Fix to blank LightSwitch app bug with Visual Studio 2012

I needed to populate a database I’m designing with some test data and thought to myself “LightSwitch will be ideal to knock out some screens”.

One hour later I got a LightSwitch screen to actually display! Until then all I got when running it in Desktop mode (the default) was a blank window hosting Silverlight (right click to verify)

After lots of searching and playing around I found the answer near the end of this very long thread

  1. Navigate to the Client.Properties folder inside your project
  2. Open OutofBrowserSettings.xml
  3. Change <SecuritySettings ElevatedPermissions=”Required” /> to <SecuritySettings ElevatedPermissions=”NotRequired” />
  4. And you may also want to then make the file readonly

 Now, when this happens again I will be able to find my own post to resolve it! Enjoy!

P.S. This isn’t specific to Visual Studio 2012 … but the post title corresponds to how I was searching 🙂

  • Silverlight 5 RC–TrickPlay and Media Remote Controls

    At the time of the Silverlight 5 beta, I’d put together a simple demo around some of the new media capabilities (not all of them as I’ve never been too hot on the DRM stuff) in Silverlight 5. This demo involved playing the trailer from the then new X-Men movie…

  • Silverlight 5 RC–MarkupExtensions and DataContextChanged

    When the Silverlight 5 beta shipped, one of the things that I wrote about was trying to use a markup extension in order to link between something like a Click event on a Button and a method to be invoked on the ViewModel rather than on the view. And so if I…

  • Silverlight 5 RC–Platform Invocation

    One of the big features of Silverlight 5 for me is platform invocation. If you’ve been around .NET for a while then you’ll know that this has (since day 1) represented the “get out of jail free card” because it allows .NET code to call into pretty much any…
