Framework for the restaurant application and server using .NET 4.5 C# and Entity Framework 6+

Restaurant Management Application Framework

Notes

Look into using iPod touch as a touch screen device

Libraries

Data - Contains the data models and is used by every application

DataAccess - Contains mapping for Entity Framework and Data context

Listeners - Packet listeners for the TCP side of the server

Service - provides access to the data used by the web site and server

Network - provides applications with access to the framework through serialiazable packets

Server - Main application for hosting, can be installed as a console application or a web service

ServiceHost - Used for hosting web services with IIS (Doesn't allow TCP)

Web - ASP.NET Web site

Android - Android application

iOS - iPhone/iPad application

Windows - Windows phone/tablet application

Common - A library of helpers classes and extensions

Generic WCF Service

Use ServiceHost to host the web services in the server, example:

// Host the service within this EXE console application. 
public static void Main()
{
  using (ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService)))
  {
    try
    {
      // Open the ServiceHost to start listening for messages.
      serviceHost.Open();

        // The service can now be accessed.
      Console.WriteLine("The service is ready.");
      Console.WriteLine("Press <ENTER> to terminate service.");
      Console.ReadLine();

      // Close the ServiceHost.
      serviceHost.Close();
    }
    catch (TimeoutException timeProblem)
    {
      Console.WriteLine(timeProblem.Message);
      Console.ReadLine();
    }
    catch (CommunicationException commProblem)
    {
      Console.WriteLine(commProblem.Message);
      Console.ReadLine();
    }
  }
}

//http://www.codeproject.com/Articles/650869/Creating-a-Self-Hosted-WCF-Service
// Create the ServiceHost.
using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))
{
    // Enable metadata publishing.
    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
    host.Description.Behaviors.Add(smb);

    // Open the ServiceHost to start listening for messages. Since
    // no endpoints are explicitly configured, the runtime will create
    // one endpoint per base address for each service contract implemented
    // by the service.
    host.Open();

    Console.WriteLine("The service is ready at {0}", baseAddress);
    Console.WriteLine("Press <Enter> to stop the service.");
    Console.ReadLine();

    // Close the ServiceHost.
    host.Close();
}

Fix this error: The communication object, System.ServiceModel.ServiceHost, cannot be used for communication because it is in the Faulted state. Run as a fucking admin... update the manifest

~~The server can be hosted as an .exe or a windows service which will start and stop when the computer is shutdown and restarted.~~

~~Butcher this in the App.Config to set up the service correctly~~ All the hosting is done neatly in code not through a config file. todo: maybe add own simpler config file once serialisation class has been fixed

EF Notes

[MaxLength(100, "{0} can have a max of {1} characters")]
public string Address { get; set; }

Will output the following if it is over the character limit: "Address can have a max of 100 characters"

The placeholders I am aware of are:

{0} = Property Name
{1} = Max Length
{2} = Min Length

Notes

Use WCF for data access and use websockets for push notifications such as updates and new data. This can be loosely based on the Network library. Or use SingalR: http://signalr.net/
