Configure your project to launch another instance of devenv.exe in the
debugger. On the command line pass the name of a test project using your
converter.

Hi Rob,

most type converter methods can be debugged if you drop a PropertyGrid on a
form, and set the SelectedObject to an instance of your component. This way
you can easily debug the conversion methods, and GetProperties() should also
be no problem.

A problem is the serialization, wich is called by the design-time
environment (e.g. Windows Forms designer). To debug it, you need a 2nd VS
instance and debug the other one.

However, there is another simple solution to test your serialization code:
From a test program, call your type converters CanConvertTo() and
ConvertTo() methods for the type InstanceDescriptor.

ConvertTo() should return an instance descriptor, that can be used to create
a new object of your target type from code:

   TargetType value = new TargetType(...);
   ...
   InstanceDescriptor id = typeconverter.ConvertTo( context, culture,
value, typeof( InstanceDescriptor ));
   TargetType value2 = (TargetType) id.Invoke();

If value2 is initialized correctly, then you are on the right track.

HTH,
