PostSharp XAML is the new name for PostSharp Model.
New Platforms
Microsoft Visual Studio 2017 – PostSharp now supports the new MSBuild project format, side-by-side installations of VS, lightweight solution loads, and achieved significant performance improvements.
C# 7.0 – Tested and fixed all aspects with the new features of C# 7.0, including value-typed tasks and multiple return values.
Microsoft .NET Core 1.1 – You can now build applications that run on .NET Core 1.1, but you can still only build and debug them on a Windows machine running Visual Studio.
.NET Standard 1.3 – Support for .NET Core is achieved through .NET Standard, so you can use PostSharp in your own .NET Standard class libraries.
New Features
XAML – New aspects added to automate writing boilerplate code for commands and dependency properties.
Code Contracts – It is now possible to add code contracts to return values and out or ref parameters. The values are validated when the method succeeds.
