I want to download and install razor view engine for ASP.Net MVC 2. From where i can download and install?
Possibly a bit outdated but you should maybe take a look at this post.

Razor is capable of running standalone so it is entirely possible to provide the wiring yourself. Whether or not you need to be using .NET4 or not I am not 100% sure of. On another note MVC3 is at RC status and has a Go-Live license which emans you could technically start using now and when the RTM hits (soon) just upgrade.
