Describe the bug
When using Metrowindow in a dotnet core 3.1 wpf project, I get an IO exception:

System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Management, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.'

To Reproduce

1. Create a new WPF .net core 3.1 project
2. Install MahApps
3. Change MainWindow to a MetroWindow.
4. Run project

Expected behavior
Normal execution

Environment(please complete the following information):

• MahApps.Metro version v1.6.5
• OS: Win10 1903
• Visual Studio 2019 16.4.1
• .NET Framework Core 3.1

** Additionally ***
ControlzEx has removed the dependency in v4.0.0.

@JorundMartinsen v1.6.5 does not support .NET Core 3.0 or 3.1. If you need this then use the latest alpha version (but keep in mind, there are a lot of breaking changes inside).
