--- Verify the correct version of your module and manifest files were installed in the Global Modules Folder here:

Thank you for sharing ! Everything worked.

Great!

Shouldn't:
-SourceLocation C:\Nuget\publish
Be:
-SourceLocation C:\Nuget\source

-SourceLocation is a path to *.nupkg files provided by repo (documentation), not source files of nuget package.
