Research direction

Start with the New .NET File command in the C# Dev Kit flow and reproduce the issue by adding MSBuild Directory.Build.props and Directory.Build.targets to a C# Console App in sequence. Done means both files can be selected and added together without the duplicate-file message; no source files or tests are named in the issue.
