使用 FSharp.Core.dll 的自定义版本

我一直在研究 fsharp 编译器源代码，尝试构建 FSharp.Core 的 wp7 版本（适用于 Windows Phone 7.1 和 F# 3.0 的 FSharp.Core https://stackoverflow.com/questions/14694577/fsharp-core-for-windows-phone-7-1-and-f-3-0），有一次我放弃了，开始尝试让便携式版本与 wp7 一起使用。我添加了FX_NO_STRUCTURAL_EQUALITY定义为portable-net4+sl4+wp71+win8目标框架，这似乎导致它在运行时无法工作，并尝试替换中的 FSharp.Core.dllC:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\3.0\Runtime\.NETPortable与我的自定义版本。但在 Visual Studio 中编译时出现此错误：

Warning 1   The primary reference "FSharp.Core" could not be resolved because it has an indirect dependency on the framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which could not be resolved in the currently targeted framework.

问题是VS2012附带的可移植FSharp.Core依赖于可移植2.0.5.0版本的mscorlib.dll、System.dll和System.Core.dll这些程序集，但我从源代码编译的那个依赖于不可移植的4.0.0.0版本。有人从源代码成功构建了便携式版本吗？

你可以做的是添加：

<OtherFlags>$(OtherFlags) --simpleresolution -r:"pathToTheCorrectmscorlib/mscorlib-runtime.dll" </OtherFlags>

to the FSharp.Source.Targets文件。之后执行此正确的文件<DefineConstants>元素。这应该会导致编译阶段使用以下版本mscorlib您指定的版本而不是 msbuild 目标指定的默认版本。 （显然替换pathToTheCorrectmscorlib/mscorlib-runtime.dll与正确的一个:)）
