>Don't both parts have to have the partial modifier? Although I suppose it would be possible to add the modifier to the generated class.

Yeah, you're right, my bad ... but adding just the partial modifier to the generated class wouldn't be that much of a burden.

Actually, looking at this a little closer, I see that all the 'metadata' classes are declared as partial and those are the ones that are most likely to need extending.....

Ah ... so no problem then (I've not used that stuff, nor even looked at it, so take what I say with a grain of salt <g>).
