C#

The spec wrote:

An expression is classified as one of the following:
...
• A method group, which is a set of overloaded methods resulting from a member lookup (§7.3). A method group may have an associated instance expression and an associated type argument list. When an instance method is invoked, the result of evaluating the instance expression becomes the instance represented by this (§7.5.7). A method group is only permitted in an invocation-expression (§7.5.5) or a delegate-creation-expression (§7.5.10.3). In any other context, an expression classified as a method group causes a compile-time error.

You mean my understanding that "method group is a set of methods with the same signature" is wrong?

And it works if SOMESTRUCT is defined in the C# app. But, what if it isn't, and is a struct that is in a C++ DLL? I just can't cast to a SOMESTRUCT.
