Dragging and Dropping on a WPF InkCanvas

So I am working on the Image handling code for our app at the moment, specifically the drag and drop portion of it and boy howdy am I already annoyed at it. Firstly, if you work in VS the good ol IDE with alzheimers the thing about it is that people tell you to run in Administrator, which is all well and good up until you want to drag a file/image/x from your desktop into you app, it doesn't like it, it will not allow it and it will not tell you why. That is 30 minutes of my life I am never getting back.

So you don't run as administrator, you put a debug hook in you skeleton of a event handler and BAM, it works, it gets picked up and you are happy you thing that you will be able to get the dropped in object out of the parameters as easy as pie. Mistake number 2

All file data likes in the DragEventArgs, you have to dig through e.Data to find all your stuff out, going through more or less a massive conditional logic block asking things like

if(e.Data.getDataPresent("FileName") except it might not be a FileName, it might be something else, the ones I know of are FileName and Text, but there are probably more and you need to handle that data different as well.

So, I started hacking away and then decided screw this noise, the basic functionality of this has been done a million times, sure we will have to modify it for our resource server some point down the track, but until that day comes, I will let someone else do the work

His example code for this is very good, it is neat, clean and much better than I would have done
