Möglicherweise etwas veraltet, aber vielleicht sollten Sie sich diesen Beitrag ansehen.

Razor kann eigenständig betrieben werden, sodass die Verkabelung durchaus selbst bereitgestellt werden kann. Ob Sie .NET4 verwenden müssen oder nicht, ist mir nicht 100% sicher. In einem anderen Punkt befindet sich MVC3 im RC-Status und verfügt über eine Go-Live-Lizenz, die Sie technisch sofort verwenden können, wenn das RTM (bald) ein Upgrade durchführt.

Verwendung von Matthew Abbotts und My Razor View Engine von Codeplex. Sie könnten Folgendes tun. Es unterstützt keine Modelle oder Layoutseiten, bringt Sie jedoch in die richtige Richtung, wenn Sie sich für diese Route entscheiden. Ehrlich gesagt würde ich nur auf MVC 3 aktualisieren, wenn die Zeit reif ist. Dieser Code basiert auf meinem Blogbeitrag unterhttp://buildstarted.com/2010/11/22/making-your-own-viewengine-with-markdown/

Sie müssen Ihrer global.asax die folgende Zeile hinzufügen:

ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new RazorViewEngine.RazorViewEngine());

es sei denn, Sie möchten beide Motoren in diesem Fall einfach entfernenClear()

Der beste Weg, um einen MVC Razor-Motor zu bekommen und zu lernen, wie man ihn benutzt, ist von Scot Gu! Der Guru des gesamten Razor-Projekts. Sein Blogbeitraghttp://weblogs.asp.net/scottgu/archive/2010/10/22/asp-net-mvc-3-layouts.aspxist sehr einfach zu befolgen und zeigt Ihnen, wie Sie den Gerüstprozess über die Package Manager Consel in VS verwalten.
