SYMPTOMS

After you upgrade to the Microsoft .NET Framework 2.0, memory usage may increase for .NET Framework Windows applications that use the ServicedComponent class to call Microsoft COM+ applications.

CAUSE

This problem occurs because a ServicedComponentProxy object is created and is collected over time every time that a COM+ call is made.
