static method cannot implement interface method, why?

Question

interface IXXX
{
    void Foo();
}

class XXX : IXXX
{
    public static void Foo()
    {
        Console.WriteLine(\"From XXX\");
    }
}


class Program 
{
    static          


        

Answer 1

You use interface to avoid using concrete class during instantiation. You can't access static method through instantiated class, so implementing interface methods with static methods is not allowed.
