C# is my favourite server side language by far. I work with both PHP and C#.
C# ftw!
Oh and by the way - to get started programming C#, just install "Microsoft Web Developer Express" (not Microsoft C# Express) and you can start straight away. No messing around trying to get a development server set up or anything like that.
