Fuse8.CMF is free open source Content Management Framework based on Microsoft .NET 4.0, MVC 3.0
The CMF is free and open source. Feel free to use the CMF and improve/fix it for your own site or sites of your clients, just keep the Fuse8 copyright in the admin area and do not fork or develop your own CMF (or any kind of publicly available framework / module library) based on Fuse8.CMF. In other words: all your modifications/improvements shouldn't be public. Fuse8 Group Ltd owns the right to develop the CMF further. Drop us an email though, if you'd like to contribute a bugfix or new feature.
If you need a CMS which you want to have full contol of... if you want to work with the latest Microsoft .NET frameworks... and you don't need any ready-made modules (such as Blog, Forum, e.t.c.) which usually cause pain, blood and tears while being adopted to client needs... Fuse8.CMF is your choice. It is stable and mature enough... and it is OpenSource! So you have full control while delivering value to your clients.
If you have .NET MVC skills - you can develop any functionality you need while having all the basics (Pages, Media, Users, Content Types management and API) out of the box with Fuse8.CMF.
