 > 
 > Using a lower Visual Studio version (like VS2019) is possible, but it is not recommended as you need to downgrade **WindowsAppSDK** via *NuGet* to **WindowsAppSDK 1.1.5** or **WindowsAppSDK 1.2-preview2** before building. This has an increased risk of breaking the application and as such, no support will be provided for this method. **This is not recommended for beginner users.**
