Runtime

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

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

Custom Activities

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> 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

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
