I have 20 years programming experience and C# is one of my favorite languages. It feels so expressive and doesn’t get in your way nearly as much as Java does. I feel like I’m writing the code I want to write instead of writing the code someone from 30 years ago with a fetish for boilerplate wanted me to write.

C# is a great language but I’ll always choose Java because the ecosystem around it is so vast. Often times some client library you need has a c# port maintained by one guy and he hasn’t updated in years.
