I wouldn't describe it as painful myself. But, I would agree with sentiment. Having spent 3+yrs working with Java and then moving to C# (2yrs+ dev) has been a pleasant experience. C# is great language with features like delegates, Indexers, Pointers and Unsafe Code (executed in an unsafe context) and constraints on type parameters.

In contrast, I hate the msdn documentation for C# and still have a soft spot for java documentation.And yes, C# v Java is not the same as JVM v CLR
