I've noticed what appears to be a bug in the Visual Studio.NET (1.0
and 2003 versions). If I declare a web method like so:

[WebMethod]
public ArrayList GetMyList()
{
    ArrayList list = new ArrayList()
    list.Add("one");
    list.Add("two");
    return list;
}

If I bind to the above from a client application like so:

ArrayList newlist = mywebservice.GetMyList();

The above fails (sometimes, sometimes it works), the compiler expects
a type of object[] (object array) and not ArrayList. Casting also
fails. I've even tried the following:

[WebMethod]
public object[] GetMyList()
{
    ArrayList list = new ArrayList()
    list.Add("one");
    list.Add("two");
    return list.ToArray();
}

Sometimes it works, sometimes it doesn't work. The later example never
works. Can anyone explain this? Is it a IDE generated code bug?
