Workflow and Host Communication in WF 4.0-Parameter Passing

Thu, 12 Apr 2012 17:58:33 GMT

Workflow host is an application responsible for executing the workflow and managing different workflow lifecycle events like start, completion, idle, unloaded etc.Now the workflow host should be capable of exchanging information with the workflow. This information exchange can be broadly categorized into: a) The parameters/arguments needed to start the workflow and to get the results back after workflow has executed. b) The intermediate data needs at different stages of a long running workflow (e.g. when the workflow is waiting for a specific input like Manager's Approval). In this post we will concentrate on the different mechanisms of parameter passing and getting results back. In the subsequent posts we will move into more complex scenarios related to long running workflows.

Practical Applications of BizTalk Server, Windows Workflow and SSIS

Tue, 28 Sep 2010 19:14:01 GMT

In an effort to maintain control over the proliferation of application servers and data, many organizations have undertaken projects to consolidate and integrate systems. One of the first hurdles in undertaking an integration project is determining the most efficient integration technology. Unfortunately, just within the Microsoft stack, there are technologies that consistently cause confusion and are often misused. For example, the lines are continuing to blur when comparing BizTalk Server to Windows Workflow especially now that hosting Workflows using Windows Server AppFabric can provide functionality that appears similar to BizTalk. However, there are still quite a few giveaways when you need one versus the other. Underneath most applications, we commonly find a data platform and for many organizations, their platform of choice is SQL Server. The intersection of just these 3 technologies leads many to ask the question, "if I want to integrate System A with System B, which technology should I use?" Many times there are no hard and fast rules, but with some careful thought and consideration of organization demands and technological capabilities, the fog will lift and a clear answer will emerge. This post will by no means provide the definitive answer, but I will provide a few common scenarios that might help illuminate the path.
