Ehkä hieman vanhentunut, mutta sinun pitäisi ehkä katsoa tätä viestiä.

Razor pystyy toimimaan itsenäisesti, joten johdotus on täysin mahdollista hankkia itse. Tarvitseeko sinun .NET4: ää käyttää vai ei, en ole 100% varma. Toisessa huomautuksessa MVC3 on RC-tilassa ja sillä on Go-Live -lisenssi, jonka avulla voit teknisesti alkaa käyttää nyt ja kun RTM osuu (pian) vain päivittää.

Hyödyntämällä Matthew Abbottin ja My Razor View Engineä Codeplexiltä. Voisit tehdä seuraavat. Se ei tue malleja tai asettelusivuja, mutta se vie sinut oikeaan suuntaan, jos päätät mennä tällä reitillä. Suoraan sanottuna haluaisin vain päivittää MVC 3: een, kun aika on valmis. Tämä koodi perustui blogikirjoitukseeni osoitteessahttp://buildstarted.com/2010/11/22/making-your-own-viewengine-with-markdown/

Sinun on lisättävä seuraava rivi global.asax-tiedostoon:

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

ellet halua molempia moottoreita, jolloin vain poistaClear()

Paras tapa hankkia MVC Razor -moottori ja oppia käyttämään sitä on Scot Guilta! Koko Razor-projektin Guru. Hänen blogikirjoituksensahttp://weblogs.asp.net/scottgu/archive/2010/10/22/asp-net-mvc-3-layouts.aspxon erittäin helppo seurata ja opettaa rakennustelineiden hallintaa VS: n Package Manager Conselista.
