  1. FT17 Spice Up Your Applications with WF 4 Matt Winkler Program Manager mwinkle@microsoft.com http://blogs.msdn.com/mwinkle

  2. Where This Talk Fits Visual Studio IIS Management Activities PowerShell Application Host WCF Runtime WF Runtime Persistence Monitoring Storage Process Host

  3. WF in 3 minutes or less • WF is three things • Activities • Runtime • Tooling • To use WF in your app • Build activities • Create workflows which use those activities • Let the runtime deal with running the activities

  4. Embedded Process Engine

  5. Embedded Process Engine • Separate execution logic from application • Modular grouping of logic • Standard vs. Premium Customer order processing • Process will be updated without redeploying the application • Coordinate asynchronous, potentially long running work

  7. Loading Workflow Foo.dll Compile via XAML Build Task <Activity x:Class=“Foo" > <x:Members> <x:Property Name="argument1“ Type="InArgument(x:String)" /> <x:Property Name="argument2” Type="InArgument(x:String)" /> </x:Members> C# (DynamicActivity) Activity x = ActivityXamlServices.Load(xamlFile); WorkflowInvoker.Invoke(x, new Dictionary … ); Execute with DynamicActivity

  8. WorkflowInvoker Foo WorkflowInvoker.Invoke(new foo)

  9. WorkflowApplication Foo Foo Foo varwa = new WorkflowApplication(new Foo) wa.Run() wa.Cancel() wa.Unload() wa.Persist() wa.ResumeBookmark()

  10. WorkflowServiceHost WorkflowServiceHost Foo Foo Foo

  11. WF Persistence Basics Host WorkflowApplication wa.Persist() Idle

  12. Collecting Workflow Events Workflow Runtime Scheduler Tooling raises events Tracking Provider Tracking Profile add Monitoring Data notify Tracking Participant Application Host

  14. Custom Activities

  15. Custom Activities • Activities are the mechanism to do the important work in your domain • Customize the authoring components for the logic in your application • Compositional model allows you to create the right level of abstraction for authoring • Replicate the real world in your building blocks (custom composites)

  16. Customer –xRM Application Framework Client • Declarative development of relational business applications using flexible models and dynamic services. • Business Application Services • Multi-tenant controller • Event pipeline, solution sandbox, audit, data quality, client sync, indexing • Robust web services • Enterprise-scale, role-based deployment Forms / Views Workflow Security Application models in metadata Entities Multi-tenant controller SQL

  18. Activity Authoring CodeActivity AsyncCodeActivity Activity NativeActivity DynamicActivity

  19. Control Flow Styles A Parallel • Execution pattern for composite activities • Any activity can be the root • Control flow activities can be composed Activity 1 B Activity 1 PickBranch PickBranch PickBranch C Activity 2 Activity 2 Approve Reject Delay (TimeOut) Activity 3 Activity 3 Action A Action B Action C D Activity 4

  20. ActivityAction • Creating a mechanism to let your workflow authors to plug custom logic into your activity at prespecified “holes” • Consumers extend an activity in a natural way, through more activities Approval Payment Process Order Receive Order Reserve Inventory Ship Order

  21. Custom Activities demo

  22. Customized Authoring Environment

  23. Customized Authoring Environment • Visualization of process • Visualization of instance information • User construction or editing of process definition • Customize the visualization of an activity

  28. MS Research – Trident

  29. Summary • Highlighted 3 different aspects of WF in your app • Showed key types for using WF • The activity model provides a lot of power, write custom activities! • Designer rehosting brings workflow visualization into your application • Highlighted some interesting applications built by our internal customers

  30. Next Steps • File… New Project… Workflow • Other talks @ PDC • Workflow Internals, next session, this room. • WF Services, WCF and AppFabric talks tomorrow • Chalk talks • Come see us in the booth!
