Microsoft have release ASP.Net MVC RC 1 last week - twice.  The first release was quickly refreshed to fix some issues so if you downloaded early last week, you may need to get the download again. Check here.

I have had a quick attempt to upgrade my 1 project and it all worked pretty sweetly and the upgrade process was very SIMPLE.

However.  Several of my crud views use FckEditor for long text fields.  A post-pack of these views triggers page validation:

   A potentially dangerous Request.Form value was detected from the client

Normally, turing off page request validation in the page and / or web.config will fix this :

   <pages validateRequest="false">

but for me and others (see comments at Phil Haack link above) this does not help.

So, looks like I will be rolling back to the beta until this is resolved.

Update: 

RTFB!  http://haacked.com/archive/2009/02/07/take-charge-of-your-security.aspx.  I haven't tried this yet, but it is almost certainly the solution.

Reading Paul a post on Hacked.com I saw mention of a new thing - the Web Platform Installer. This is a nifty tool that can be used to install the .Net Framework, ASP.Net, Visual Web Developer, ASP.MVC, Silverlight tools and other bits and peices. All from one very convienient and SIMPLE interface.

Using Virtual Machines for development these days I am often setting up new machines. This will save me a bit of time there. It's also great for helping friends and noobs get started with web development and will reduce the amount of time I spend on emails and awkward phone calls.

Well done Microsoft!
