@rubot: Mostly, yes, however (a) the Contoso Cookbook example has not been updated, and (b) the dependency on the Calisto controls will be a problem. Tim Heuer at Microsoft who maintains those controls (which the Contoso Cookbook relies on for a specific feature later in this series) has added breaking changes. If you can work around that, this would still be a helpful series.
Also, I'm no longer supporting this series ... it's been years ago since I recorded it and I'm just not as familiar with the material since I've moved on to other concerns. Sorry!
@Arjun: Yes, provided the caveats above.
@Ved: I'm pretty sure it does not matter. They have equivalent functionality. It's really a matter of which language you're more familiar with.
