Question 1

A plugin must update related records without triggering its own registered step again. What technique prevents an infinite loop?

Accepted Answer

Check context.Depth and exit if greater than 1

Checking context.Depth > 1 allows the plugin to detect recursive calls and exit early, breaking the loop.

Question 2

What is the correct way to retrieve the IOrganizationService instance inside a plugin's Execute method?

serviceProvider.GetService(typeof(IOrganizationServiceFactory)) then CreateOrganizationService

Answer

You resolve IOrganizationServiceFactory from the IServiceProvider, then call CreateOrganizationService(context.UserId) to get a correctly scoped service.
