RSRP-94239 error CS0029: Cannot implicitly convert type 'void' to 'int'

Issue is visible to: All Users

using System;

class A
{
    static void Main()
    {
        int x = new C().Foo(1, 1); // error CS0029: Cannot implicitly convert type 'void' to 'int'
    }
}

abstract class B<S>
{
    public abstract int Foo<T>(T x, S y);
    public void Foo<T>(int x, T y){}
}
class C : B<int>
{
    public override int Foo<T>(T x, int y)
    {
        throw new NotImplementedException();
    }
}

Overload resolution is wrong.
