IT1808 .NET Framework C# Introduction Quiz

C# Features and Development

• C# supports development of both console and web applications through its versatile framework.
• Anders Hejlsberg led the development of C# at Microsoft in the late 1990s.
• Variables in C# are automatically initialized to zero when declared.

.NET Framework Components

• The .NET Framework offers an environment that simplifies the building and deploying of various applications.
• Lambda expressions enhance programming in C# by allowing concise inline function definitions.
• C#'s advanced features increase the language's scope, power, and usability.

Common Language Runtime (CLR)

• The CLR is crucial in the .NET framework, providing services such as memory management, security, and exception handling.
• The .NET framework's debugging and exception handling is facilitated by components integrated within its architecture.
• Microsoft Intermediate Language (MSIL) serves as the low-level language to which C# code is compiled before execution.

Just-In-Time (JIT) Compiler

• The JIT compiler in the .NET framework translates MSIL into native machine code at runtime, optimizing performance.

Application Development Components

• The .NET framework contains extensive classes and interfaces essential for application development.
• ADO.NET handles data access in the .NET framework, allowing developers to interact with databases efficiently.

Assembly Information

• Each assembly's Manifest stores metadata, such as versioning and dependencies.
• Assembly version numbers are represented in a four-part format: Major, Minor, Build, and Revision.
• The distinction between private and shared assemblies lies in their accessibility and deployment; private assemblies are unique to an application while shared assemblies can be used by multiple applications.

Global Assembly Cache (GAC)

• Registering a shared assembly in the GAC is necessary to prevent version conflicts among applications using that assembly.

Strong Names and Assembly Behavior

• Strong names are required for an assembly to ensure uniqueness and version control in the GAC.
• An application using a private assembly will cease to function if that assembly is moved or deleted.

Input and Output in C#

• The 'Console.ReadLine()' method in C# is responsible for capturing user input as a string.
• The 'using' keyword simplifies namespaces management and resource management by ensuring proper disposal of objects.
• The statement 'Console.ReadKey()' is used to pause program execution until a key is pressed, typically for output observation.

Program Structure in C#

• The namespace declaration organizes code and avoids naming conflicts within a C# program.
• Program logic and statements are typically found in the Main method, which must be defined within a class.
• The 'Convert.ToInt32()' method converts various data types to an integer, commonly used for user input validation.

Code Management in C#

• Comments in a C# program are used for documentation and clarification, aiding both the creator and future developers.
• The Main method should be the entry point of execution and is usually defined in the program's main class.
• Errors occur if statements or expressions are not correctly terminated with a semicolon, leading to compile-time errors.

File and Argument Management

• A C# file should match its class name for consistency, adhering to naming conventions.
• The Main method often takes a string array as an argument, allowing command-line input when the application runs.
