Record with parameterless constructor?

Question

I'm trying to build a web app (ASP.NET MVC3) that uses Entity Framework, and I've once again hit a wall. It throws following exception when trying to run a foreach loop over the collection in the view:

System.InvalidOperationException: The class 'GvG.Entities.News' has no parameterless constructor.

Now is my question, is it possible to somehow define a parameterless constructor on my record type?

My record type at the moment looks like:

type News = { 
    mutable ID:int; 
    mutable Author:string; 
    mutable Title:string; 
    mutable Content:string }

I'm aware of that I can create a class with baking-fields etc. instead, but thats what I'm trying to avoid.

It's an old one, but I stumbled upon similar issue today, and looks like with F# 3.0 you can overcome it with [<CLIMutable>] attribute: http://msdn.microsoft.com/en-us/library/hh289724.aspx

This way you can use your F# immutable records in many scenarios when C# API requires POCO.
