Embedding XNA in WPF: how to update gametime?

Question

I'm trying to embedd an XNA game into my WPF application. I'm following the code shown here: http://remember.waralan.fr/?p=497 (not in english)

My problem is, gameTime is never updated, and is always 0. How can I increase as it would be in a normal XNA game?

Answer 1

I haven't found any way to update gameTime by itself, so I updated it manually using C# stopwatch.
