Using the Web Browser control inside a Windows Mobile 5 application, while running on a smart phone causes parent forms to close automatically.  This appears to be a windows mobile bug.

 In August, I presented at the Twin Cities Silverlight User Group.  Here is the code that was reviewed.

After upgrading from SilverLight 2.0 Beta 1 to SilverLight 2.0 Beta 2 I started receiving the following strange behavior.  The project would compile just fine (and execute with no issue), but he design view of my XAML page stopping showing the preview.  Although the project compiled just fine, with zero failures, if you look in the error list, you would see an error.

Don't just install SilverLight 2.0 Beta 2 overtop Beta 1, despite what you might hear from people for whom it worked.  You may encounter this problem, posted by Tim Anderson.

Hopefully you won't have a problem, or if you do the process of uninstalling and installing again is easy enough of a solution.  However, if you are like me it won't work and you should follow these steps, posted by BradleyB.

In both SilverLight 2.0 Beta 1 and Beta 2, I've experienced the situation where my break points are not being hit, while debugging my application in Visual Studio 2008.  It took a few attempts at figuring out why this was happening, but the answer was to clear the browser cache.  I have not determined exactly what causes the browser to cache the SilverLight application.  It appears to happen only intermittently for me, with a need to clear the cache a half dozen times a day. 

Notice that your break points will have a question mark on them, when the browser is running the cached version.  Additionally, of course, any recent changes you made to the application won't be reflected, when running the cached version, despite a browser refresh (F5).  You must go into the browser (IE6) options and clear the cache, then refresh.

While doing a little Ajax web programming, I hit this javascript error that stumped me longer than I care to admit.  Unfortunately the javascript error doesn't tell you which dropdown has the multiple selection, so not a trivial one to debug if you have several controls in the mix.

Error:  "Sys.WebForms.PageRequestManagerServerErrorException: Cannot have multiple items selected in a DropDownList."
 
I was changing the selected values based on other activity in the form.  Because I was using AJAX (which uses Javascript to do the magic), not your typically web request that would re-populating the drop down list all over again on the server side, I was causing the error by using the code below.  Note: the drop down list remembered the selected item from the last web request.  Setting the selected property of one item, doesn't clear the other selected flags.

On and off over the past few weeks I've been experiencing the hard knocks of using ASP.Net 2.0 profiles.  The most important lesson learned was this:  ProfileCommon is only available if you created your project as a "Web Site" not if you use a "Web Application".  Much to my disappointment, I reviewed many Microsoft articles and MVP blogs the talked of the many benefits of the ProfileCommon class, all failing to mention that you must use a Web Site project.

This is a nice little post that I finally found.
