**Avalonia** is ready for **General-Purpose Desktop App Development**. However, there may be some bugs and breaking changes as we continue along into this project's development. > **Note:** The UI theme you see in the picture above is still work-in-progress and will be available in the upcoming Avalonia 0.10.0 release. However, you can connect to our nightly build feed and install latest pre-release versions of Avalonia NuGet packages, if you are willing to help out with the development and testing. See [Using nightly build feed](https://github.com/AvaloniaUI/Avalonia/wiki/Using-nightly-build-feed) for more info.
