WF 4 SqlWorkflowInstanceStore: Supported SQL Server versions

The SqlWorkflowInstanceStore is an out-of-box instance store implementation in Workflow 4 that uses Sql Server to store instances. This instance store was written to use the following databases:

  • Sql Server 2005
  • Sql Server 2008

Unsupported versions include:

  • Earlier versions of SQL Server
  • All SQL Server Compact versions (since SQL Server compact does not support stored procedures, which SqlWorkflowInstanceStore uses.)

For more information, see Sql Workflow Instance Store.
