We're excited to announce our seventh preview release for .NET 11!

Note

  • Xcode 26.6 is required with this release. Xcode 26.6 requires macOS 26.2+.

These are the base SDKs that add support for the platforms in question. For MAUI (which is built on top of our SDKs), visit: https://learn.microsoft.com/dotnet/maui/.

This release consists of the following versions:

Full release notes: .NET 11 release notes
Known issues: Known issues in .NET 11

Installation

You can use workload set version 11.0.100-preview.7.26410.2 in order to install these versions of the SDKs,
please make sure to be using the sixth preview of the .NET SDK 11.0.100 before issuing the dotnet workload install command below. You can validate your installed dotnet version using dotnet --version do make sure it shows 11.0.100 or greater before proceeding.

dotnet workload install <workload id(s)> --version 11.0.100-preview.7.26410.2

Available workload ids

Example command installing all listed workloads.

dotnet workload install ios tvos macos maccatalyst maui android --version 11.0.100-preview.7.26410.2

You can use dotnet workload --info to validate the workload versions installed in your system.

New features

CoreCLR

We've switched to using CoreCLR as the runtime for iOS, tvOS and Mac Catalyst (it's been the runtime for macOS since .NET 6).

Most apps will see:

  • Smaller app size.
  • Faster launch and runtime execution.
  • Faster builds, both for debug and release.

We're looking for testers to ensure everything works as expected - using CoreCLR should be a drop-in replacement.

Please test your applications and report any issues, either if something doesn't work, or if app size or runtime performance is worse.

Known issues

Debugging doesn't work with ReadyToRun

There's an incompatibility between the debugger and ReadyToRun, causing the app to crash when launched with the debugger.

The workaround is to disable ReadyToRun in the project file:

<PropertyGroup>
    <PublishReadyToRun>false</PublishReadyToRun>
</PropertyGroup>
