return Tuple to js in view

Question

Tried using c# 7 Tuples like

public (string, bool) ProcessForm([FromBody]Dictionary<string,string> contactFormRequest)

But I get the error "CS1031: Type expected". I guess this isn't supported yet.

Then I tried

public Tuple<string, bool> ProcessForm([FromBody]Dictionary<string,string> contactFormRequest)
    {
        var message = "test";
        var result = true;
        var tuple = new Tuple<string, bool>(message, result);
        return tuple;
    }

This gives no error, but then I cannot pick it up in the view file

function handleResult(data) {
    $("#custommessages").html(data.Item1);
}

$2sxc(@Dnn.Module.ModuleID).webApi.post("Form/ProcessForm", {}, newItem, true).then(handleResult);

This outputs nothing.

If I return a simple string from the controller, "data" picks it fine.

How do you pick up the values from a Tuple return?

Why not create a POCO class for serialization:

public class SomeResult
{
    public string Message{get;set;}
    public bool Result{get;set;}
}

then

public SomeResult ProcessForm([FromBody]Dictionary<string,string> contactFormRequest)
{
    var message = "test";
    var result = true;
    return new SomeResult{Message = message, Result = result};
}
