title: How can I get if a crm dynamics 2011 update plugin was triggered by an activate/deactivate/merge action?
body: <p>I build a plugin that runs in account update message that makes some validation not to duplicate the record. But if I try to disable that account or merge with another one it triggers the plugin.</p>
  
  <p>How can I tell if the plugin was triggered by an activate/deactivate/merge action, or event mode like the one in CRM Dynamics 2011 <a href="http://msdn.microsoft.com/en-us/library/gg509060.aspx" rel="nofollow">Save Event Arguments Reference</a>?</p>
