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
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
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
WorkflowInvoker Foo WorkflowInvoker.Invoke(new foo)
WorkflowApplication Foo Foo Foo varwa = new WorkflowApplication(new Foo) wa.Run() wa.Cancel() wa.Unload() wa.Persist() wa.ResumeBookmark()
WorkflowServiceHost WorkflowServiceHost Foo Foo Foo
WF Persistence Basics Host WorkflowApplication wa.Persist() Idle
Collecting Workflow Events Workflow Runtime Scheduler Tooling raises events Tracking Provider Tracking Profile add Monitoring Data notify Tracking Participant Application Host
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)
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
Activity Authoring CodeActivity AsyncCodeActivity Activity NativeActivity DynamicActivity
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
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
Custom Activities demo
Customized Authoring Environment • Visualization of process • Visualization of instance information • User construction or editing of process definition • Customize the visualization of an activity
Custom Activity Designers Surface key data Display contained elements ExpressionTextBox WorkflowItemPresenter WorkflowItemsPresenter
Designer Rehosting Items Host Editing Context Services Designer
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
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!
