.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 âą .NET Standard âą VS 2017 and .NET Core tooling âą 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 âą Source file links âą Shared projects âą Portable class libraries (PCLs) âą .NET Standard
- 5. Shared projects âą 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 âą 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? âą PCLs are based on profiles âą Profile defines an API surface supported by the library âą Profile is identified by combination of supported platforms âą http://embed.plnkr.co/03ck2dCtnJogBKHJ9EjY âą C:Program Files (x86)Reference AssembliesMicrosoftFramework.NETPortable
- 10. .NET Standard âą An evolution of PCLs, recommended approach for new libraries* âą Defines a set of APIs to be implemented by .NET platforms (specification) âą Is versioned (API level) âą Version defines API surface, not supported frameworks âą The higher the version, the more APIs you have âą The lower the version, the more .NET platforms implement it âą Library developers may choose target .NET Standard version
- 13. Big picture
- 14. .NET Standard âą Current state âą Tooling is in preview âą Currently PCLs support a wider range of platforms âą At the moment, PCL adoption (# of libraries) is higher than .NET Standard âą Future âą PCL replacement âą Standard 2.0 will have significantly larger API surface âą Standard 2.0 will be interoperable with .NET Framework
- 15. Visual Studio 2017 demo
- 16. Recap âą .NET Standard is the future âą project.json is obsolete âą .csproj, msbuild and NuGet play nicely together
- 17. Additional information âą Additions to the csproj format for .NET Core âą https://docs.microsoft.com/en-us/dotnet/articles/core/tools/csproj âą NuGet pack and restore as MSBuild targets âą https://docs.microsoft.com/en-us/nuget/schema/msbuild-targets âą How to use new features of MSBuild 15 with .NET Framework projects âą http://lunarfrog.com/blog/how-to-use-msbuild15-net-framework
