Unlike Java, there isn't runtime casting in the generic class client code. Conversely, it generates Common Intermediate Language (CIL) for each of these classes, though equivalent methods share a ...

When dealing with generic methods in classes or interfaces, the compiler generates bridge methods to maintain compatibility with pre-generics code. 3. Arrays and Generics: Due to type erasure, arrays ...
