I have a c# .Net 3.5 application that creates xaml files with drawings in them. I'd like to insert a thumbnail into the file so that the user gets some indication of the file contents in Windows Explorer.

Any ideas what approach to take?

Regards David

    I think it isn't .Net question. For appling custom thumbnails you should learn how to register file type in Windows registry. – Stremlenye Apr 28 '10 at 16:40
  • I think it's more of a shell extension task than a registry task. I found this example http://www.codeproject.com/KB/shell/shellextguide9.aspx but I can't find anything in the managed world. – David Hollinshead May 14 '10 at 14:14
