asp.net-mvc - Razor View エンジンのダウンロード方法

Question

ASP.Net MVC 2 の razor ビュー エンジンをダウンロードしてインストールしたいのですが、どこからダウンロードしてインストールできますか?

Answer 1

少し古いかもしれませんが、この投稿を見てください。

http://stefan.rusek.org/Posts/Using-Razor-with-ASP-NET-MVC-in-Four-Easy-Steps/26/

Razor はスタンドアロンで実行できるため、配線を自分で用意することは完全に可能です。.NET4 を使用する必要があるかどうかは、100% 確信が持てません。別のメモとして、MVC3 は RC ステータスであり、技術的には今すぐ使用を開始でき、RTM が (間もなく) アップグレードされたときにすぐに使用できる Go-Live ライセンスがあります。

Answer 2

CodeplexのMatthewAbbottとMyRazorViewEngineを利用します。次のことができます。モデルやレイアウトページはサポートされていませんが、このルートを選択した場合は正しい方向に進むことができます。率直に言って、時間の準備ができたらMVC3にアップデートします。このコードは、 http：//buildstarted.com/2010/11/22/making-your-own-viewengine-with-markdown/の私のブログ投稿に基づいています。

global.asaxに次の行を追加する必要があります。

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

両方のエンジンが必要な場合を除いて、その場合は削除するだけですClear()

Answer 3

RazorはMVC 3用です

Answer 4

MVC Razor エンジンを入手し、その使用方法を学ぶ最良の方法は、Scot Gu から入手することです。Razor プロジェクト全体の第一人者。彼のブログ投稿http://weblogs.asp.net/scottgu/archive/2010/10/22/asp-net-mvc-3-layouts.aspx は非常に簡単に理解でき、最初から足場プロセスを管理する方法を教えてくれます。 VS のパッケージ マネージャー コンセル。
