Steve Martin has released more details on the .NET Framework 4.0. For me, the information on Windows Workflow 4.0 is very interesting, as this is the first major update since its inception:
Windows Workflow Foundation 4.0
Significant improvements in performance and scalability
· Ten-fold improvement in performance
New workflow flow-control models and pre-built activities
· Flowcharts, rules
· Expanded built-in activities – PowerShell, database, messaging, etc.
Enhancements in workflow modeling
· Persistence control, transaction flow, compensation support, data binding and scoping
· Rules composable and seamlessly integrated with workflow engine
Updated visual designer
· Easier to use by end-users
· Easier to rehost by ISVs
· Ability to debug XAML
For many ISV’s, the most interesting bit is “Easier to rehost by ISVs”, as many ISVs have looked at re-hosting the excellent visual designer, but have found it to difficult to do. Hopefully this will make their lives easier.
