问题
I've been poking around with the fsharp compiler source code to try to build a wp7 version of FSharp.Core (FSharp.Core for Windows Phone 7.1 and F# 3.0), and at one point I gave up and started trying to make the portable version work with wp7 instead. I added the FX_NO_STRUCTURAL_EQUALITY define to the portable-net4+sl4+wp71+win8 target framework, which seems to what's causing it to not work at runtime, and tried to replace the FSharp.Core.dll in C:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\3.0\Runtime\.NETPortable with my custom version. But I get this errors when compiling in Visual Studio:
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. ".NETPortable,Version=v4.0,Profile=Profile47". To resolve this problem, either remove the reference "FSharp.Core" or retarget your application to a framework version which contains "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089". C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets 1578 5 FSharp.Data.Portable

The problem is that the portable FSharp.Core that comes with VS2012 depends on the portable 2.0.5.0 versions of mscorlib.dll, System.dll and System.Core.dllthose assemblies, but the one I compile from source depends on the non-portable 4.0.0.0 versions. Has anyone built the portable version successfully from source?
回答1:
What you could do is add:
<OtherFlags>$(OtherFlags) --simpleresolution -r:"pathToTheCorrectmscorlib/mscorlib-runtime.dll" </OtherFlags>
to the FSharp.Source.Targets file. Do this right file after the <DefineConstants> elements. This should cause the compilation phase to use the version of mscorlib that you specify rather than the default version specified by the msbuild target. (Obviously replace pathToTheCorrectmscorlib/mscorlib-runtime.dll with the correct one :) )

Got the portable-net4+sl4+wp71+win8 target compiling to Profile88 from F# source after a couple of changes https://github.com/ovatsus/fsharp
Still need to thoroughly test at runtime, though
