How to use +, -, *, / etc in C# Generic

[My interest]

Question is how to make the following class compile?

class foo<T>
{
private T a, b;

public T Sum()
{
return a + b; // this line does not compile.
}
}

The background is that I want this class to be instantiated by all the
"numeric friendly" classes (i.e. those support operator like +,
- ...). These should include both built-in types, (e.g. double) and
user defined class.

Thanks.

As I stated previously - if you are using .NET 3.5 I can fix this for
you instantly; let me know if this is an option.
If not, it is a major PITA.

Didn't we just have this thread? Didn't you start that one too?

Hint: just because the operator is now + instead of *, that doesn't make
it a new question.
