CRM 2013 – Plugin Registration Error

Error: Plug-in assembly does not contain the required types or assembly content cannot be updated.

This error was occurring when I try to update a Plugins assembly using Update Assembly window of the CRM SDK PluginRegistration.exe. I was able to register this same assembly couple of hours ago and now without major changes I’m unable to register it.

Problem turned out to be that another developer has updated the same plugin assembly with extra plugin classes added to the assembly. I was getting this error; since I did not have those extra plugins in the assembly I was trying register.

This is something to note about when registering plugins for the testing purpose in a shared environment without check-in the code.

Full error I got:
