TFS Project not Bound to Source Control

I had a solution with 5 projects but two were in source control but never showed as checked out.

I was looking for a way to "bind" these to TFS that option was not showing up.  This link shows how to do it.

To bind source control projects and solutions to Visual Studio

  1. Highlight the project or solution you wish to bind to Team Foundation source control in Solution Explorer.

  2. From the File menu, choose Source Control, and then choose Change Source Control.

  3. In Change Source Control dialog box, click Bind.

To unbind source control projects and solutions to Visual Studio

  1. Highlight the project or solution you wish to unbind in Team Foundation source control in Solution Explorer.

  2. From the File menu, choose Source Control, and then choose Change Source Control.

  3. In the Change Source Control dialog box, highlight the solution or project you wish to unbind from source control, and in the toolbar, click Unbind.

TFS 2018 - VsTest Platform Installer - MSTest - Warning: No test is available in...

I am able to successful runs MSTest unit tests in Visual Studio 2017 but it would not run on the TFS 2018 server (or TFS 2015 before I upgraded).

While setting up TFS 2018 to run unit tests I was getting the following warnings.

Warning: [MSTest][Discovery][C:\Agent\_work\2\s\[......]
Warning: No test is available in C:\Agent\_work\2\s\[......]

Information: Additionally, you can try specifying '/UseVsixExtensions' command if the test discoverer & executor is installed on the machine as vsix extensions and your installation supports vsix extensions.

THE FIX

By default the "Search folder" was set to $(System.DefaultWorkingDirectory) that path was looking at c:\agent\_work\2\s\MyProject.Tests\obj\Release\MyProject.Tests.dll but that folder did not have the following DLLs.   

Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter.dll
Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices.dll
Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices.Interface.dll

Changing the  "Search folder" to $(Build.StagingDirectory) corrected the issue and the test ran successfully.

Here are are the tasks in the build.

Here is where the value for the path had to be updated.
