How can i use 3D view inside WinForms?
Should i use XNA ?
I found this tutorial: http://create.msdn.com/en-US/education/catalog/sample/winforms_series_1
Use WPF. You can mix and match the forms. WPF has a winforms container you can drop in a window and make fill it. But you can use WPF out of the box fine with little education - tip = make the window fixed size or resizing will hose your controls. Doing that right is hard.
Then put a wpf panel for a picture where you want the 3d. Cut and paste 3d wpf code from the internet.
