Anyway to default a generic parameter to a certain type?

Question

Is there a way to provide a default type for a parameter T of a generic, something like:

class Something<T = string> { } 

I know there aren't many strong reasons for this, but I would like to hint the code client which type he should be preferably using.

Another thing, can I restrict the generic type to a ValueType? I've just seen that you can't, but still, I'd like to know why. Anyone has a clue?

Thanks!

Ok, I suppose you have the class:

class Something<T> {  } 

Now, you might want another class:

class Something : Something<string> {     // NO MORE CODE NEEDED HERE! }

This is the only and the best way.
So if one uses Something he will actually use Something<string>.
