Hi,

I've hit an interesting problem. I have a Lightswitch application that use Telerik controls. Everything works beautifully until I upgrade the control from 2013.2.611.1050 to 2013.2.724.1050; i.e. SP1. After the upgrade the control simply don't show in the application, I get not errors or warning there is jus a blank space where the control should be. I have suspicion that I'm missing an assembly but nothing indicates which.

I'm image the first question will be whether the references in the LS client project and my Control project are the same; the answer is yes (I had the same thought) I've checked them repeatedly. I've also done a clean build.

Hi Michael,

Could you check whether the referred Telerik assemblies are NoXaml? In your installation folder there are two subfolders - Binaries and Binaries.NoXaml. If your project uses binaries from Binaries.NoXaml folder, these binaries does not contain the theme styles and this can be the reason for not seeing the controls.
