Edited Unassigned: AjaxFileUpload April 2013 Issues All IE Versions [27417]

After updating to latest April 2013 Control Toolkit, getting the following ASP.NET exception. Running Windows 2003 R2 and IIS. Google Chrom and Safari work fine.

I have spent the last 5 hours trying to get the AjaxFileUpload control to work with IE 10, 9, 8 and 7. I installed the package using NuGet and I installed it manually. Every time I test the control with Internet Explorer the Drag Drop area is not displayed. Only a single file upload is provided. If I select a file and upload it, I get an IIS exception (see below).

I'm using VS 2010 Premium and using 4.0 Net Framework. Has ANYONE tested this new version with Internet Explorer (any version)? I have attached 2 images (My VS 2010 environment) code sample and the IE browser display of the page. This is not showing the drag drop area. I did not even go that far to put in the upload code.

Thanks for the work you guys have done with this software. Hoping for an easy resolution.

I have attached 3 image files showing my problems (VS 2010 Environment, IE 10 Browser Display, and IE 10 Javascript exception found via debugger)
