I'm deploying an asp.net mvc 2 app on windows 2008 R2 and I get error that there is no system.web.mvc.dll, Should I install mvc2 on the deploy machine ?
You can actually deploy without MVC being installed on the server by deploying the MVC DLLs with your project. Put the following DLLs into your bin directory and it will run fine
System.Web.Mvc System.Web.Routing System.Web.Abstractions
If your server is on .Net 3.5 SP1 then you only need to deploy the Web.Mvc DLL, if its not running SP1 then you will need to deploy all 3.
There is an article by Phil Haack here detailing this more http://haacked.com/archive/2008/11/03/bin-deploy-aspnetmvc.aspx
