Content Manager extension points

Content Manager extension points are the APIs you can use to implement Content Manager functionality: you can use the TOM.NET API for developing templating and Event Handler and Workflow, the Content Manager Explorer extension API to add custom controls and behavior to the GUI, and the Core Service API to interact with the Content Manager from a third-party application or third-party GUI.

If you use 32-bit COM components inside your .NET extensions (e.g. .NET event handlers), your code will fail on a 64-bit operating system. To prevent this, put your COM component in a COM+ app.
