Rich Turner from the Indigo team has a post about creating web services using existing technologies:
Building Service Today.

In general, he has a few points:

• “avoid the network wherever possible“.


• you have choices: asmx, remoting, queuing, Enterprise Services


• Use the facade pattern to abstract the service layer from the underlying business layer. Also use the facade pattern to abstract the Enterprise Services classes (if any) from the Business layer.


• Think about transactions, either at the web service level or at the Enterprise Services level (if the transaction spans several business components)
