    Study Notes

    .NET Framework Overview

    • .NET Framework is a Microsoft software platform for developing Windows and web applications.
    • It includes development tools, programming languages, and libraries for building desktop and web applications.
    • It's also used for websites, web services, and games.
    • A narrow view of .NET Application shows a hierarchical structure, from .NET Application, to .NET Framework, then to Operating System and hardware.

    .NET Framework Architecture

    • The .NET Framework consists of the Common Language Runtime (CLR).
    • The CLR is the core of the .NET Framework, acting as a runtime environment for managing and executing applications.
    • Managed code runs under the CLR, enabling programmers to avoid memory management.

    Managed Code

    • Code running within the CLR's management is called managed code.
    • Managed code benefits from automatic memory management and thread management by the CLR.

    JIT Compiler

    • The JIT compiler translates MSIL code into native machine code for efficient execution.
    • It translates instructions only when needed (Just-In-Time)

    Intermediate Language (MSIL/CIL)

    • MSIL (Microsoft Intermediate Language) is a language-agnostic format.
    • The .NET compiler converts a programming language's code to MSIL.
    • JIT compilers translates the MSIL into the native code specific to a given computer platform.

    Base Class Libraries (BCL)

    • The BCL (Base Class Library) is a collection of reusable types, classes, and methods that simplify development.
    • It includes functionalities like file reading/writing, graphics, database interaction, and XML manipulation.

    ADO.NET and XML

    • ADO.NET provides access to relational databases.
    • It includes ways to deal with XML data, including disconnected data models.

    Web Forms and Web Services

    • Web Forms is a component for creating user interfaces.
    • Web Services are applications that interact over a network.
    • They employ protocols like UDDI, WSDL, SOAP, XML, HTTP, and SMTP for communication.

    Common Language Specification (CLS)

    • The CLS defines a set of rules for languages wanting to interact compatibly with the .NET framework.
    • CLS facilitates unification and interoperability across languages.

    Assemblies

    • Assemblies are the fundamental building blocks of managed code.
    • Containing .NET application's code, resources, and metadata.
    • Assemblies are composed of manifest files and MSIL.

    Common Language Runtime (CLR)

    • The CLR is the core of the .NET Framework; providing runtime and type management.
    • The core of the .NET framework; responsible for compiling and executing managed code.
    • It handles memory management and thread management.

    Data Types (CTS)

    • The common type system (CTS) helps to define types throughout various programming languages.
    • CTS facilitates common data structures and variable types.
