  I would like to know what the overhead is when calling a workflow nativly from a another workflow compared to call it as an exposed web service. This would be valuable information when modelling workflows. InvokeWebService is going to end up going out on the network - or at least through sockets (if the workflow happened to be in the ASP.NET process). I wouldn't recommend that approach for speed - InvokeWork ...Show All
