        static void Main(string[] args)
        {
            // TODO  Change the path to the appropriate one for your CSProviderDLL.
            string fileloc = @"C:\SampleDependencies\CSProviderDLL.dll";
            Assembly a = null;
            try
            {
                a = Assembly.LoadFile(fileloc);
            }
