ASP.NET MVC 3 @Facebook.LoginButton simple

Эхлээд ~/Views/Web.config доторхи кодыг ийм болгож өөрчилнө. Ингэж байж ASP.NET MVC 3 Razor syntax @Facebook бичиглэлийг танина. Үгүй бол @Microsoft.Web.Helpers.Facebook гэж бичсэн ч болно.

<system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

Index.csHtml код дотор нэг иймэрхүү код бичвэл шууд Login With Facebook харагдана
