I've actually taken a liking to JetBrains Rider for .net... the .net platform is decent, and with some of the new .net Core stuff, I like it for web/REST backends, but could not stand needing to use Visual Studio.

It's generally been a much more enjoyable experience, much less buggy, much faster. I use the Vim plug-in. Rider also has a Windows Forms designer for when that comes up.

Didn't know it existed until a colleague mentioned it, and was impressed.
