FSharp.Core.sigdata没有发现一起FSharp.Core [英] FSharp.Core.sigdata not found alongside FSharp.Core

问题描述

我试图使用F＃的ASP.NET MVC应用程序。我的一个控制器动作发送一个F＃列表视图，所以我写的：

I'm trying to use F# for an ASP.NET MVC application. One my controller actions sends an F# list to the view, so I write:

<%@ Page Language="C#" Inherits="ViewPage<FSharpList<int>>" %>

当然，对于这个工作，我必须 Microsoft.FSharp.Collections 添加到的命名空间在我的web.config 元素：

<add namespace="Microsoft.FSharp.Collections"/>

和增加 FSharp.Core 的引用，在的组件元素：

and add a reference to FSharp.Core, in the assemblies element:

<add assembly="FSharp.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

只要我添加此程序集的引用，每个视图（无论它使用F＃类型或没有）失败，此错误：

As soon as I add this assembly reference, every view (whether it uses an F# type or not) fails with this error:

错误FS1221：FSharp.Core.sigdata没有发现一起FSharp.Core

error FS1221: FSharp.Core.sigdata not found alongside FSharp.Core

我可以变通的作法是没有我的任何意见F＃特定类型的，但什么是此错误的原因是什么？此外，哪来的 FSharp.Core.sigdata ？这不是我的GAC，我不能在任何地方找到它。

I can work around this by not having any F# specific types in my views, but what's the reason for this error? Also, where's FSharp.Core.sigdata ? It's not in my GAC and I can't find it anywhere.

推荐答案

您将与参考大会找到它，因为sigdata和optdata是设计时的东西（但我猜codeDOM需要他们吗？）例如：

You'll find it with the Reference Assemblies, as sigdata and optdata are design-time things (but I guess CodeDom needs them too?), e.g.:

C:\Program Files\Reference Assemblies\Microsoft\FSharp\2.0\Runtime\v2.0\FSharp.Core.dll
C:\Program Files\Reference Assemblies\Microsoft\FSharp\2.0\Runtime\v2.0\FSharp.Core.optdata
C:\Program Files\Reference Assemblies\Microsoft\FSharp\2.0\Runtime\v2.0\FSharp.Core.sigdata

如果您复制旁边FSharp.Core该应用程序使用的，它可能会工作。

If you copy those next to the FSharp.Core that the app is using, it will probably work.
