Description of the method from the interface

Question

I want to write a beautiful and well-documented code base for my project.
One thing I want to do is get the details of the method for my black part of the code base code. Like this:

/// <summary>
/// The methods summary
/// </summary>
/// <param name="numX">Number x.</param>
/// <param name="numY">Number y.</param>

But I do not want to write it again and again for each class that extends the interface, instead I want to write it in the interface and show it in all classes that implement this method.

Is it possible?
