How to correctly return .NET dates from ASP.NET MVC to Javascript/JQuery

Question

I've found a million posts about serializing .NET dates to json. Yet, I'm unable to get any of those to work correctly.

Here is my serialzier code so far:

string javascriptJson = JsonConvert.SerializeObject(result, 
   new JavaScriptDateTimeConverter());
return Content(javascriptJson, "application/json");

This returns an unescaped string containing the correct JSON, and looks completely right when viewing it in the browser. (e.g. dates looks like : date: new Date(023198928) and as far as my limited javascript skill goes, that is how it should look like)

However, I can not get JQuery to understand this, either I get back a plain javascript string, or it simply fails, I want the deserialized object.

I've tried both $.get and $.getJSON

Ideas ?

These are not the mothods you are looking for...

jQuery.get():
Retrieve one of the DOM elements matched by the jQuery object.

jQuery.getJSON():
Load JSON-encoded data from the server using a GET HTTP request.

Try jQuery.parseJSON() instead:
Takes a well-formed JSON string and returns the resulting JavaScript object.

Tried jQuery.parseJSON() but it throws and complains about unexpected token, however var res = eval(data); works correctly

Plain JavaScript eval() - Nice! It seems I didn't see the wood for the trees. Again... It's strange that parseJSON() fails, though. If you have the time, you should find out why - and post it here to satisfy my curiosity ;-)

It turns out that even though the response from my service is valid javascript, it is not valid Json.

You can not return "{ date : new Date(24342) }" as it opens up for script injection I guess. I reverted back to the standard .NET Json serializer and simply parsed the "\Date(343)\" that it returns..
