Download as PPTX, PDF0 likes528 views
.NET ecosystem overview covers .NET Standard, Visual Studio 2017, and .NET Core tooling, emphasizing the evolution from Portable Class Libraries (PCLs) to .NET Standard. The document highlights the interoperability and API specifications of .NET Standard, noting it as the preferred choice for new libraries and its significant enhancements in version 2.0. It provides insights on future developments and the integration of .csproj, msbuild, and nuget for better development practices.
Modern .NET Ecosystem
- 1. Modern .NET Ecosystem Andrei Marukovich LunarFrog.com twitter: @amarukovich
- 2. Agenda • .NET Standard • VS 2017 and .NET Core tooling • Usage in practice
- 3. .NET ecosystem .NET Framework .NET Core Xamarin WPF ASP.NET WinForms UWP ASP.NET Core iOS macOS Android
- 4. Code sharing and library types • Source file links • Shared projects • Portable class libraries (PCLs) • .NET Standard
- 5. Shared projects • Better version of the source file links UWP project Xamarin project File1.cs File2.cs SharedLib File1.cs File2.cs SharedLib File1.cs File2.cs SharedLibUI App layer UI App layer
- 6. Portable class libraries • Sharing code in binary form, without recompiling UWP project Xamarin project File1.cs File2.cs PortableLib UI App layer UI App layer
- 7. How it works? • PCLs are based on profiles • Profile defines an API surface supported by the library • Profile is identified by combination of supported platforms • http://embed.plnkr.co/03ck2dCtnJogBKHJ9EjY • C:Program Files (x86)Reference AssembliesMicrosoftFramework.NETPortable
- 10. .NET Standard • An evolution of PCLs, recommended approach for new libraries* • Defines a set of APIs to be implemented by .NET platforms (specification) • Is versioned (API level) • Version defines API surface, not supported frameworks • The higher the version, the more APIs you have • The lower the version, the more .NET platforms implement it • Library developers may choose target .NET Standard version
- 13. Big picture
- 14. .NET Standard • Current state • Tooling is in preview • Currently PCLs support a wider range of platforms • At the moment, PCL adoption (# of libraries) is higher than .NET Standard • Future • PCL replacement • Standard 2.0 will have significantly larger API surface • Standard 2.0 will be interoperable with .NET Framework
- 15. Visual Studio 2017 demo
- 16. Recap • .NET Standard is the future • project.json is obsolete • .csproj, msbuild and NuGet play nicely together
- 17. Additional information • Additions to the csproj format for .NET Core • https://docs.microsoft.com/en-us/dotnet/articles/core/tools/csproj • NuGet pack and restore as MSBuild targets • https://docs.microsoft.com/en-us/nuget/schema/msbuild-targets • How to use new features of MSBuild 15 with .NET Framework projects • http://lunarfrog.com/blog/how-to-use-msbuild15-net-framework
