Calling a Static Method on a Class Type passed as a Generics Argument.

[ESPNSTI]

Hi,

I'm trying to call a static method on a class type that is passed into a
method through generics, for example:

public bool Test<TestStaticType>() where TestStaticType : TestStaticBase,
new()
{
return TestStaticType.Foo(); // <-- The error is produced here
}

It's giving me the following error:
'TestStaticType' is a 'type parameter', which is not valid in the given
context

Why doesn't that work?

FYI, I'm using VS2005 Beta 2.

Thanks,
Erik

From the CSharpFinalWorkingDraftApril2005.pdf:

* A type parameter cannot be used in a member access or type name to
identify a static member or a nested type (§10.8, §14.5.4).

Which basically means that you can't use static methods on generic
types.
