I've encountered several issues while I was trying to test the product via the samples demonstrated in your site.
After I installed the Sample.Page.UsState and I try to use it in the Composite C1 CMS solution it isn't recognize.
ViewBag isn't recognize in the Razor view pages.
I have the console on which I install the different packages (like MVC player), on IIS under default websites I have the composite C1 website which is map to files under wwwroot and through webmatrix i can open the composite c1 in VS.
of course when I add something to my solution it doesn't reflect in the site hosted in IIS so it seems that I need to publish the site again but then I might override the mvc player installation.
Can I develop a complete site in MVC outside the Composite C1 solution and embedded it through the Composite console using the MVC player ?
