thanx for the replys.
I've tried Awesonium, but the .NET 1.7 version is in development (actually there is just a 1.7 alpha without .NET support). I will try when it will be ready...
0plus1: it's strange to say, but there isn't source code. I've only dragged the webkit component on the window form and set its URL property to index.html so to load the game when the app starts. The definitive EXE with all files is just a ZIP in exe format that starts my app (extracting all in the temp folder) when you double-click the EXE.
