Add the IIS integration to your project

- [Instructor] If you look closely at your program.cs file,…you'll see a call to a method called UseIISIntegration.…This method is provided by an IIS Integration Package…that's automatically installed…in the default ASP.NET Core template.…If you're not using a template,…make sure your project includes…the Microsoft.AspNetCore.Server.IISIntegration…Nougat Package.…What this package does is give ASP.NET Core a hint…that IIS is the reverse proxy in front of the application.…

It doesn't replace Kestrel,…it just allows IIS and ASP.NET Core to work together…on setting ports and reading environment variables.…It seems a little odd at first…to see references to both Kestrel and IIS,…but Kestrel is the actual server here.…The UseIISIntegration line in the program class…doesn't mean your application is tightly coupled to IIS,…or that it's no longer portable,…it's still possible to launch Kestrel directly…or move your application to a Linux server.…Now that we've verified that this package…is installed in the project,…we're ready to deploy this application to IIS.…
