.NET OPC Results

Just wondering if anyone has used any of the current .NET OPC wrappers that are on the market. If so, which one(s) did you like the best & general results good/bad. Did you choose based on performance or ease of use?

The main two that I think my choice will be between is the one from Advosol (http://www.advosol.com) & Metadynamics (http://www.metadynamics.com/index.htm).

Thanks,

Darren

I have used metadynamics for the client and it works fine.
I haven't had any problems with it. Everything as far as calling opc servers, groups, etc. is the same as using VB6 with opc automation. Its pretty close to invisible, it just makes opc work in .net.

I haven't ever used advosol. I just checked out the advosol product. It looks good, I'll probably check out the evaluation sometime. I noticed it has a wizard and some extra help features. Metadynamics does not.

I chose Metadynamics because it was the only product I could find for .net, and its worked so I never checked out anything else.
