Class design if two class needs to exchange information

If I have two classes as

class A
{
}

and 

class B
{
}

class A wants to use methods of class B and vice-versa.

What should be the best design other than the mediator pattern?

At the minimum, you should decouple your classes with interfaces. This way your intended contract between the two classes would be captured explicitly through the interfaces.

interface IA {
    // Methods for use in class B...
}

class A : IA {
    private readonly IB b;
}

interface IB {
    // Methods for use in class A...
}

class B : IB {
    private readonly IA a;
}

Other than that, it depends a lot on the nature of interaction that you are planning.
