C# and the .NET Framework: Introduction and Basics

C# Basics

• C# is pronounced as "C sharp"
• C# is approved as a standard by the ECMA (European Computer Manufacturers Association) organization

CLI and Applications

• CLI (Common Language Infrastructure) is a platform that allows C# code to run on multiple platforms
• C# can be used to develop various types of applications, including:
  • Windows applications
  • Web applications
  • Mobile applications
  • Games

Design Influences

• C# design is influenced by languages such as C++, Java, and Delphi
• C# is designed to be a modern, object-oriented language that is easy to use and maintain

Features and Benefits

• C# features include type safety, which ensures that the code is free from type-related errors
• The benefit of C# being type safe is that it prevents errors and improves code quality
• C# features interoperability, which allows programs to interact with other languages and systems
• Interoperability in C# allows programs to use existing code and libraries written in other languages
• C# is described as scalable and updateable, making it easy to maintain and evolve large systems

Component-Oriented Language

• C# is a component-oriented language, which means it allows developers to break down programs into smaller, reusable parts
• The main advantage of using C# as a component-oriented language is that it promotes code reuse and reduces development time

Functions and Compilation

• Dividing programs into parts using functions in C# allows for better organization and reuse of code
• The advantage of the fast speed of compilation and execution in C# is that it allows developers to quickly test and iterate on their code

.NET Framework

• The .NET Framework is primarily used for developing Windows applications and web services
• The .NET Framework provides a range of functionalities and support, including:
  • Memory management
  • Security
  • Networking
  • Database access
• The .NET Framework provides a common runtime environment for C# code to run on

CLR and MSIL

• The Common Language Runtime (CLR) is a key component of the .NET Framework that provides a runtime environment for C# code
• The purpose of CLR is to manage the execution of C# code and provide services such as memory management and security
• The .NET CLR's intermediate language (MSIL) is a platform-agnostic language that allows C# code to run on multiple platforms
• MSIL is compiled to native code at runtime, allowing for efficient execution of C# code
