Embedded Resource missing in Visual Studio 2010 when name ends with "No.xxx"

Question

I've come across a strange behaviour in Visual Studio 2010.

When using embedded resources (files which are added to my C# project and for which the Build Action property is set to Embedded Resource), the files are included in the output assembly as binary data. Listing the resources is straightforward:

class Program
{
    static void Main(string[] args)
    {
        string[] names = typeof (Program).Assembly.GetManifestResourceNames ();

        foreach (var name in names)
        {
            System.Console.Out.WriteLine (name);
        }
    }
}

However, if the embedded resource file name ends with No.xxx (the extension is irrelevant), the file does not show up in the list. I cannot figure out any reason why Visual Studio 2010 would not include such a file. What did I miss?

Note: if I rename the embedded resource file in the solution explorer to something else, then everything works as expected.
