Windows 10

I've found a way to retrieve the Text Scaling Factor, without installing any Nuget packages. The idea is to obtain the value directly from the registry.

var userKey = Microsoft.Win32.Registry.CurrentUser;
var softKey = userKey.OpenSubKey("Software");
var micKey = softKey.OpenSubKey("Microsoft");
var accKey = micKey.OpenSubKey("Accessibility");

var factor = accKey.GetValue("TextScaleFactor");`

Depending on whether you target .NET 5 or an earlier version, you should either set the TargetFramework to net5.0-windows10.0.* or install the Microsoft.Windows.SDK.Contracts NuGet package as described here.

You can then use the Windows.UI.ViewManagement.UISettings.TextScaleFactor property:

double factor = new UISettings().TextScaleFactor;
