Deploy or Host ASP.NET Core web application in IIS

Dear folks,

Today I am going to explain the process of deploying the ASP.NET Core web application in IIS (Internet Information Services) web server.

Pre-requsites

ASP.NET Core Runtime Hosting Bundle
Navigate to https://dotnet.microsoft.com/download/dotnet-core/current/runtime
Download Hosting Bundle to deploy [ASP].NET Core applications on a server

Application configuration

To make sure the application deploys and works with IIS, you should add the following while creating the web host.

WebHost.CreateDefaultBuilder(args)
.UseKestrel()
.UseIISIntegration()
.UseStartup();

Where Kestrel hosts the application and IIS will be acting as a reverse proxy.

Publish the application

After doing the changes, publish the application to a folder as self-contained as you no need to bother about the server for all the application dependencies.

Web Configuration

In Web.config, remove the following content

hosting="In Progress"

Copy files to IIS location
Create a website folder in IIS wwwroot folder
Copy the publish folder to the website folder
Example: C:\inetpub\wwwroot\website

IIS Application Pool

Create an application pool in IIS with following configuration

Name:
.NET CLR version: No Managed Code
Managed pipeline mode: Integrated

Website Configuration

Right click on the website and select "Add Application"
Give the following details

Alias:
Application Pool: Select above created application pool from list
Physical path: Select the above created website path

Example: C:\inetpub\wwwroot\website

Restart IIS

Once you have completed all the steps, perform the following to make sure everything is in sync.
Open powershell in administrator mode
Run the following commands

net stop was /y
net start w3svc

Test

Browse to the URL, you should be able to get the web pages.
