git failed with error - is a directory add files inside instead

Question

I have created new MVC project in my existing solution.
While adding these new project to existing solution, I am getting below error.

I am using VS 2019 now. Earlier, I was using VS 2017 in which everything works fine.

These issue is occurring for all directory in project. e.g. xml/ css/jquery.
Even though we manually add those files in folder it still showing same error.

Git failed with a fatal error.

error: mvctestproject/wwwroot/lib/jquery-validation-unobtrusive/: is a directory - add files inside instead
fatal: Unable to process path mvctestproject/wwwroot/lib/jquery-validation-unobtrusive/

Answer 1

Check if, as it was the case here:

• you have a process with a lock on a file in that folder
• you can, in Team Explorer, right-click the file and select "Ignore this local resource".

The idea is Git is not able to reach a specific file in that folder.
