It has been just over 3 months since our 4.0 release, and we’ve used that time to focus on performance as well as bringing the latest .NET 6 and even .NET 7 innovation to Uno Platform. By simply updating your application to the newest bits you will notice a significant boost to your app performance.

This release packs over 200 new feature requests, bugs, and issues you raised. We welcomed a few great contributions from our community which is now over 210 contributors strong! Thanks for all you bring to Uno Platform.

For more information about the release, read our blog post.

Important note about .NET 6 Mobile support

The current support for .NET 6 Mobile Preview 13 requires VS 2022 17.2 Preview 1 or later, 17.0.x and 17.1.x are not supported, and naturally Uno Platform will face the same constraints. It’s also worth noting that with .NET 6 mobile Preview 14, Microsoft will introduce an additional (and likely final) set of binary breaking changes, and we’ll publish an update to Uno nuget package to align with those changes.

Once you have 17.2 Preview 1 or later installed, use uno-check --preview to setup your environment.

    You can disable this behavior by setting the Uno.FoundationFeatureConfiguration.Runtime.RethrowNativeExceptions config flag to false.
