I'm impressed. The migration of the Universal Thread Web Service in .NET took 8 hours. I received a lot of help today from Universal Thread. But, in overall, it went well.
What I like the most is that I don't have to create a context anymore as this is already builtin. I also do not have to deal with ISAPI or ASP listener. It is faster and all that which much less code. But, the most interesting part, I didn't have to connect on VPN to the server to register a DLL, compile the Web Service, update the ASP listener file and test it. Everything has been done locally and only by FTP, I was able to upload my ASMX, the DLL files and that's it.
