Dynamic Data Store issues after upgrading to 7


Just upgraded a CMS6r2 site to 7 and we are running into the following error:

The property Criteria exists on both the old and new definitions but does not have the same type and is not convertible between the types.

Any advice would be greatly appreciated.

Do you have this atrribute on your classes [EPiServerDataStore(AutomaticallyRemapStore=true)]

I believe they made changes between cms6 and cms6 r2 so you probably have to update stuf when upgrading to cms7. Have a look at this blog post from paul smith:

Thanks for the response, Eric.  I have used this method succesfully before for custom properties that we have built from scratch, but this appears to have something to do with the VisitorGroup store so I cannot add the attribute you have mentioned.


For further clarification, here is the rest of the stack trace:

Most likely the reason for this is a problem with assembly redirects. Please, check in your web.config:

  • there should be only one assemblyBinding element inside configuration/runtime element
  • the assemblyBinding element should have namespace defined: xmlns="urn:schemas-microsoft-com:asm.v1"
  • assemblyBinding should contain dependentAssembly element with correct bindingRedirect for EPiServer.ApplicationModules assembly (the one that contains type for the Criteria property)

Sergii was right!
