Using 4.7.2 Framework for WPF Project System.NET.HTTP Cannot Be Found

Question

I was originally developing a project using the 4.6.1 Framework however one of the Nuget packages I wanted required the new 4.7.2 Framework to be used. As a result, I upgraded my project, which when attempting to run again and send a HTTP request gave me the error:

System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Net.Http, 
Version=4.2.0.0, Culture=neutral, PublicKeyToken=**********' or one of its
dependencies. The system cannot find the file specified.'

How do I resolve this? (If I downgrade back to 4.6.1 it works, and I've also tried to uninstall and reinstall System.Net while using 4.7.2 Framework)

I did, I mentioned I uninstalled it and then reinstalled it when I upgraded. — Explorex, Nov 28 '18 at 06:15
Yep, I can also see that its in references. However I'm still getting this error — Explorex, Nov 28 '18 at 06:21
Possibly this may be the issue: https://github.com/dotnet/corefx/issues/29622 — Explorex, Nov 28 '18 at 06:25

In app.config change:

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />

to

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.1" />
