.NET version support

This page lists supported .NET versions and C# language versions for different target platforms.

Table of supported versions

Uno 5 and later
Uno 4 and earlier

Platform	Default .NET version	Default C# version	Max .NET version	Max C# version
WebAssembly	.NET 8	12	.NET 9	13
Skia Desktop	.NET 8	12	.NET 9	13
WinAppSDK	.NET 8	12	.NET 9	13
iOS, macOS, Android, Catalyst (.NET Core)	.NET 8	12	.NET 9	13
UWP	.NET Standard 2.0	7.3	.NET Standard 2.0	7.3

Notes

In Uno 5.3, support for .NET 7 has been removed.
In Uno 5.0, support for .NET 6 (iOS, Android, mac Catalyst), Xamarin.Android, Xamarin.iOS, and Xamarin.macOS was removed.
For UWP, it is possible force a higher version of C# using LangVersion in the platform csproj (eg <LangVersion>12.0</LangVersion>), but some language features may not work properly, such as those that depend on compiler-checked types (eg array slicing, init-only properties) or on runtime support (eg default interface implementations). Using PolySharp can help enabling some more recent C# features.

Platform	Default .NET version	Default C# version	Max .NET version	Max C# version
WebAssembly	.NET 6	10	.NET 7	11
Skia (Gtk, Framebufffer, WPF)	.NET 6	10	.NET 7	11
WinAppSDK	.NET 6	10	.NET 7	11
iOS, macOS, Android, Catalyst (.NET Core)	.NET 6	10	.NET 7	11
iOS, macOS, Android (Xamarin)	.NET Standard 2.1	8	.NET Standard 2.1	8
UWP	.NET Standard 2.0	7.3	.NET Standard 2.0	7.3

Notes

For Xamarin.Android, Xamarin.iOS, and Xamarin.macOS, the supported versions depend on the version of Xamarin installed, which is generally tied to the Visual Studio version if you are using Visual Studio.

For UWP, it is possible force a higher version of C# using LangVersion in the platform csproj (eg <LangVersion>12.0</LangVersion>), but some language features may not work properly, such as those that depend on compiler-checked types (eg array slicing, init-only properties) or on runtime support (eg default interface implementations).
