            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            DevExpress.Utils.BindToTypePolicy.QueryAssemblyLoad += BindToTypePolicy_QueryAssemblyLoad;
            Application.Run(new Form1());
        }
        private static void BindToTypePolicy_QueryAssemblyLoad(object sender, DevExpress.Utils.BindToTypePolicy.QueryAssemblyLoadEventArgs e) {
            if (e.AssemblyName.StartsWith("EntityFramework", StringComparison.OrdinalIgnoreCase)) {
                // Loads a specific assembly version distributed with the application.
                var appDirectory = Path.GetDirectoryName(typeof(Program).Assembly.Location);
                string path = Path.Combine(appDirectory, @"..\\Lib", "EntityFramework.dll");
                e.Assembly = Assembly.LoadFrom(path);
            }
        }
    }
