Well, I agree with inconsistency in microsoft technology stack. But heck, it's PHP! PHP is evolving even more, it had only recent futures like namespaces, simple things like a()[0]. But that's not the main problem. The main problem is clean API. PHP has just a ton of inconsistent functions that you must hold in your head. From this point of view C# is one of really small number of languages that has really clean API.

Maybe I just can't understand something, but even sitting on linux for last 6 years and seeing all the great technologies I find C# really great and clean language.
