WF4 Custom Constant Examples

Question

I am writing my own persistence instance store for WF4 based on the XmlWorkflowInstanceStore found in the .NET 4 WF and WCF samples. This example is pretty simplistic, and xml produces pretty verbosity. I have problems with how some of the objects are serialized.

I tried to use Reflector Red Gate to understand the Sql implementation used, but it is rather complicated and difficult to learn. The MS documentation for this is rather limited - one sentence is often given for complex methods.

Please, can you tell me other examples of saving WF4 (or related documentation) on the Internet that do not copy or paste versions of XmlWorkflowInstanceStore? Maybe someone else at StackOverflow wrote their own?

Answer 1

You are absolutely right that the documents here are sorely lacking, and the sample is very limited. I started working in a specialized instance repository using the entity infrastructure, but as you discovered, I found this to be a slow movement and I’m nowhere near anything that I could use myself, not to mention the release on CodePlex.

I am not aware of any blog posts or other information that will help solve this problem.

Answer 2

You've probably already seen this, but I found the code pretty straightforward: http://xhinker.com/post/WF4Xml-persistence-store.aspx

Ron Jacobs wrote a memory storage repository for testing the WF module. Check out http://wf.codeplex.com/releases/view/73842
