Re: Workflow TV - How To Build Workflow Services with a Database Repository

You can store the workflow definitions in Oracle - I'm using Entity Framework 4.1 in my code so you would need a provider that works with Entity Framework.

However, at this time we do not have a Workflow persistence provider for Oracle. You won't need this unless your workflows are long running.

Can provide a web.config with the VirtualPathProvider? I didn't know that.

I wonder if you could support a VirtualDirectory and then place a web.config file in the VirtualDirectory with the config you need if that would work.

It would be worth a try.

Re: Workflow TV - How To Build Workflow Services with a Database Repository

I don't understand your comment about WorkflowServiceHost being limited. It is no different than a WCF ServiceHost. The WCF Service Host will host one service per host. The WF WorkflowServiceHost will host one workflow per host.

However, you can have multiple services and workflow services in you web application. In fact you don't really deal with the WorkflowServiceHost or ServiceHost classes unless you are self-hosting so they are just another part of the infrastructure most of the time.

WCF services have a collection of operations
WF services also have a collection of operations

The main difference is that the WF service can enforce a messaging protocol with certain operations being available only at certain times.

My guess is that if you can build your solution with WCF services you can also build it with workflow services.

You can use configuration with WF Workflow Services see this post for an example.

Re: Workflow TV - Parent / Child Workflows

@kachchhu: WF4 is the name I use for Windows Workflow Foundation in .NET 4 from the System.Activities namespace.

This is different from the workflow implementation from .NET 3 in the System.Workflow namespace.

Re: Workflow TV - How to Unit Test a WF4 Workflow that calls a WCF Service

rojacobs — Tue, 25 Jan 2011 14:54:24 GMT

This video uses smooth streaming. When you change to full-screen mode after a few seconds it should switch to high-resolution.

There is a High-Quality WMV download you can use as well.

Sorry about the resolution. I bumped it up to hi-def so it should be better now.

Re: endpoint.tv - WCF AppFabric Caching Behavior Sample

rojacobs — Fri, 24 Dec 2010 20:56:45 GMT

Agreed - I wanted to make a client endpoint behavior but it turns out that you cannot intercept a call on the client. There are other ways to do this but they involve messing with the client proxy typically.

@srikalyan: well for people who need to generate services from XSD this is a nice convenience. Otherwise they have to do quite a bit of work with svcutil. Of course if you don't have the need to build services from XSD then it doesn't help you much.

Re: Workflow TV - How to test activities and workflow services with XamlInjection

rojacobs — Thu, 21 Oct 2010 23:44:12 GMT

Thanks for the feedback - I hear you. We want to provide ways to work with exisitng mocking frameworks when possible. XAML based workflows are in a special category of thing that other mocking frameworks can't really help you with. Of course once you cross over into the code of an activity then you can always mock at that level with whatever you like

Re: endpoint.tv - AppFabric Caching vs. IBM eXtreme Scale benchmark

rojacobs — Thu, 07 Oct 2010 14:25:33 GMT

I've added the link to the benchmark report so you can check out the numbers yourself. It appears to me that in all tests except for Large Object without failover that .NET performed better.

The difference in perf however is small - of course - the difference in price is great.

Re: Workflow TV - Workflow Services as a Batch Job

rojacobs — Thu, 02 Sep 2010 12:47:14 GMT

I have not done any direct performance comparisons to a Windows Service doing the same work. It seems to me that for most things the performance should be close to the same since mostly they are waiting for work to do. Having the workflow with AppFabric doing the job gives you the added benefit of the monitoring store which is really cool for this sort of thing.
