Is there any practical difference between these two extension methods?
class Extensions
{
public static void Foo<T>(this T obj) where T : class { ... }
public static void Foo(this object obj) { ... }
}
I was poking around in Extension Overflow and I came across the first form, which I haven't used before. Curious what the difference is.
