How do I do in the visual studio so that I can see the description of a method I created?
an example as well as this image:
You have to document the method in c # and it has its syntax, it's in xml. You must add some comments before the method to recognize it, as if it were a javadoc. Here is an example:
/// <summary>
/// Descripción
/// </summary>
/// <param name="param1">Algún parámetro</param>
/// <returns>Aquí pones lo que retorna el método</returns>
However, Visual Studio has a tool that allows you to generate documentation for your methods in c #.
