Hello,

Thank you for the question.

Based on your post, I try to enable all Exceptions in Visual Studio 2010, and then I try to run one of WebDesktop Solution Samples, SimpleDesktop.aspx page.
But unfortunately, I didn’t get any error message on my end.

Could you please provide me information regarding your current WebDesktop assembly version?

I made a video about how I enable the Exceptions in Visual Studio 2010 and how I run the sample (SimpleDesktop.aspx page).

Please kindly have review on the video and let me know if there is a missing step while I am trying to attempt your issue.

Please forgive me for lack of understanding about the reported problem.

Regards,
Hans K.
