Solution has projects that are located outside the solution folder

Question

I tried to add my solution to the local repository by selecting File|Add to Source Control, but I got the following message.

Answer 1

Delete .vs folder in the solution folder.

This solved it in my case. Reason for the problem in my case may have been that I had moved the whole Solution folder to another location (one level up). I assume some of the old paths were still lingering in the .vs cache. (Be sure to close Visual Studio before deleting this folder.)

Answer 2

Please see Update below

Judging by the Visual Studio version number in your Solution File, I will assume you are using Visual Studio 2019, a relatively recent release (possibly a Preview version).

These are my observations:

1. I am using Visual Studio Enterprise 16.20 (Preview 3.0), and also Visual Studio Enterprise 16.1.6 (Release).

2. In either version of Visual Studio, if I create a solution under a custom directory, in my case, I use c:\Code\Projects, I receive exactly the same warning when attempting to Add a new Solution to Source Control, and selecting the version of Git that was installed with VS. Note that I have many Solutions and Directories under this location.

3. If I use the extension Easy Git Integration tools, which in my configuration is using Tortoise Git as its underlying Git service, I do not get this warning message.

4. If I OK the warning message, all files are successfully included in a subsequent Git Commit, and a valid .gitignore file is created. This includes successfully creating and pushing to GitHub, with all valid files.

5. If I create the solution in the Visual Studio default of c:/username/source/repos, I do not receive a warning from either Preview or Release versions of Visual Studio. Note that I do not have any other Solutions or Directories under this location.

I would suggest you

a) Verify that there is not a git repository in a parent folder; this has sometimes confused Visual Studio - you will find references to this issue going back several years. This could well be your problem.

b) For peace of mind, use Git from a command line. Tortoise Git also has integration with Visual Studio.

If you could provide some more information about Visual Studio and Git versions, path hierarchy, whether it is a new Solution, it might help us pinpoint the issue.

UPDATE:

I have also experienced the same issue with .Net Core 2.2 projects, and after a long night with coffee, I can reproduce this.

With an MS Test Project:

a) The Test Project is the only one in the solution.

b) The following shows the contents of the Project File.

c) Attempting to Add The Solution To Source Control i.e. Visual Studio default Git plugin, displays the message regarding source file tree:

d) Switching the source control to a third-party plugin, EZ-Git, allows the Git repository to be created without any issue.

e) I reverted back to an archived version from a zip file, with no Git integration, and removed individual packages to isolate the cause; the result of this is that when the following line is removed, Visual Studio's default Git will successfully create a repository, with no error message.

<PackageReference Include="MSTest.TestAdapter" Version="1.4.0" />

f) The issues appears to be how Visual Studio handles the dlls of the MSTest.TestAdaptor, which by default are treated as if they are part of the Project, yet they are located outside the Solution folder structure, in the c:/Users/username/.nuget directory.

g) Adding ExcludeAssets to the MSTest.TestAdaptor will remove the error message, but, fairly obviously, it breaks the Visual Studio Test Runner.

<PackageReference Include="MSTest.TestAdapter" Version="1.4.0">
  <ExcludeAssets>all</ExcludeAssets>
</PackageReference>

It may be possible to find a combination of IncludeAssets, ExcludeAssets, and PrivateAssets to allow both proper functioning of Visual Studio Git, and Test Runner.

h) NOTE: The behaviour as detailed above also applies to xUnit, i.e.

<PackageReference Include="xunit.runner.visualstudio" Version="2.4.0" />

Which indicates that the issue is related to dependencies around Visual Studio and the Microsoft TestPlatform.

Answer 3

I was facing the same issue and I solved it using GitTools extension . I have the following structure for my git repository:

In my case, I just wanted to track the files in the src folder. However, my project solution files are found in the bin folder. So, everytime that I tried to create the repository using the File|Add to Source Control or simple clicking on the git icon:

I got your message:

“ Source Control - Git The current solution has projects that are located outside the solution folder.These projects will not be source controlled in Git repository. To add all the projects to a single Git repository please consolidate all projects under a single folder.”

Which I understood that because my source files in the src folder are linked to my project solution but they are not found in the project solution folder (i.e. \bin) they cannot be added to the source control using “Source Control – Git”. Probably, I understood the message in the wrong way, but my solution works.

Just let's try to double-check the path to the solution folder:

1) Right click project solution -> open folder in file explorer

2) And we can see that my project solution folder (i.e. bin folder) does not contain the src folder that I want to track. So, VS git is complaining about it.

So, I solved the problem by installing: a) Tools -> Extensions and Updates -> Git tools

Note: You will probably need to restart Visual Studio.

b) After the installation, you will have another menu: Git Tools

c) Just select: Git ini and you will have your new repository. You will not notice any particular change.

d) You can go again to the GitTools -> GitBash and just type Git Status to test:

Notice that the git repository was created in the /projects/DRRsiddonOri3/bin folder which contains the project solution.

The price to pay is that you will have to commit using Git Bash from the GitTools menu(i.e. manually from Git Bash), if it bothers you.

However, I was not able to add /src folders because it is out of the git repostiroty (/projects/DRRsiddonOri3/bin).

In my case, I needed to create the git repository in /projects/DRRsiddonOri3/

So, I follow this path: GitTools->GitBash and change the directory from /projects/DRRsiddonOri3/bin (project solution) to /projects/DRRsiddonOri3/ and create the repository

Test: Windows 10 Visual Studio Community 2017 Version 15.9.6

Answer 4

For anyone who experienced this right after adding a xUnit .Net Core test project, the solution/workaround is in a comment from tintow on the excellent answer from dmcquiggin:

I was facing the same problem and found a fairly simple workaround. As dmcquiggen pointed out, this is related to MS Test. I found that by simply unloading the MS Test project before checking in resolved this problem and the test project is still checked into source control. Then just reload the MS Test project and it appears to work as normal. Maybe the underlying test package is not included but thats not a problem for me. – Tintow Oct 11 '19 at 11:59

Answer 5

Double-check in command-line by going to the root folder of your Git repository, and type:

git status

Do check that your solution file does show up in the list of files to be added.
Otherwise, that means the Git repository is in one folder, while the solution and its projects are in another path entirely.

Answer 6

This was happened with me a few months ago (on Visual Studio 2017). And following solved the issue :

1. Close Visual Studio
2. Delete .git folder (which is hidden by default)
3. Open Visual Studio. Add the solution to source control

Don't forget to check in case there is any .git folder in the project root folder.

Note : You'll loose the historical data.
