Study Notes
Introduction to C# and .NET 6
- C# and .NET were introduced in 2002 and are major components of software development
- .NET enables multiple programming languages (C#, VB.NET, F#) to interact seamlessly
- .NET Core, launched in 2016, allows cross-platform development (Windows, iOS, Linux/macOS)
- .NET 5 removed the "Core" designation
- C# 10 and .NET 6 were released in November 2021
- C# 10 features are tied to .NET 6 and later
- .NET development frameworks include ADO.NET, Entity Framework Core, Windows Presentation Foundation (WPF), and ASP.NET Core.
.NET Support Lifecycle
- Microsoft now uses a Long-Term Support (LTS) model for .NET
- LTS versions receive extended support and critical fixes for several years
- Support also includes Current Releases between major LTS releases
Preview of .NET Building Blocks
- .NET Runtime, CTS (Common Type System), and CLS (Common Language Specification) are fundamental to .NET
- The .NET Runtime is a runtime environment with base types and specifications tied to specific platforms.
- CTS specifications describe supported data types, programming constructs and their interactions
- CLS is a subset of CTS defining common programming features that .NET languages should support
- Base class libraries (.NET BCLs) are language-agnostic and platform-independent
- Key use of .NET libraries are providing base types and services for all .NET applications
The role of .NET Standard
- .NET Standard is a specification that defines a common set of .NET APIs
- This specification is crucial in maintaining compatibility across .NET implementations
- .NET Standard 2.1 enables interoperability with .NET Framework (with limitations)
C# Characteristics
- C# syntax has similarities to Java and other C-family languages
- It supports modern programming constructs (lambda expressions and LINQ)
Role of Base Class Libraries
- .NET BCLs provide essential types for various applications
- BCLs cover many services (threading, I/O, and graphical systems), plus interactions with external hardware
Role of .NET Standard
- .NET Standard is crucial for ensuring that .NET Framework and .NET Core code can function together smoothly
Understanding the Common Type System (CTS)
- Supported types include classes, interfaces, structures, enumerations, and delegates
- This allows different parts of programs in languages like c#, VB.NET to interact with one another
The Role of the Assembly Manifest
- Assembly Manfiest describes the assembly itself, version number, external dependencies.
Understanding the Common Language Specification (CLS)
- The CLS defines core features that .NET programs can use for compatibility amongst .NET languages
- This is crucial for components in one language being able to work with components written in another language
- CLS rules focus on the public portions of .NET types
Understanding .NET Runtime
- The .NET Runtime is a set of services that manages the execution of code
Distinguishing Assembly, Namespace, and Type
- Assemblies group semantically related types
- Namespaces logically organize types in an assembly (ex: System.IO)
- Types are the individual components of the system (ex: System.Console)
Accessing a Namespace Programmatically
- Using the
usingkeyword in C# simplifies namespace references.
File-Scoped Namespaces (New 10.0)
- File-scoped namespaces enable placing types directly within a file without curly braces or namespaces
