Hosting .NET Workflows .NET 4+------------------------WF Manager

• Host application integration• WF-driven UI

• Systems integration• Service-based architecture

• Async execution of a single workflow instance with bookmarks and tracking

• Explicit, fine-grained control of the WF runtime

• Async execution of multiple workflow instances of a single definition

• Supports durable timers, persistence, tracking, WCF SOAP, correlation, etc.

➔ Part of Workflow Manager Tools for Visual Studio (2012 only!)

➔ TestService (console app) ➔ Deploy & run workflows in it➔ Attach Visual Studio to the process➔ Update exe.config

➔ Some limitations

Multi-tenancy Through scopes & isolation

Scopes

➔ Workflow manager scope➔ Dedicated service bus topic➔ Gets created at deployment of first

workflow➔ “A scope is a named and

securable container for Activities, Workflows, Instances, configuration and child Scopes.”
