I have used C# for almost 21 years, so far. Written for .NET Compact Framework, ASP.NET 1.1+, WinForms, MSMQ, back-end server code, you name it.

Nothing beats this language for getting REAL work done in my books.

Tooling - Visual Studio absolutely unmatched. Core Lib/Type System - one of the best. ASP.NET Core - great rewrite of the old ASP.NET. Very fast. Runs everywhere.

C# as a language has evolved very, very nicely and I try to use the new feature whenever it makes sense.
