• Visual Studio 2008 (Pre-release) duplex contracts behind a loadbalancer

  Hello, Just starting to work on some duplex communication samples. Can someone confirm that this will work behind a loadbalancer Regards, Ruurd Boeke Probably :-) - Most load balancers are configured to return the client to the same server. Though not ideal it prevents a lot of programming issues ( like not having to track session state in a DB ) If you are using a true load balancer im not sure , but my hunch is it may not work. The issue is not so much the server talking back to the client but the state on the server . Most Duplex channels implementations have a program model where a request is intiated by the client , w ...Show All

• Software Development for Windows Vista How to pass a Strongly-Typed Dataset to a workflow

  Hi, Can anyone tell me how to pass multiple parameters one being a strongly-typed dataset to a workflow. It would be good it I could pass the dataset by reference too What I'm trying to achieve is two-way communication between the host and the workflow via a dataset. There doesn't seem to be many examples of this on the web - can anyone help Thanks!
