[severity:It bothers me. A fix would be nice]
hi,
the classes DragEventArgs and MouseEventArgs posses teh same method to retrive the mouse position: "GetPosition(IInputElement)".

It happend in my project, that I had to process the position in Mouse events and drag events.
To avoid dublicate code I had the idea to pass the event args to a method, but it wont compile.

How about an interface, which proviedes access to "GetPosition"?

Can you please share the minimal repro sample for this app?

[miloush]

This is practically an API request, you don't need a repro. The author has one method that processes both mouse and drag events, and he needs to call eventArgs.GetPosition in both cases.

The proposed API is something like

public interface IPosition
{
    Point GetPosition(IInputElement relativeTo);
}

and then changing MouseEventArgs, DragEventArgs and presumably also StylusEventArgs to implement IPosition. It could also be implemented by MouseDevice, StylusDevice and IManipulator.

I am not quite convinced the benefit of that is worth the costs.
