In this post, learn about self-hosting and how to Self Hosting Web API the ASP.NET Web API. You won’t need the IIS server for this topic. We use a console program to host the Web API.

Step 1

We start by developing the console application.

The launch of Visual Studio 2012.
“New Project” can be chosen from the Start page.
Choose Installed template->Visual C# from the Templates menu.
Change the name to “Hosting” and choose “Console application.”
On the “OK” button, click.

Step 2

“.Net Framework 4” should be set.

Right-click the project in the “Solution Explorer.”
“Properties” should be chosen.
Choose “.Net Framework 4” from the Destination Folder Drop Down List in the Properties dialogue.

Open a popup to apply the adjustment, then select “Yes.”

Step 3

We determine whether or not the NuGet Package Manager is installed.

Go to the Tools menu.
The “Nuget Package Manager” is installed if the “Library Package Manager” is visible.
It is not installed if “Library Package Manager” is not visible.

For “Nuget Package Manager” installation:

Choose “Extension and Updates” from the “Tools” menu.
Choose “Online” in the “Extension and Updates” dialogue box.
The search term “nuget package management” should be entered.
Choose “Install Nuget Package Manager” to do so.

Step 4

The Web API Self-Host Package is now installed.

Choose “Library Package Manager” -> “Manages Nuget Packages For Solution” from the “Tools” menu.
Type “Microsoft.AspNet.WebApi.SelfHost” in the “Nuget Package Manager” dialogue box.

Click Install after selecting the ASP.NET Web API Standalone Host.

Choose “I Accept” from the menu.

Step 5

Establish the Model class:

“Solution Explorer” is where.
Choose “Hosting” -> “Add” -> “Class” from the context menu when you right-click the project.
Rename the class to “Item” instead.
On the “OK” button, click.

Put the following code in the “Item” Class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Hosting
{
public class Item
{
public int Id { get; set; }
public string Name { get; set; }
public string Category { get; set; }

Step 6

Making a Controller class addition:

“Solution Explorer” is where.
Choose “Hosting” -> “Add” -> “Class” from the context menu when you right-click the project.
Call the class “ItemsController” instead.
On the “OK” button, click.
In the “ItemsController” class, add the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Text;
using System.Web.Http;
namespace Hosting
{
public class Items Controller : ApiController
{
Item[] items = new Item[]
{
new Item { Id = 1, Name = “Apple”, Category = “Fruit” },
new Item{ Id = 2, Name = “Tomato”, Category = “vasitable” },
new Item{ Id = 3, Name = “T-Shirt”, Category = “cloths” }
};
public IEnumerable<Item> GetAllItems()
{
return items;
}
public Item GetItemById(int id)
{
var item = items.FirstOrDefault((i) => i.Id == id);
if (item == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
return item;
}
public IEnumerable<Item> GetItemsByCategory(string category)
{
return items.Where(i => string. Equals(i.Category, category,
StringComparison.OrdinalIgnoreCase));
}
}
}

Step 7

We now Self Hosting Web API.

Open “Program.cs” and enter the following code there:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Http;
using System.Web.Http.SelfHost;
namespace Hosting
{
class Program
{
static void Main(string[] args)
{
var config = new HttpSelfHostConfiguration(“http://localhost:8080”);
config.Routes.MapHttpRoute(
“API Default”, “api/{controller}/{id}”,
new { id = RouteParameter.Optional });
using (HttpSelfHostServer server = new HttpSelfHostServer(config))
{
server.OpenAsync().Wait();
Console.WriteLine(“Press Enter to quit.”);
Console.ReadLine();
}
}
}

Step 8

Use the following to add a new project to this application:

“Solution Explorer” is where.
To start a new project, right-click the project and choose “Add.”
Make the name “Client” instead.

Step 9

With the following, install the “Microsoft ASP.NET Web API Client Library”:

Choose “Extension and Updates” from the “Tools” menu.
Choose “Online” in the “Extension and Updates” dialogue box.
Enter “Microsoft.AspNet.WebApi.Client” in the search box.
Installing it involves choosing the “Microsoft ASP.NET Web API library.”

Step 10

Use the following to add the client’s reference to the “Hosting” project:

Right-click the “Client” project in the “Solution Explorer.”
The “Add reference” option.
Launch the “Reference” dialogue window.
“Projects” is the answer you should select.

So, choose “Ok” from the menu.

Step 11

The “Client” project’s “Program.cs” file should be opened.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Http;
namespace Client
{
class Program
{
static HttpClient client = new HttpClient();
static void Main(string[] args)
{
client.BaseAddress = new Uri(“http://localhost:8080”);
ListAllItems();
ListItem(1);
ListItems(“fruit”);
Console.WriteLine(“Press Enter to quit.”);
Console.ReadLine();
}
static void ListAllItems()
{
HttpResponseMessage resp = client.GetAsync(“api/items”).Result;
//resp.EnsureSuccessStatusCode();
var items = resp.Content.ReadAsAsync<IEnumerable<Hosting.Item>>().Result;
foreach (var i in items)
{
Console.WriteLine(“{0} {1} {2}”, i.Id, i.Name, i.Category);
}
}
static void ListItem(int id)
{
var resp = client.GetAsync(string.Format(“api/products/{0}”, id)).Result;
//resp.EnsureSuccessStatusCode();
var item = resp.Content.ReadAsAsync<Hosting.Item>().Result;
Console.WriteLine(“ID {0}: {1}”, id, item.Name);
}
static void ListItems(string category)
{
Console.WriteLine(“items in ‘{0}’:”, category);
string query = string. Format(“api/items?category={0}”, category);
var resp = client.GetAsync(query).Result;
resp.EnsureSuccessStatusCode();
var items = resp.Content.ReadAsAsync<IEnumerable<Hosting.Item>>().Result;
foreach (var item in items)
{
Console.WriteLine(item.Name);
}
}
}
}

Step 12

Then Run the application now.

Right-click the “Hosting” Project in the “Solution Explorer.”
choose “Set as Start Up project” next.

Press F5 for execution.

Step 13

Use the following to debug the hosting project:

Right-click the project “Client” in the Solution Explorer.a
“Debug” -> “Start new instance” should be selected.
