C# how to show/use the description of an interface method in the interface implementation?

Question

In VisualStudio (InteliSense): How can I make the description of an interface method (property or what ever) on mouse over "visible" for the interface implementation, if the typedef for an object of the interface implementation is not the interface declaration (for example var or in this case InterfaceImplementation)?

Example:

public interface Interface
{
    /// <summary>
    /// Description I like to write just once,
    /// but like to have it "visible" in each implementation.
    /// </summary>
    void Method();
}

public class InterfaceImplementation : Interface
{
    public void Method() { /* method impl without description */ }
}

class Program
{
    static void Main( string[] args )
    {
        // on mouse over interfaceImplementation.Method() I can not see the Interface.Method description. 
        InterfaceImplementation interfaceImplementation = new InterfaceImplementation();
        interfaceImplementation.Method();

        // on mouse over varInterfaceImplementation.Method() I can not see the Interface.Method description. 
        var varInterfaceImplementation = new InterfaceImplementation();
        varInterfaceImplementation.Method();

        // only on mouse over interfaceRepresentation.Method() I can see the Interface.Method description. 
        Interface interfaceRepresentation = new InterfaceImplementation();
        interfaceRepresentation.Method();
    }
}
