Xamarin.Mac

Mono TLS Deprecation: This version of Xamarin.Mac (C9) is the last one to ship with the optional Mono (managed) SSL/TLS provider. This old provider only supports the SSLv3 and TLSv1 standards, which several servers don't support anymore. Support for the newer TLSv1.1 and 1.2 is only available using the newer AppleTLS provider. This new provider is already used, by default, when building applications (since C7).

Requirements

  • The latest features and API requires Xcode 8.1 and the bundled macosx10.12 SDK;
  • Apple Xcode 8.0 requires a Mac running macOS 10.11 (El Capitan) or 10.12 (Sierra).

What's New

The Xamarin.Mac 3.0 release includes the new APIs that Apple added in the latest SDK (macosx10.12) shipped with Xcode 8.

Please note that the new MediaPlayer framework was changed to 64-bit only.

This release is built upon our open sourced SDK, using the cycle9 branch, and based on Mono 4.8.0.

New NSUrlSessionHandler implementation

A new implementation of NSUrlSessionHandler was contributed by Nick Berardi. The new version offers the same features as the previous one but requires less memory and, by reusing it, less time spent in the garbage collector;

Other Enhancements

  • String optimizations inside the binding generator, i.e. bmac, makes it 10% faster than previous releases;
  • Additional caching in the registrar makes it about 4% faster than previous releases;
  • Several fixes to allow the use of msbuild over xbuild in many cases. Applications using the Xamarin.Mac 4.5 Target framework can not use xbuild yet due to this bug.
