Today I stumbled on this video about PowerWF (a visual PowerShell Development tool) creating an OpsMgr MP.
The video shows how PowerWF can be used with PowerShell scripts and converts it to a workflow,and creating a MP with the data for OpsMgr.
Visual PowerShell Development with PowerWF Studio makes Microsoft’s PowerShell accessible to everyone. PowerWF Studio allows users to drag-and-drop PowerShell commands to create powerful workflows that are easier to understand and modify than conventional scripts.
The version I demo'd (and what's shown in this video) is 2.2 which will be out by May 8. The difference between that and 2.1 (available for download now at http://powerwf.com) is the smooth SCOM deployment and some very cool data mashup tools.
