1. .NET Core

2. .NET Standard

3. ASP.NET Core

Was ist .NET Core?

„.NET Core is the modular and high performance implementation of .NET for creating web applications and services that run on Windows, Linux and Mac. It is open source and it can share the same code with .NET Framework and Xamarin apps.“

“.NET Core is a blazing fast, lightweight and modular platform for creating web applications and services that run on Windows, Linux and Mac.”

Was ist der .NET Standard?

.NET API Spezifikation

Vereinheitlicht die APIs aller .NET Plattformen .NET Framework, .NET Core, Xamarin, (UWP)

Aktuell 2.0

Je größer die Versionsnummer, desto größer die API

Stellt Interop und kompatibilität zwischen den Plattformen her.

„.NET Standard solves the code sharing problem for .NET developers by bringing all the APIs that you expect and love across the environments that you need: desktop applications, mobile apps & games, and cloud services.“

.NET bisher — App Models und Libraries

.NET bisher — Code wiederverwenden

.NET ab heute

.NET ab heute — Code wiederverwenden

Unterschied zu Portable Class Libraries (PCL)

PCLs were an after thought, i.e. each platform could

decide which APIs to includes No systematic approach to versioning

Computed intersection profiles

Each PCLs is targeting a specific set of platforms Not compatible with newer platforms

Hard to understand compatibility relationships

Platform 3Platform 1

Platform 2

Versionierung im .NET Standard?

Higher versions incorporate all APIs from previous versions. Projects targeting version X.Y can reference

libraries & projects targeting any version between 1.0 and X.Y

Concrete .NET platforms implement a specific version of .NET Standard From that platform you can reference

libraries up to that version

Neue APIs in .NET Standard 2.0

Sockets • Http • Mail • WebSocketsNETWORKING

BinaryFormatter • Data Contract • XMLSERIALIZATION

XLinq • XML Document • XPath • Schema • XSLXML

Abstractions • Provider Model • DataSetDATA

Wie arbeitet der .NET Standard?

.NET Standard is represented by The NuGet package NetStandard.Library which contains the reference

assembly netstandard.dll

At build time .NET Standard bridges references to existing .NET Framework and PCL

assemblies via type forwarding

At runtime Each platform provides an implementation for netstandard.dll that type

forwards to its implementation

Platformspezifische APIs & .NET Standard

.NET Standard (mostly) only contains APIs that will work everywhere MSFT generally avoid adding large chunks of APIs that don’t work everywhere

A small set of APIs will throw PlatformNotSupportedException

Platform specific APIs sit on top of .NET Standard & you can add references to them Examples: Registry, Reflection Emit, Access Control, Windows Identity

You’ll become less portable

.NET Core und .NET Standard

.NET Core is an implementation of the .NET Standard

They are fully separated, e.g. different GitHub repositories

.NET Standard updates are coordinated across all .NET implementers There is a .NET Standard review board

.NET Core can be updated independently Used by us to experiment and accelerate innovation
