This is code that I wrote for another project and is working great in production. I have removed some proprietary naming and haven't fully retested yet. Otherwise I would have marked this as a stable release. Detailed documentation to follow, but here is a quick start guide.

Configuration Information:

Plugin requires a custom entity to hold configuration information.

• Name - new_duplicatechecker (The schema prefix is a constant that can be changed in the DuplicateCheckerPlugin.cs)
• Attributes - new_keyattribute<string> (on the target entity the attribute you specify needs to be an int) , new_entityname <string>

Registration Information:

• Stage: Pre
• Pipeline: Parent
• Mode: Synchronous
