F# Global.asax -- language not supported?

Im trying to write a simple F# ASP.Net MVC app

Ive added the Global.asax as follows

<%@ Application Inherits="WebApplication.Core.Global" Language="F#" %>

then in a separate referenced assembly I 开发者_开发问答have

namespace WebApplication.Core  with a type Global() = etc

Getting a 'F#' is not a supported language.

Am I not able to do this?

Thanks

You need to add something like below in web.config:

<compiler language="F#;f#;fs;fsharp"
          extension=".fs"
          warningLevel="4"
          type="Microsoft.FSharp.Compiler.CodeDom.FSharpAspNetCodeProvider,
            FSharp.Compiler.CodeDom, Version=1.9.6.2,
            Culture=neutral,
            PublicKeyToken=a19089b1c74d0809">
  <providerOption name="CompilerVersion" value="v3.5" />
  <providerOption name="WarnAsError" value="false" />
</compiler>
