I want to create a .NET CF application for Windows Mobile 5. In this application, I want to load a COM object based on the ProgID (or CLSID).

How do I load this COM object in such a way that I can access its methods as if it were just another .NET object?
In addition: how can I configure the projects / solutions in Visual Studio in such a way, that when I debug the application, I am sure that the COM object that is loaded is the one that is installed on the device, not one that may be accessible through the debugger?

I have tried adding the .ocx file as a Reference, but I get an error, and I am not sure about 'question 2'. I have also tried loading the COM object using

Type type = Type.GetTypeFromProgID("my.prog.id")
MyObject myObject = (MyObject)Activator.CreateInstance(type)

...but this results in an InvalidCastException on the second line.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
