no source available to run tests in Visual Studio 2017

Question

I'm having trouble debugging a project. When I double click on the tests to open them, it says "no source available" and I can not also debug or run a specific one. I can only run them all by the tool or by git bash using dotnet test.

Any idea what that might be? These problems started when we migrated to ASP.NET Core.

Project is with net461.

Thanks,

重新启动Visual Studio并构建测试程序集对我来说是成功的。
