Question

Visual studio tells me that I dont implement the methods if I dont declare them “explicitly” in terms of interface.
Here are my methods:

    public interface IGetMenus
{
    List<Menu> GetMyMenus();
    void InsertMenu(string topic, string subTopic);
    void UpdateMainMenu(int menu_id, string topic);
    void UpdateSubMenu(int menu_id, string topic);
}

Here is an example of how visual studio wants me to implement the interface:

List<Menu> IGetMenus.GetMyMenus()
  {
  }

Why is that?

Answer 1

Usually the reason is that you have a method with the same name + parameters but a different return type already.

In C# this is not valid, the only way to implement the interface in this case is to do it explicitly or move/rename the other method.
