Don threw a comment at Becky and I today about not being good bloggers (we've both been slacking recently). So I thought I'd blog this: It's come to my attention that some customers are experiencing weird interop problems between .NET 1.0 and WebSphere 5.0. I thought WebSphere uses Apache Axis and I know that .NET and Axis interoperate as verified by SOAPBuilders testing so I'm not sure where these interop issues are coming from. I've started looking for the right people at IBM to talk to about this. Perhaps Sam knows.
