Workflows are saved whenever you save the management pack. In addition, when you save a management pack, the Authoring Tool automatically identifies the WF workflow files associated with the workflow information in the management pack (each WF workflow may have multiple raw files) and builds them into workflow assemblies. The tool builds one assembly per workflow. For more information about the relationships between workflows, management pack files, and workflow assembly files, see Workflows and Management Packs.
To save and build workflows
In the Management Pack Explorer, right-click the management pack, and then click Save.
