Fix F# WinRT Application Verification Problem

When you use Visual Studio 2012 F# portable library, you can run into the application verification problem. Here is the solution for VS2012 installation.

(1)      Add the following code to your portable DLL

 [<assembly:System.Resources.NeutralResourcesLanguageAttribute("en-US")>]  
 do()  

(2)      Go to the project properties for your F# portable DLL and do the following:

a.         Click on Build and set “Configuration” to “Release”

b.         Enter “--staticlink:FSharp.Core” to the “Other flags”

c.         Click on “Build Events”

d.         Set “Run the post-build event” to “When the build updates the project output”

e.         Paste the following text into “Post-build event command line”

 if \"$(ConfigurationName)\"==\"Release\" (  
 "C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\ildasm.exe" /linenum /nobar /out="$(TargetName).il" $(TargetFileName)  
 powershell "$lines = '}','} /*','} */'; $matchCount = 0; $clashCount = 0; filter GetOutput { if ($_ -eq ' } // end of method MatchFailureException::.ctor') { $lines[$matchCount++] } else { if ($_ -eq '  } // end of method Clash::.ctor') { $lines[$clashCount++] } else { $_ } } }; (Get-Content $(TargetName).il) | GetOutput | Set-Content $(TargetName).il"  
 "C:\Windows\Microsoft.NET\Framework\v4.0.30319\ilasm.exe" /dll /debug=opt /quiet $(TargetName).il  
 copy /y $(TargetName).dll ..\obj\Release\  
 )  

        Alternatively, just edit the .fsproj of your portable DLL project and add the following at the end of the first PropertyGroup:

 <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">  
   <OtherFlags>--staticlink:FSharp.Core</OtherFlags>  
  </PropertyGroup>  
  <PropertyGroup>  
   <RunPostBuildEvent>OnOutputUpdated</RunPostBuildEvent>  
   <PostBuildEvent>if \"$(ConfigurationName)\"==\"Release\" (  
 "C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\ildasm.exe" /linenum /nobar /out="$(TargetName).il" $(TargetFileName)  
 powershell "$lines = '}','} /*','} */'; $matchCount = 0; $clashCount = 0; filter GetOutput { if ($_ -eq ' } // end of method MatchFailureException::.ctor') { $lines[$matchCount++] } else { if ($_ -eq '  } // end of method Clash::.ctor') { $lines[$clashCount++] } else { $_ } } }; (Get-Content $(TargetName).il) | GetOutput | Set-Content $(TargetName).il"  
 "C:\Windows\Microsoft.NET\Framework\v4.0.30319\ilasm.exe" /dll /debug=opt /quiet $(TargetName).il  
 copy /y $(TargetName).* ..\..\obj\Release\  
 )  
   </PostBuildEvent>   
  </PropertyGroup>
