Pre-release

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

Note

  • Xcode 26.5 is required with this release. Xcode 26.5 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.5.26309.3 in order to install these versions of the SDKs,
please make sure to be using the fifth 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.5.26309.3

Available workload ids

Example command installing all listed workloads.

dotnet workload install ios tvos macos maccatalyst maui android --version 11.0.100-preview.5.26309.3

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

New features

(Experimental) CoreCLR

We've added support for using CoreCLR as the runtime for iOS, tvOS and Mac Catalyst, and this is now the default runtime.

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 (it's been the runtime on macOS since .NET 6)

To enable, add this to your project file:

<!-- Use CoreCLR on iOS -->
<PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">
    <UseMonoRuntime>false</UseMonoRuntime>
</PropertyGroup>

<!-- Use CoreCLR on tvOS -->
<PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tvos'">
    <UseMonoRuntime>false</UseMonoRuntime>
</PropertyGroup>

<!-- Use CoreCLR on Mac Catalyst -->
<PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">
    <UseMonoRuntime>false</UseMonoRuntime>
</PropertyGroup>

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

Known issues (these will be fixed in a future preview):

  • Debugging isn't supported yet
  • Some runtime diagnostics features aren't fully functional yet

This is an experimental feature and not intended for production use yet.

If you find that CoreCLR doesn't work, you can keep using Mono by adding this to your project file:

<PropertyGroup>
    <UseMonoRuntime>true</UseMonoRuntime>
</PropertyGroup>

  • This release adds Xcode 26.4 build support, no new APIs have been added.

This is a servicing release to the previous .NET 9 release.

Note: these are the base SDKs that add support for the platforms in question, for MAUI (which is built on top of our SDKs), go here instead: https://docs.microsoft.com/en-us/dotnet/maui/.

Versions

This release consists of the following versions:

Installation

You can use workload set version 9.0.313.1 in order to install these versions of the SDKs.

Please make sure to be using the latest .NET SDK 9.0.313 before issuing the dotnet workload install command below. You can
validate your installed dotnet version using dotnet --version do make sure it shows 9.0.313 or greater before proceeding.

dotnet workload install <workload id(s)> --version 9.0.313.1

Available workload ids

Example command installing all listed workloads.

dotnet workload install ios tvos macos maccatalyst maui android --version 9.0.313.1

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

What's Changed

  • [release/9.0.1xx] Update build to use Xcode 26.4 no new API bindings by @dalexsoto in #25010

Sharpie 26.4.0.212 Pre-release
Pre-release

We're excited to announce the second preview release of a major upgrade to Objective-Sharpie!

Main changes

  • Open source
  • Shipped as a .NET tool
  • Updated to use a much newer version of Clang (21), which also means it's possible to use the latest versions of Xcode.
  • Updated to use ClangSharp instead of a custom clang integration.

Our documentation has been updated as well: https://learn.microsoft.com/dotnet/maui/ios/objective-sharpie/

Installation

Install like this:

$ dotnet tool install -g Sharpie.Bind.Tool
You can invoke the tool using the following command: sharpie
Tool 'sharpie.bind.tool' (version '26.4.0.212') was successfully installed.

or update like this:

$ dotnet tool update -g Sharpie.Bind.Tool
Tool 'sharpie.bind.tool' was successfully updated from version '26.3.0.11' to version '26.4.0.212'.

Important

If the old sharpie is still installed, it might be found when executing sharpie:

$ sharpie --version
3.5.126-e5d8c166 # this is the old sharpie
sharpie --version
dotnet-sharpie 26.4.0.212 # this is the new sharpie

Running this should make the new sharpie take precedence (this won't actually uninstall the old sharpie, just remove the convenience script in "/usr/local/bin/sharpie"):

$ sudo rm -f /usr/local/bin/sharpie

Usage

Use it to bind a framework like this:

$ sharpie bind --framework path/to/my.framework --output output-directory

For more information see https://learn.microsoft.com/dotnet/maui/ios/objective-sharpie/.

Please test and file any issues here!

What's Changed

  • [sharpie/xtro] VersionTuple.IsEmpty is incorrect, so use an extension property with the correct implementation. by @rolfbjarne in #25034
  • [sharpie] Add --custom-delegates option to generate named delegates instead of Func<>/Action<> by @rolfbjarne in #24975
  • [sharpie] Add --deepsplit option to split bindings into one file per source header by @dalexsoto in #24883
  • [sharpie] Add support for visionos_app_extension availability platform. Fixes #18098. by @rolfbjarne in #24828
  • [sharpie] Bump ClangSharp to v21.1.8.3 by @dalexsoto in #25004
  • [sharpie] Fix --scope path matching by @dalexsoto in #24882
  • [sharpie] Fix platform type mapping for types inside generic type arguments. Fixes #24892. by @rolfbjarne in #24911
  • [sharpie] Prefer standard protocol interfaces over [Model] classes in type mapping by @rolfbjarne in #24913

.NET 11.0.1xx Preview 3 (11588) Pre-release

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

Note

  • Xcode 26.3 is required with this release. Xcode 26.3 requires macOS 15.6+.

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.3.26214.1 in order to install these versions of the SDKs, please make sure to be using the third 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.3.26214.1

Available workload ids

Example command installing all listed workloads.

dotnet workload install ios tvos macos maccatalyst maui android --version 11.0.100-preview.3.26214.1

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

New features

(Experimental) CoreCLR

We've added support for using CoreCLR as the runtime for iOS, tvOS and Mac Catalyst.

Most apps will see:

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

We're looking for early testers to ensure everything works as expected - using CoreCLR should be a drop-in replacement (it's been the runtime on macOS since .NET 6)

To enable, add this to your project file:

<!-- Use CoreCLR on iOS -->
<PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">
    <UseMonoRuntime>false</UseMonoRuntime>
</PropertyGroup>

<!-- Use CoreCLR on tvOS -->
<PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'tvos'">
    <UseMonoRuntime>false</UseMonoRuntime>
</PropertyGroup>

<!-- Use CoreCLR on Mac Catalyst -->
<PropertyGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'maccatalyst'">
    <UseMonoRuntime>false</UseMonoRuntime>
</PropertyGroup>

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

Known issues (these will be fixed in a future preview):

  • Debugging isn't supported yet
  • Some runtime diagnostics features aren't fully functional yet

This is an experimental feature and not intended for production use yet.
