Custom object with a System.Web.Security.MembershipUserCollection property - "implement a default accessor" error

Custom object with a System.Web.Security.MembershipUserCollection property - "implement a default accessor" error

I'm tryng to return a custom object that contains a collection of
MembershipUsers through a web service however I receive the following
error when trying to return the object through a web method:

You must implement a default accessor on
System.Web.Security.MembershipUserCollection because it inherits from
ICollection.

The error appears when trying to load the WebService.asmx file. The
code builds fine.

There are quite a few posts about how to resolve this problem however
they all seem to pertain to custom collections. I am using the
MembershipUserCollection and I don't feel that I have the ability to
change how the 'out-of-the-box' version works.

Does anybody know how to resolve this?

Thanks, Justin.

ASP.NET 2.0

Here is the code for the object:

WebService.cs

using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using Demo.Content;

///

/// Summary description for ResortsService
///

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class ResortsService : System.Web.Services.WebService
{
public WebService()
{
//Uncomment the following line if using designed components
//InitializeComponent();
}

[WebMethod]
public Article GetArticle()
Article article = new Article();
return article;
}

Article.cs
using System.Collections.Generic;
using System.Text;

namespace Demo.Content
[Serializable]
public class Article
private int articleID;
private string title;
private System.Web.Security.MembershipUserCollection authors;

public Article()
{ }

#region Members

public int ArticleID
{
get { return this.articleID; }
set { this.articleID = value; }
}

public System.Web.Security.MembershipUserCollection Authors
get { return this.authors; }
set { this.authors = value; }

public string Title
get { return this.title; }
set { this.title = value; }

#endregion

Thanks for the reply Tasos.

I've solved the problem by implementing my own typed collection that
wraps the System.Web.Security.MembershipUserCollection.

Cheers.
