Could not load file or assembly 'FSharp.Core, Version=4.0.0.0, ...'

[moodmosaic]

The following exception is thrown on Windows 8.1 with Visual Studio 2013 installed:

...\node_modules\edge\lib\edge.js:143
    return edge.initializeClrFunc(options);
                ^

Is it possible to supply an assembly binding redirection to edge-fs with an app.config file?

You should be able to specify assembly redirects in node.exe.config next to node.exe.

I specified the following assembly binding redirect in node.exe.config next to node.exe:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="FSharp.Core"
                          publicKeyToken="b03f5f7f11d50a3a"
                          culture="neutral"/>
        <bindingRedirect oldVersion="4.0.0.0"
                         newVersion="4.3.1.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

It doesn't seem to work though. Now I get I slightly different message:

H:\Projects\edge-fs-sample\node_modules\edge\lib\edge.js:149
    return edge.initializeClrFunc(options);
                ^

Even if I try with FSharp.Core, Version=4.3.0.0 in the assembly redirect I get the same message.

That error sounds like you only have F# 3.1 installed and its looking for FSharp.Core 4.3.0.0 in the GAC which is not included with F#3.1

Im not sure what versions of VS you have installed. I don’t think FSharp.Core 4.3.0.0 is installed with VS2013.

Hm... After doing that I got Unable to build Dynamic Assembly, no assembly output:
