Implement partial methods across multiple assemblies
<p>In one of the applications I am working on, there are two basic functionalities included: Create and Update.</p>

<p>However, there is a need sometimes to add custom code, so I thought of extending the code by allowing 3rd parties to write and embed their own code:</p>

<p>OnCreating
OnCreated
OnUpdating
OnUpdated</p>

<p>Is there a way to enable the above across multiple assemblies? MEF might help here?</p>

<p>Thank you
Regards</p>
