The sample you provided causes the error too. Steps to reproduce (from your provided sample)
Step 1) Load solution into Visual Studio
Step 2) Select Default.aspx
Step 3) Select "Internet Explorer" as Debug Browser
Step 4) Once Default.aspx loads (Dates should be March 5 - 11 In upper left corner)
Step 5) Press Forward Arrow ( > ) to move 1 week forward on the date selector
Then the program should hang-up and Visual Studio will become unresponsive (VS will briefly pop-up displaying "Opening the file..." then become unresponsive) and Visual Studio needs to be completely terminated by manual means.
Does this not happen on your end? If so, perhaps there is a setting that needs to be changed somewhere?
I believe it is March 12th that is causing the issues as I can load any date past this week in a week view, but if March 12th is included (in a week or workweek's view) then the program crashes.
Please and thanks,
