CMS edit mode search and Community edit mode not working after upgrade to .NET 4
I have upgraded at least two projects based on Relate (Relate 2.1, Community 4.1, CMS 6.1 (6 R2)) to .NET 4 (and obviously switched to a Framework 4 application pool) and at least the moderate/admin interfaces were working just fine (not sure i checked the search). So it is possible to get it working.
Could it be a problem with the MVC version? Or some problem with handlers/modules being different in .NET 4?

Yeah, it's possible.
I am in the process of comparing configuration files to a working green field CMS 6 / Community 4 project on .NET 4 (another customer) and I have already found some differences (none of them fixed the problem, though).
The project having issues was originally on EPiServer <=4 and has behaved all the way up to the .NET 3.5 to .NET 4 upgrade, but it seems that I now have a lot of configuration cleanup to do.

After lots of agony I finally fixed it.
It seems that EPiServer sites that are upgraded to CMS 6 have to use the MVC 1 DLL that comes with EPiServer and not the MVC 2 DLL.
Why? I have no idea. The method not found (System.Web.Mvc.ViewPage.set_Html) exists in MVC 2.

While there is still a property by the same name, 'Void System.Web.Mvc.ViewPage.set_Html(System.Web.Mvc.HtmlHelper)' (as referenced in the error message) does not exist in MVC 2 and later.
In its place you will find 'Void System.Web.Mvc.ViewPage.set_Html(System.Web.Mvc.HtmlHelper<Object>)', ie the type of the property has changed.

It does exist, but not in .NET 4, so running on .NET 3.5 works fine:
.NET 4: http://msdn.microsoft.com/en-us/library/system.web.mvc.viewpage.html(v=vs.100)
.NET 3.5: http://msdn.microsoft.com/en-us/library/system.web.mvc.viewpage.html(v=vs.90)
It's still wierd that a green field CMS 6 + Community 4 works fine while a migrated/upgraded CMS 6 + Community 4 does not.
Edit: Nevermind. The dropdown in the MS reference changes MVC version as well and not just .NET version>.<

I recently upgraded a CMS 6 site with Community 4 to .NET 4 and am now getting errors.
The AJAX request made to /login/shell/Search/Index/?searchArea=CMS when searching from edit mode returns 500 (Internal Server Error) with the following stack trace:

Trying to access Community edit or admin mode (/EPiServerCommunity/Moderate.aspx, /EPiServerCommunity/Admin.aspx) also results in a 500 (Internal Server Error) with the stack trace:

Rolling back to .NET 3.5 fixes the problem, but that is not acceptable as the newest version of IntelliSearch (.NET 4 only) has to run on the site.
Following the EPiServer guides to upgrade to .NET 4 from the rolled back project results in the same errors again (bleh).
Does anyone have any insight on this or maybe even a solution? EPiServer Developer Support's answer is to roll back and upgrade again, but that doesn't work.
