Issues after upgrading a clean & simple 5.6.2 to 6.0 v 6.0.0.444 on .NET 4.0

1) The upgrade was clean (no errors). To allow the site start (and allow the upgrade process to start) I had to manually edit the web.config to map the proper telerik.web.ui. I mean where it says "<dependentAssembly>  <assemblyIdentity name="Telerik.Web.UI" ... "
I was using the DNN 6 INSTALL package. I don't know if this problem is avoided with the Upgrade Package.

2) The Media module now does not display the picture is had configured

3) Host > Module Definitions does not work: "A critical error has occurred. / An item with the same key has already been added."
Nothing is rendered on the page.

Same problem from 5.2.2 to 6.0.0 444

This is for both Extenshions Modules, not pages = Admin and Host and Module definitions module. Does not do the above from a clean install of 6.0 to 6.0 444 but file manager problems and any file management wont work = object not set to reference of an object

Need a binding redirect for messiging on WebformsMVP to 1.0.0.0, have to change web config to 4.0 from 3.5 to get file manager and other features to work.

Don,

The next pre-release of 6.0 will have the duplicate key issue fixed. The easiest way to find the version number is to look in Host Settigns, .444 was CTP2.
