First, we have to install some .NET supported components.

1. Open Server Manager on Windows Server 2016 and click on the Manage menu. Once in there, click on Add Roles and features.
2. Click on Next until you get the Select server roles wizard. Follow the exact route highlighted in this figure:

3. Expand Application Development. You have to select .NET Extensibility 3.5, .NET Extensibility 4.6, ASP, ASP.NET 3.5, ASP.NET 4.6, ISAPI Extensions, and ISAPI Filters.
4. Click on Next to finish. Now let's go on and upload the .NET framework web pages we created for demo purposes.

5. Open IIS Manager, click on Default Web Site, and you will see this screen:

6. In the Actions pane, you have to click on Basic Settings... and check which version of the application pool is associated with the default web site.

7. We have selected DefaultAppPool. Click on the Select... button; you'll see the screen shown in the next figure. Select DefaultAppPool from the dropdown and click on the OK button to finish the pool section.

8. Right-click on Default Web Site, click on Explore, which is in the top-right corner or can be called using the context menu of Default Web Site in the left-hand panel, as highlighted in the next figure. You will get the wwwroot directory, where you have to upload .NET web files.

9. We have created ASP.NET v4.0 files, which we need to paste in the wwwroot folder, as shown here:

10. Here, we've uploaded the .NET application files we created for testing and demo purposes. We will test the application in the last recipe of this chapter later.
