I downloaded this zip file from my account downloads area :
Telerik_UI_for_WPF_2015_3_1104_Demos
...and I am loading ExamplesCS_WPF.sln in VS2015 update 1.
I assumed I could run any of the projects as I liked, but after trying a handful, each fails either at build or run time.
I did try using the WPF upgrade wizard, that didn't seem to help. I am up to date with Telerik Control Panel. Is there some other prerequisite?
I found no readme or other discussion of how to build or run this demo project.
