How to load assembly files using Edge.js when hosting the app in iisnode

Question

Is it possible to use edge.js with an application which is hosted on iisnode. A simple inline code like this-

var hello = edge.func(function () {
    /*
    async(input) => {
      return ".NET welcomes " + input.ToString();
    }
    */
});

works properly when the server.js file is handled using iisnode. But in case the edge proxy func is using an assembly file, we need to set EDGE env variables like EDGE_USE_CORECLR and EDGE_APP_ROOT. How do we set these variables in iisnode?
