C# doesn't erase all generics; but there's also some type erasure happening: nullable reference types, tuple element names, and the object/dynamic distinction are all not present in .NET bytecode; these are only stored in attributes for public signatures, but are erased for local variable types.

C# also has huge amounts of syntactic sugar: `yield return` and `await` compile into huge state machines; `fixed` statements come with similar problems as "finally" in java (including the possibility of exponential code growth during decompilation).
