PRB: System.AppDomainUnloadedException Error When Pipeline Components That Are Implemented in Managed Code Are Registered as Poolable

In Commerce Server 2002 (with or without Service Packs 1 and 2), a System.AppDomainUnloadedException error occurs when your pipeline component runs if the following conditions are true:

• You implement the pipeline component in managed code (for example, in C#).
  
  -and-
• You register the component as CATID_POOLABLE (poolable pipeline component).

To avoid this problem, do not register any pipeline component as poolable that is implemented in managed code.
