I know that question is quite old, but if someone has such problem I suggest such solution:

protected Guid GetNewId()
{
    SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["YourConnectionString"].ConnectionString);
    var query = "select newid()";
    conn.Open();
    SqlCommand com = new SqlCommand(query, conn);
    var guid = new Guid(com.ExecuteScalar().ToString());
    conn.Close();
    return guid;
}

You can get newid from SQL database when your new object is creating. For me it works. :) (but I don't know it is good practice)

How use it:

var myNewGuidValue = GetNewId();
