Host and Publish .Net Core 6 Web API Application on IIS Server

We are going to discuss how to host and publish the.NET Core 6 Web API on the IIS Server.

Introduction

Basically, Internet Information Service (IIS) is the flexible and general-purpose web server provided by Microsoft that will be run on Windows and used to serve requested files.

Required Tools

• IIS Manager
• .NET Core SDK 6
• Visual Studio 2022

Let’s start,

Step 1

Create a new .NET Core Web API Project.

Step 2

Configure your new project.

Step 3

Provide additional information like .NET Framework Version, Open API, and HTTPS.

Step 4

Project Structure.

Step 5

Create the Product Controller, add one endpoint inside that class, and also check other files that are created by default.

using Microsoft.AspNetCore.Mvc;
namespace WebAPI.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class ProductsController : ControllerBase
    {
        [HttpGet]
        [Route("list")]
        public IDictionary<int, string> Get()
        {
            IDictionary<int, string> list = new Dictionary<int, string>();
            list.Add(1, "IPhone");
            list.Add(2, "Laptop");
            list.Add(3, "Samsung TV");
            return list;
        }
    }
}

Program.cs file

var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment() || app.Environment.IsProduction())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}
app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();
app.Run();

Here also, you can see that we configure the HTTP request pipeline for both the development and Production environments.

WebAPI.csproj file

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
  </ItemGroup>
</Project>

launchSetting.json file

{
  "$schema": "https://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:11254",
      "sslPort": 44315
    }
  },
  "profiles": {
    "WebAPI": {
      "commandName": "Project",
      "dotnetRunMessages": true,
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:7047;http://localhost:5047",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

Step 6

Run your application and hit the API endpoint using Swagger UI.

Step 7

Check if all IIS Services are running on your system properly or not. If not, then open the control panel, go to Program and Features, and click on Turn Windows Feature on or off.

Apply the changes as I showed you in the above image, click on Apply, and then restart your computer.

Step 8

After restarting your computer, you will see IIS Manager in the search box. Open it.

Now, check your running IIS using localhost in the browser.

Step 9

Install ASP.NET Core 6.9 Runtime — Windows hosting bundle installer.

Step 10

Now, we are going to publish our application for that, right-click on WebAPI Project and click on Publish.
