can correctly use Go To Definition.
I just ran into this problem on VS 2013. Something I could (did?) not isolate was changing the GUID in the CSPROJ file. Since the CSPROJ files are checked into SVN, I could not simply change the GUID on my local dev. Instead, I was constantly SVN reverting the local change each time it happened.
First, I had to solve the changing GUID problem.
Revert the CSPROJ to the checked-in version.
Open the CSPROJ via a text editor, NOT VS.
Extract value from the pristine CSPROJ file.
{B1234567-5123-4AAE-FE43-8465767788ED}
Open the SLN file via a text editor, NOT VS.
Locate the Project reference in the solution.
Project("{FAE12345-3210-1357-B3EB-00CA4F396F7C}") = "Some.Project", "....\assemblies\Some.Project\Some.Project.csproj", "{B7654321-5321-4AAE-FE3D-ED20900088ED}"
EndProject
The first GUID listed is the Solution GUID. For every project referenced in your SLN, you should see this value repeated at the first argument. The GUID following the .csproj is the one you want to replace with the pristine GUID.
This should solve the first problem, but the "Go to Definition" landing in meta data is not solved. In our SLN file, there is a master project (our web site), so its entry in the SLN file should contain a ProjectSection entry with multiple GUID values. Here is an example:
ProjectSection(ProjectDependencies) = postProject
{AC50D230-24C4-4DCA-BAAD-355E6AF5EFBD} = {AC50D230-24C4-4DCA-BAAD-355E6AF5EFBD}
EndProjectSection
Notice the missing GUID in this collection is the one from my pristine project.
Add the missing GUID as the last entry between ProjectSection and EndProjectSection. The format appears to be per-line, and it is {GUID} = {GUID}.
Save the file.
Open your solution.
Right-click a reference in the newly-added project and "Go to Definition."
I had a circular reference between the two projects involved (which is a no-no). Had to restructure my code a bit in order to solve it as both projects were truly dependant on each other. Removing one of the references solved the intellisense problem. It was logically flawed and I probably wouldn't have noticed without this error!
This one worked for me:
Right click the dll in the reference folder in your solution
explorer
Remove dll file
Right click the Reference folder, then
Add reference to the dll file again
This can happen if you're trying to jump to the definition in a project that has been unloaded (Unavailable). Right-click the unloaded project and select "Reload Project".
I modified the .csproj file and in the Reference -> HinPath changed obj to bin and it solved the problem.
I had a variation of this issue, where when I loaded my solution my referencing project had errors until I compiled the project it was referencing. At that point the errors disappeared but F12 took me to metadata.
The issue was a dependency in the project being referenced that conflicted with a dependency in the referencing project. I manually removed dependencies from the project being referenced until one of them resolved the errors in the referencing project. After that I was able to F12 to the actual code, and the project would load without errors.
If anyone knows exactly why this happens I'm interested to know in the comments.
This little trick solved it for me - unload the referencing project from the solution and then just reload it
Best guess is that you don't have debug information. Maybe you have multiple copies of your assembly on disk and it doesn't have the .pdb file with it.
Do a search for your assembly names from your projects and delete them all and rebuild.
