Migration Overview
The following list summarizes the primary principles of migrating from the Windows Media Services version 4.1 SDK to the Windows Media Services 9 Series SDK.
ActiveX controls are no longer used.
There is no object in the Windows Media Services 9 Series SDK that is the functional equivalent of the Windows Media Unicast Traceview control. Tracing can be done programmatically through trace listeners in Visual Basic .NET and C# or by using a trace macro in C++.
All programming is done through APIs.
The new plug-in architecture expands the type of plug-ins beyond Authentication, Event Notification, and Authorization.
The Cougar administration interfaces for administering a remote server are no longer used. That functionality can be accomplished through DCOM configuration and programming the server object model.
