I also happen to really like C#, and used to use it quite extensively. But, it's also not perfect 
. The bifurcation of reference vs value types is there, and there are some footguns with using value types. Some of you might remember how lambdas used to desugar in for loops, capturing the value only for the last iteration in some cases (that was fixed at some point). The .NET standard lib used to be extremely allocation happy and it was a challenge to write performant code. Although methods were sealed by default, classes weren't which ought to have been the better default. C# made the same mistake as Java of having a volatile field keyword, which is completely backwards in today's thinking - it's not the field that's volatile, but accesses to it (and each of those may have their own memory ordering requirements to boot). There was no good memory model for the language (not sure if there is one now, on par with say Java's memory model). null is still present. Exceptions are unchecked, which is fine if you hate incorrect usage of Java style checked exceptions, but makes it incredibly difficult to write robust code. And so on.
