Hello,

Upgrade of site went 'well'. But I have an issue with a custom control that I had implimented into the templates of the back end users form. I had customized it to allow a useful feature of 'searching for users'. But the upgrade has caused a break and is giving me a message "The control must be assignable from type "System.Web.UI.WebControls.HiddenField" and must have ID "hProvidersAbilities""

Ok! Solved!
You need to add the two hidden fields that I'm appending next.
<asp:HiddenField runat="server" ID="hProvidersAbilities" />
<asp:HiddenField runat="server" ID="hDefaultMembershipProviderName" />
I got caught by the first error msg, added the hidden control, but then got the same message again right away. I double checked the id and it forced me to add 2 hiddenFields.

Hope this helps someone :)
