Xamarin 9.2.x Releases
The Xamarin.iOS 9.2 series upgrades the Mono stack from Mono 4.0 to Mono 4.2 One of the major themes in Mono 4.2.xx series is the continued adoption of Microsoft's open sourced .NET code to improve the conformance, speed and memory usage of our stack.
Xamarin.iOS 9.2 is the successor of 9.0 which introduced support for iOS 9 API and Xcode 7.
Due to non-backward compatible changes in Xcode7.x toolchain this version of Xamarin.iOS is only supported when used with Xcode 7.x or later. This indirectly means the oldest version of iOS that applications can be directly deployed (on devices) is iOS 6.
Visual Studio: New Mac Build Agent
We have rewritten the Mac Build agent that Visual Studio uses to connect to.
The user experience is vastly superior. Not only because it is now easier, more convenient and more reliable to link your Windows and Mac computers, but because we have addressed many of the fundamental design limitations, shortcomings and bugs from our previous implementation. This means more reliable builds, debugging and runs.
We have replaced our pairing and authentication system with one powered by SSH, which now encrypts all data transfers and uses the MacOS provided SSH server as the mechanism to connect your Windows and Mac computers.
WCF available for every license level
It is now possible to use System.ServiceModel.dll and System.ServiceModel.Web.dll assemblies with the Starter and Indie licenses.
Code Generation Optimizations
When compiling with LLVM, Xamarin.iOS will no longer generate intermediate files, and instead will generate object code directly. This allowed us to generate more efficient code (in some large application scenarios, LLVM produced binaries are 3% smaller) and slightly improved build times.
- [insights] iOS apps fails to connect to debugger when Xamarin.Insights is enabled. In Forms templates, Xamarin.Insights is enabled by default [#34885]
