Registering "Assembly in Isolation" for CRM2011 Online

Nov 9, 2012 at 7:31 PM

The original software was written using CRM2011 On Premise.  The user is promoting to CRM2011 Online.  

The VITACore solution package contains a CollabSolutionsCoreActivities Plugin Assembly that fails when I try to import the solution into CRM Online.   The error is “Assembly must be registered in isolation”. 


There are several items to consider:

1. Confirm user has System Admin rights in the deployment manager

2. Register in CRM2011 Online sandbox mode

3. Confirm that the Plug-in Registration Tool has been installed in Visual Studio


Please review the article noted below for instructions on how register in isolation for CRM2011 Online:
