问题 Is there a way to run c# forms application without showing a gui window (like a console application). I'm trying to take screen shorts of webpages loaded into a webkit.net control.

Browser screenshot as bitmap in WP7

I'm trying to get the screenshot of a given URL as a bitmap image on the Windows Phone. The WebBrowser class does not seem to have the DrawToBitmap method. Any pointers on how to get this working? You can't take a screenshot of the WebBrowser Control as there seems to be a bug with the way it works with WriteableBitmaps. An alternative method could be to send the URL to a web service which takes a screenshot on the server and returns it back to your app. Use WriteableBitmap to render the WebBrowser control and its contents to a bitmap as described by Laurent's article Taking a screenshot from
