.NET Recap

Let's remember .NET fundamentals

.NET Framework

• Development platform for building apps for web, Windows, Windows Server, and Microsoft Azure
• Components
  • Common language runtime (CLR)
  • .NET Framework class library
• .NET Framework services include:
  • Memory management
  • Type and memory safety
  • Security
  • Networking
  • Application deployment
• Data structures and APIs that abstract the lower-level Windows operating system
• Supports many programming languages including C#, F#, and Visual Basic

.NET Core

• Cross-platform and open source implementation of .NET
• Future of .NET
• Important components
  • Core Common Language Runtime (CoreCLR)
  • Core Base Class Library (CoreFX)
  • .NET Core SDK
• .NET Standard
  • A formal specification of .NET APIs that are available in each .NET implementation

We will focus on .NET Core and .NET Standard in the C# course

Xamarin

• Use C# to write mobile apps for Android and iOS
• Cross-platform mobile development (Xamarin.Android and Xamarin.iOS)
  • Code reuse
  • Reduces effort for building an app for multiple platforms
  • Bindings and interop to underlying SDKs and native languages (e.g. Java, Objective-C)
• Compiled to native code, not interpreted
  • Good performance

We will focus on Xamarin and Xamarin Forms in the Mobile Computing course
