There are circumstances when it is most practical to implement Custom Servers using the XML coding method. These circumstances include:
When the controls are relatively simple and well documented.
When the controls map well to an existing object, but you need to replace the implementation during a recording session (Test Record), or replace or add a small number of test object methods during a run session (Test Run).
When a full programming environment is not available–implementation using XML Custom Servers requires only a text editor.
However, when implementing a custom control with XML:
You have none of the support provided by a program development environment.
The XML implementation includes C# programming commands, and runs only in the Application under test context.
