Use Superscribe.Owin Package in Web API

Introduction

In this article I will use the "Superscribe.Owin" package in the ASP.NET Web API. We use the package for determine what the web framework contributes. Superscribe is a module for the router handler. It is a way to map between the media types and serialiser.

Now for an example.

Step 1

Create an application as in the following:

• Start Visual Studio 2012.
• From the Start window Select "New Project".
• Then select "Installed" -> "Visual C#" -> "Web".

• Select "ASP.NET Empty Web Application".

Step 2

Install a package as in the following:

• Go to the "Tools" menu then select "Library Package Manager" -> "Package Manager Console".
• Now install the following packages:
  
  Install-Package Owin
  Install-Package Microsoft.Owin.Host.SystemWeb
  Install-Package Owin.Types
  Install-Package Owin.Extensions

Step 3

Now install the Superscribe.Owin Package through Nuget Manager.

• Go to the "Tools" menu then select "Library Package Manager" -> "Manage NuGet Package for Solutions".
• In the search box type "Superscribe".
• Then select "Superscribe.Owin" and instal it.

Step 4

There is a class named "Startup.cs".

Add the following code to it:

using Owin;
using Superscribe.Owin;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace SuperOwin
{
    public class Startup
    {
        public void Configuration(IAppBuilder ibuild)
        {
            var Con = new SuperscribeOwinConfig();
            Con.MediaTypeHandlers.Add(
            "text/html",
            new MediaTypeHandler { Write = (rslt, o) => rslt.WriteAsync(o.ToString()) });

            ibuild.UseSuperscribeModules(Con);
        }
    }
}

Step 5

Add a new class as in the following:

• In the Solution Explorer.
• Right-click on the "SuperOwin" project name.
• Select "Add" -> "Class".

Add the folowing code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Superscribe.Owin;
namespace SuperOwin
{
    public class Hello: SuperscribeOwinModule
    {
       public Hello()
           {
             this.Get["/"] = _ => "This is the example of Superscribe Owin:";
             }
    }
}

Step 6

Now in the Web.config file we ensure that it handles the OWIN request:

<appSettings>
<add key="owin:HandleAllRequests" value="true" />
<add key="owin:SetCurrentDirectory" value="true" />
</appSettings>

Step 7

Now execute the application:
