Are Generics Covariant, Contra-Variant, or Invariant?
Generics FAQ: FundamentalsGeneric types are not covariant. Meaning, you cannot substitute a generic type with a specific type argument, with another generic type that uses a type argument that is the base type for the first type argument. For example, the following statement does not compile: class MyBaseClass {} class MySubClass : MyBaseClass {} class MyClass<T> {} //Will not compile MyClass<MyBaseClass> obj = new MyClass<MySubClass>(); Public Class MyBaseClass ..

Generics FAQ: FundamentalsGenerics have native support in IL and the CLR itself. When you compile generic server-side code, the compiler compiles it into IL, just like any other type.

The client-side compiler uses that generic metadata to support type safety.
Related QuestionsWhat's the problem with .NET generics?
Andy Mc's .NET Framework FAQNET generics work great for container classes. But what about other uses? Well, it turns out that .NET generics have a major limitation - they require the type parameter to be constrained. For example, you cannot do this: static class Disposer<T> { public static void Dispose(T obj) { obj.Dispose(); } } The C# compiler will refuse to compile this code, as the type T has not been constrained, and therefore only supports the methods of System.Object. Dispose is not a method on System.
