It has been very good since around 2007/8 when ASP.NET MVC released. That was the first good MS web framework. You needed to avoid EntityFramework / WCF / Unity and anything coming from the Enterprise group. There were some amazing OSS frameworks and libraries.

Then when .Net Core happened it was compelling and once that matured a no-brainer. On the MSFT the Alt.Net side won, MS hired many of the good people and the Alt.Net supporters inside Microsoft run the show nowadays. So now it's fine to run a largely MS stack on .Net.
