The question of how to debug a .NET Extension has come up a few times in the SalesLogix Business Partner newsgroups as well as on the slxdeveloper.com forums. I've answered this a few times in those locations, so this might be a repeat of info for some, but I did think it was worthwhile to post again here as well.

Here's a step by step to debug your SalesLogix .NET Extension:

1. Create your .NET Extension and compile it in debug mode
2. Add it to the Extension Manager and add whatever scripts to launch it
3. While the project is open in VS, go to "Debug" and then "Attach to Process".
4. Find "SalesLogix" on the list of running processes. Select it and then use the "Select" button to ensure that you've chosen to debug "Managed".
5. Set a break-point in VS in your code
6. Run the script that uses the extension and it will stop at your break-point.

Have fun!
