I am creating a plugin that uses the MapPoint COM object. Initially I got the error
"The type is marked as eligible for type equivalence, but the containing assembly is not loaded as fully trusted"
I resolved this by not registering the plugin in the Sandbox, i.e. no isolation.
However, now I am getting the error
"Retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154 Class not registered"
I compiled the plugin as x86 but then I was not able to register it. I also changed the AppPool to allow 32-bit apps but then CRM does not work anymore at all. I am not quite sure where to go from here. Any input is appreciated.
