Common Language Runtime

The Common language run-time simplifies application development provides a robust and secure execution environment, support multiple language and simplifies application deployment and management.

Common Language Runtime Components

.Net Framework class Library Support
Thread Support		COM Marshaler
Type Checker		Exception Manager
Security Engine		Debug Engine
MSIL to Native Complier	Code manager	Garbage Collector
Class Loader

Component	Description
Class Loader	Manages metadata , in addition to the loading and layout of classe.
MSIL to Native Compiler	Convert MSIL to Native code (Just-in-time JIT Compilation)
Code Manager	Manages code execution.
Garbage Collector	Provides automatic lifetime management of all your object. This is a multiprocessor, scalable garbage collector.
Security engine	Provides evidence-based security that is based on the origin of the code and the user.
Debug engine	Allow you to debug your application and trace the execution of the code.
Type Checker	Will not allow unsafe casts or uninitialized variables. MSIL can be verified to guarantee type safety.
Exception Manager	Provides structured exception handling, which is integrated with Microsoft Windows structured exception handling.
Thread Support	Provides classes and interfaces that enable multi threaded programming.
COM Marshaler	Provides marshaling to and from COM
.Net Framework Class Library Support	Integrates code with the runtime that supports the .NET framework class library.

Microsoft .NET Framework

.Net Framework

• It is environment for developing, building, deploying and executing desktop applications, web applications and web services.
• Major components of .NET Framework
  • The common language run time (CLR), which is the execution engine that handles running apps.
  • The .NET Framework Class Library, which provides a library of tested, reusable code that developers can call from their own apps.
  • Class libraries provides reusable code for most common tasks, including data access, XML Web service development and web and Windows form

Common Language Run-time CLR

The Common language run-time simplifies application development provides a robust and secure execution environment, support multiple language and simplifies application deployment and management.

• The .NET Framework provides a run-time environment called the common language runtime.
• The runtime handles runtimeservices, including language integration, security and memory management.

Common Type System

• Support cross-language integration

• Establishes a framework that helps enable cross-language integration, type safety, and high-performance code execution.

• Provides an object-oriented model that supports the complete implementation of many programming languages.

• Defines rules that languages must follow, which helps ensure that objects written in different languages can interact with each other.

• Provides a library that contains the primitive data types (such as Boolean, Byte, Char, Int32, and UInt64) used in application development.

What Problem does .NET solve?

• Even with the internet , most applications and devices have trouble communicating with each other.
• Developers spend the majority of their time rewriting applications to work on each type of platform and client, rather than spending their time designing new applications.
