  • Your plugin will have to call retrievemultiple or fetch request for a list of contacts with the same name excluding the currently created one.

    And if the count is more than 0, there's a duplicate and you have to throw InvalidPluginExecutionException with some message and a use will get a message box like this.

    But if you want to prevent the user from creating the record, you've got to do it in Pre-Stage.

    There's a sample code for CRM 4.0 in the following post. You can reference it to re-write it for CRM 2011.
