In a world where lots of CMS platforms are popping up, Orchard is definitely one of my favorites. The biggest reason for me is that it is a .NET CMS.
For those who don’t know what Orchard is:
“Orchard is a free, open source, community-focused Content Management System built on the ASP.NET MVC platform already powering sites of many major brands and organizations. Originally created by Microsoft, it is now maintained by the Outercurve Foundation, a non-profit and IP-neutral open source software foundation.”
I you want to know more or if you are interested in getting to know Orchard, I can highly recommend Orchard Harvest, the second ever Orchard user conference which is being held in Amsterdam (another reason to go) on the 13 and 14th of june.
