Was this change intentional? It removes the "InsideDirectory" and then you try to create a file as a directory?

Hi @OzBob Sorry about that, I was on vacation. I just got back. What I mean is that the directory "InsideDirectory" doesn't seem to be created anymore? Unless I'm missing something, which is possible.

I just created a test project and ran the original code. It worked as expected:

dotnet run

Created directories.
Created a new file in the root.
Created a new file in the InsideDirectory.

I then ran the code from this PR and it failed:

dotnet run
