it would be nice to get up to date step by step instructions for .net example

Just downloaded and unpacked "sample files for dotnet.zip" from under Synapse/Spark/DotNET/.

I had a sight hope on the off chance it might contain something like instructions and a working solution file for Visual Studio ( community edition would work perfectly well ).

Hope this is good enough description of an issue. Please let me know, I would be happy to better describe the issue at hand.
