State Machines are back in business!!!
Now exactly after a year since .NET Framework 4 release, as part of the .NET Framework 4 update 1 that got released last month, Microsoft has brought back the support for "State Machine" workflow types.
This will bring huge relief to customers who wanted to migrate.NET 3.5 state machine workflows to .NET 4
Some of the related important additions are,
• Support for SQL Azure as Workflow Instance store
• Provides max connection retries property to re-attempt a connect to database
• New activities to model compensation behavior for easy to use by new custom workflow host
For developing applications from Visual Studio 2010 SP1, you can download the install here
Note, you must be running on SP1 of VS2010 for this to work.
If you have server applications running with the .NET Framework 4 and want to update then, you need to install it from here. Steve Danileson has provided good pointers to State Machine Workflow Labs and other important changes here.
