I'm trying to make a WinForms application with embedded XNA according to this sample: http://creators.xna.com/en-US/sample/winforms_series1
What I'm looking for are code samples that use code sample above to study more on the subject. I'm creating a desk game.
Thanks for help
Well, here is one but also check this project at Codeproject. There are numerous sites, just search XNA and Winforms in your favorite search engine.
Responding your question, I'd recommend you join XNA forum. My experience is people there are cool and reliable. Here is a nice post with source code of your particular interest from such forum.
