I have developed an SP Feature in C# and tested in development environment, confirming it is functioning correctly.

When I publish to production and enable on a site, I just get a single line in the ULS log when it triggers:

Loading and running the event receiver class TCBSEmailHandler.TCBSMetadataExtractionEventHandler.TCBSMetadataExtractionEventHandler from assembly TCBSEmailHandler, Version=1.0.0.0, Culture=neutral, PublicKeyToken=49f071f6ad2c11c6 failed. Object reference not set to an instance of an object.

What can I do in the production environment to debug this error?

A similar question of mine regarding debugging in development was answered here, but I'm not sure if/how I could apply similar logic to a deployed solution.

You really shouldn't be debugging in production. Instead, add additional logging capabilities to your app and do more defensive coding. By defensive coding, I mean that if your code is calling some method to get an object, check to see if you got the object before doing anything with it.

  • Fair enough. I was already trying logging and that was failing so I was looking for another way around it. I've asked a new question to target the logging issue I'm having here.

If you are using visual studio ultimate to develop your feature IntelliTrace would be an option. IntelliTrace team done a great job to plugin SharePoint events with IntelliTrace .
