I used web services in .Net before with WCF. Although, I really do not understand the benefits of UDDI. There is a lot of theory, but I have not found anything practical. Do you know any tutorials on using UDDi in .NET?
Found an example of UDDI in .Net
Another UDDI Enterprise SOA example from codeproject
MSDN Articles Part 1 and Part 2
jUDDI has a .net port for accessing UDDI resources.
