What is the difference between this:
void MyMethod(IMyInterface value) { //... }
and this:
void MyMethod<T>(T value) where T : IMyInterface { //... }
The main functional difference is that you can know the actual type of the object inside of the generic method. The T parameter will contain the actual type which can advantageous in certain scenarios.
In the non-generic case you cannot guarantee access to the underlying type of the object. Most of the type you could grab value.GetType() but the user could pass Null and thwart you.
