PostSharp Technologies is pleased to announce the release of PostSharp 4.1, the latest version of the #1 compiler extension for .NET, adding support for design patterns and thread safety to C# and Visual Basic.

PostSharp 4.1 focuses on extending the set of supporting platforms by adding Xamarin (both iOS and Android), Visual Studio 2015, Visual Studio Universal Apps to the list of compatible products, and by improving the level of support of Windows 8 and Windows Phone. PostSharp 4.1 will also support new minor platform updates automatically, without requiring any update of PostSharp itself.

Xamarin Support

This is definitively our biggest headline. PostSharp 4.1 now supports Xamarin at the same level of feature as Windows Phone or Windows Store. Excepted the diagnostics pattern library, all PostSharp features are now strictly cross-platform and have been tested on several physical devices.

PostSharp 4.1 is an excellent choice to build large and complex applications for mobile devices and will deliver the same economies of scale as for desktop or server applications, possible saving thousands of lines of codes and hundreds of defects.

Note that Xamarin Studio is not supported. You must build your application on Windows using Visual Studio in order to use PostSharp with Xamarin.

There’s no specific tutorial on how to use PostSharp with Xamarin. It just works as usually: open your project in Visual Studio, move your caret on a class and add an aspect from the smart tag (in VS 2013) or light bulb (in 2015).

Visual Studio 2015 Support

PostSharp Tools have been fully rewritten to take advantage of the new architecture of Visual Studio 2015.

Improvements include:

  • Light bulbs are used instead of the smart tags: not only it looks better, but it also better integrates with other vendors such as Microsoft, Resharper or CodeRush.
  • Real-time code analysis detects the most common errors in seconds so you don’t even have to recompile.
  • Real-time coding guidance shows you what’s the next step to implement more complex patterns like threading models or undo/redo.
  • More accurate parsing of C# code, resulting in higher reliability of PostSharp editor integration.

PostSharp Tools Improvements

Besides VS 2015 support, PostSharp 4.1 includes other significant improvements in the tooling for Visual Studio:

  • Universal apps, the marketing name for shared projects, are now properly supported.
  • PostSharp Explorer is now much more usable and accurate than before.
  • Conservative NuGet Versioning prevents unwanted updates of your NuGet packages. PostSharp will always try to match the version that you’re already using in your solution and will politely ask if an update is needed.

Other Improvements

  • Windows Phone Get Threading. Additionally to Xamarin, PostSharp Threading Pattern Library now becomes available for Windows and Windows Phone (both Silverlight and WinRT), so you can build apps that are both thread-safe and cross-platform.
  • Code Contracts Localization. You can now customize the text of exception messages. Please see the documentation for details.
  • No Strong-Name Verification at build-time. It does not affect strong names at run-time.
  • Automatic support of minor platform updates. Minor updates (like from 4.5 to 4.5.1) should now be automatically supported without any PostSharp update.

Summary

PostSharp 4.1 is all about new platforms. With complete support for Windows Phone, Android and iOS, you can leverage the boilerplate-cutting power of PostSharp to your mobile applications. And we proved we’re ready for Visual Studio 2015, with exciting new features that will improve your productivity.

Happy PostSharping!

It’s hot from the oven! Just this quick post to announce that PostSharp 4.1 RC is out. You can download it from NuGet (make sure to enable pre-releases) or from our web site.

I’ll not completely repeat the previous announcements, but here is a short list of the main features:

    • Xamarin Support, now at the same level of functionality and testing as Windows Phone. It lets you use PostSharp to build applications that target iOS and Android, additionally to Windows, Windows Phone, and Windows 8.
    • Visual Studio 2015 Support, including light bulb integration, live code diagnostics and coding guidance, makes it easier to get started with PostSharp, and then assists you in more complex tasks.
    • Conservative NuGet Versioning prevents unwanted upgrades of PostSharp packages.
    • PostSharp Explorer Improvements let you see where aspects are being used in your code.
    • Shared Projects Support makes PostSharp integration with Visual Studio more relevant in large cross-platform projects.
    • Localizable Code Contracts allow you to customize or localize the runtime exception texts thrown by code contracts.

For more details, please see the previous release announcements.

As usually, RC quality means that we consider the quality of this release to be the same as of an RTM release, with the exception of end-user testing. It also means that the documentation is available.

We won’t have time to blog much more for this RC release, this is why we are hiring a Developer Evangelist to help us do a better job with our communication.

Happy PostSharping!
