Recently, I have created a new virtual machine since my old Windows XP image was getting little slow, so I decided to put all the latest stuff on it. I installed Windows Server 2008 RC2, Visual Studio 2010, SQL server 2008. Then I installed ASP.NET MVC3 (RC2) and try to run some of my "older code". This has become quite a task, first there were some classes totally missing... Finally I got everything working, but for some reason, I cannot hack the security settings, so post HTML to the server (either comments or HTML markup for my CMS) cannot pass through Request.From. There is not much online about this yet since this is a pretty new build. I have found this forum thread, talks about the issue, but none of the solutions worked for me quite yet.
