You guessed it. The WPF version of Theine is now open source at GitHub!
The following tweet caught my attention. Turns out I was tagged in it.
Being the gentleman that I am, I replied.
2 days later, I did not clean up the repository, but did split off the core app code into its own repository.
Head over to hannesbarbez/BarbezDotEu.Theine.WPF: Home of the WPF version of the Theine app from the Microsoft Store. (github.com) to get the goods. Or to file an issue. You’re welcome.
