My one big beef with generics is that they only work through constraints! With templates, the compiler checks the validity of a template only when applying it to a concrete type; a generic, OTOH, needs to be valid as an independent entity. And this means that you are stuck with the limitations of the constraints: you cannot specify that your type has a constructor accepting parameters, you cannot specify static methods, nor operators. With generics, you can only pass complete types as generic parameters; templates accepts types, templates and integral constants. You can't have partial specializations with templates. Typedef. This is the most annoying limitation I found in C#. You cannot type: typedef vector<MyClass> MyList; and have it valid in the whole project.
