• MikeC23 Workflow Serialization Problem

  Hi to all, I have been using beta 2 bits for a couple of days and trying to upgrade my project with the new stuff.

So I basically have: BRActivity ...Show All

The problem is that so far I couldn't find out how to get information about the current state of a workflow, whether it's waiting for an event, etc. I have the runtime object and a workflow instance, but none of these objects exposes properties or so to get this information. Also, I'd like to pause the u ...Show All

• Sanjeev Menon Workflow Runtime Accepts HandleExternalEventActivity Events Out of Sequence

• Tyagi CredentialProvider idl and header mismatch

Philip Yes, I spotted it too :-) But your choice was not lucky - the idl content is much older than the header and it is not consistent with the actual implementation. Ignore the idl and use the header or you ...Show All
