Cannot cast between generic types

Question

I\'m trying to do this:

interface IA
{
}

class A : IA
{
}

class Foo where T: IA
{
}

class Program
{
    static void Main( string[] args )
    {
          


        

Answer 1

interface IA
    {
    }

    class A : IA
    {
    }

    interface IFoo where T : IA
    {
    }

    class Foo : IFoo where T : IA
    {
    }

    class Program
    {
        static void Main(string[] args)
        {
            IFoo fooA = new Foo();
            Foo fooIa = fooA as Foo;
        }
    }
