I originally started building a web app in VS 2012. I upgraded to 2013 and continued building the app. The app is using the latest releases of the AJAX and Reporting tools.
However, I have some issues when I run the app after I have built it in VS 2013. I have weird errors popping up.
One example:
An aspx page with some combo boxes for the user to provide report parameters. Once the parameters are selected, user clicks the button to show the report using a reportviewer.
When I build the web app with VS 2013 and run it, I get this error: Sys.WebForms.PageRequestManagerServerErrorException: Value cannot be null.
Parameter name: key
However, when I build the app with VS 2012 and run it, everything works as it is supposed to.
Has anybody seen anything like this? I'm baffled - and sad that I have to continue using VS 2012. I'll be happy to post some code snippets if necessary.
Thanks!!

Well it appears this is actually an issue with VS 2013 browser link and has nothing to do with Telerik.
