MSBuild binlog viewer downloads have fallen off the cliff since ~March: msbuildlog.com/stats/ My interpretation is that AI is solving MSBuild issues, as well as less and less people using MSBuild. Also hopefully modern MSBuild and SDK is more pit of success.

There's a new PowerShell SDK and CLI distribution in town, and it's from Devolutions! After speaking with @jsnover.com at #PSConfEU, I took the plunge and adapted #PowerShell to fit our needs. This is not a full fork, but it includes targeted improvements: github.com/Devolutions/...
