In Java, I have a package that translates XML metadata from one standard to another. This package is ultimately accessed through a single function and sends all of its output through a PrintStream object.

What do I want to achieve: I want to perform some time consuming operations from my MDI winforms application (C# - .NET).

In the meantime I want the UI to respond to user actions, including manipulatio...
