Many of our UK ISVs are hoping to deploy their solutions live to customers before we RTM in November of this year. In January we created a go-live license for the January CTP of WinFX – specifically for Workflow and WCF. With Beta 2 we now have a go-live license for all of WinFX.
To read the license head to http://msdn.microsoft.com/winfx/downloads/products/golive/default.aspx
NB: It is your customer(s) that need to sign up as they must source WinFX Beta 2 themselves.
