I have an ASP.NET web application, all fine in VS2010, but in design mode in VS2012 shows "error creating control. error hresult e_fail has been returned from a call to a com component" for all ASP controls and custom usercontrols. Projects appear to build and run properly. WHAT SETTING OR UPDATE IS MISSING PLEASE?

I saw alot of these posts around, one of which suggested putting various assembly tags to system assemblies in web.config which I did, and upon restarting VS it seemed to work. I have not yet tried removing them and retrying. On a separate note, I had to do a VS2012 update to allow backward project compatibility with 2010. Maybe this had an effect also.
