Windows Phone 7 UserExtendedProperties

After being directed here: http://msdn.microsoft.com/en-us/library/microsoft.phone.info.userextendedproperties.getvalue%28v=VS.92%29.aspx

I tried the following code

You need to remove 1 from the calculation of your length check to account for the substring operation working on a zero based index:

 if (anid != null && anid.ToString().Length >= (ANIDLength + ANIDOffset - 1))

This works on my machine:

private string GetAnid()
{
    object anidValue;

    int ANIDLength = 32;
    int ANIDOffset = 2;

    if (UserExtendedProperties.TryGetValue("ANID", out anidValue))
    {
        if (anidValue != null && anidValue.ToString().Length >= (ANIDLength + ANIDOffset - 1))
        {
            return anidValue.ToString().Substring(ANIDOffset, ANIDLength);
        }
        else
        {
            return "???";
        }
    }
    else
    {
        return "???";
    }
}
