C++/CLI with .Net Core is not supported

[mcr222]

if (path.extname(file) !== '.csproj' && path.extname(file) !== '.vbproj' && path.extname(file) !== '.fsproj' && path.extname(file) !== '.props') { logger.warning('Invalid file. Only the following file extensions are supported: .csproj, .vbproj, .fsproj, .props'); return; }

Whe support was added for it in .NetFramework it was not added to .NetCore:

Just a note if anybody wants to use it you can use two tasks in Azure pipeline one for the .Net Core and one for the C++/CLI (using the NetFramework taks).
