CRM 2011–Plugin Registration Error: Assembly must be registered in isolation

While registering a CRM 2011 plugin I kept getting the following error in only one of our test environments.

Assembly must be registered in isolation

After a lot of searching I found out that the reason I was getting this error in only one environment was that I was not designated as a “Deployment Administrator”. Once I had that fixed, the error went away!

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Action failed for assembly xxxxxxxxx, Version=, Culture=neutral, PublicKeyToken=yyyyyyy': Assembly must be registered in isolation.
