I love Stack Overflow… They saved me from a Windows Phone 7 problem.http://stackoverflow.com/questions/4253186/webbrowsertask-fails
Basically, I was trying to use a WebBrowserTask to open a URL in a browser from my phone app. It kept opening a browser, but without the address bar populated.
Turns out, when you are debugging your application, it fails. Running outside of debug mode, the browser opens to the proper link just fine.
WebBrowserTask task = new WebBrowserTask();
task.URL = Uri.EscapeDataString(sURL);
