Moving on from Mouse Events to Multi-touch

Well, let’s try another post.  First time I’m writing a public development journal, so we’ll see how it goes.

I really just want to share knowledge I’ve gained over hard hours of research and trial and error so others can learn from my own experiences.

So, there’s some built-in manipulation support in Silverlight meant for something like zooming in or rotating an image.  Which is great if you have a simple app viewing some single object.  There’s also some handy gesture libraries emerging and some built-in support via XNA.  I found out about that from this other post here.

It’s really quite cleaver and according to the current marketplace guidelines should pass certification as its not one of the forbidden XNA references (when using Silverlight):

4.2.5 The application must not call any APIs in the Microsoft.Xna.Framework.Game assembly or the Microsoft.Xna.Framework.Graphics assembly when using any methods from the System.Windows.Controls namespace.

In either case, what I really wanted was to be able to track the specific multiple points of the player and not just some gesture they may be trying to input.
