Install

You can download and install the latest release from here.

Note: Windows SmartScreen might show you this warning screen. This is because the setup file is not being signed but the app is 100% safe to be run.

Description

I've built this app in my spare time to resolve my frustration with Windows 10 for not having automatic dark theme switcher. This may be included in the next releases of Windows 10 but for now here is Luna!

This is a super lightweight app built using C# and WPF technologies. It creates task schedules for light/dark theme times. There are no running processes in the background and there is not need to start when Windows starts.

3^rd party libraries used:

• Infragistics Metro Light and Dark Theme for WPF
• TaskScheduler
• Extended WPF Toolkit
• ThemeTool.exe - a Windows internal theme testing program used to change the Windows theme

Command line parameters

Parameter	Description
/light	Switches to the light theme based on the saved settings
/dark	Switches to the dark theme based on the saved settings
/update	Silently checks for an update and installs it
/clean	Cleans all task schedules created by the app

Build

Clone and open the solution in Visual Studio. Right-click on the project and click Restore NuGet Packages.

If you want to build the Release configuration and generate the setup executable (which is done automatically by building the Release configuration) you need to download and install Inno Setup. The output setup executable can be found under .extra\Output.

Future plans

As time passes I might add new features (or contributions) to complete an experience that Windows 10 doesn't have (yet).

Contributions

To make this app better for everyone, feel free to contribute with ideas, bug reports or even better: pull requests :)
