I'm occasionally asked by ISVs about how they can establish a partnership with Microsoft.  We offer Microsoft Empower for ISVs to meet this need.  While it's not free, it is a good value, offering:

  • Up to five internal-use software licenses:
  • One (1) software license and up to five (5) Client Access Licenses (CALs) for:
  • Development and testing license: One (1) MSDN Premium Subscription Media Kit and five (5) user licenses**
  • ISV Advisory Service (10 hours)
  • Check out https://partner.microsoft.com/global/40011351 for complete details.
