16. Assembly Manifest Type Metadata Resources CIL Assembly Meta Information Common Intermediate Language Earlier called Microsoft Intermediate Language or MSIL or IL Also referred as Managed Code Is an object-oriented assembly language Advantages Platform Independence Language Independence Information about all types used in source code Optional part Details of external resources if used www.dotnetvideotutorial.com Consist of Meta-information and CIL Basic Building blocks of .NET Framework Self Descriptive Two Types Private Public Information about assembly Assembly name Assembly Version Security Key References to other assemblies used

17. Resources required to develop and execute the applications Typically includes a hardware architecture and a software framework Platform Independence Machine Code JIT Assembly Loader Assembly / PE (exe / dll ) Meta Information CIL Code C# Compiler C# Source Code (Uses ref of dlls from FCL) Development Platform Production Platform .

21. CLR CLS works with the CTS to ensure language interoperability The CLS is a set of minimum standards that all compilers targeting .NET must support. GC CAS CLS JIT CTS FCL Common Type System defines the set predefined data types available in IL Compiles CIL to Machine code compiles portion of code as it is called. And cached Code Access Security Applies the permission to code, based on source of code and other identities garbage collector manages the allocation and release of memory for your application. Reclaims unreferenced or dead objects and clears their memory. Is run-time environment to execute .NET Apps Commercial implementation of CLI by Microsoft Code Execution Exception Handling Resource Management Garbage Collection Code Access Security Just In Time Compilation Language Interoperability Application Isolation Common Language Infrastructure is an international standard that is the basis for creating execution and development environments in which languages and libraries work together seamlessly. www.dotnetvideotutorial.com

22. CLR 2.0 FCL 2005 GC CAS CLS JIT CTS Set of common classes need in various types of applications. Typically classes in System namespace. Set of classes to be used for database communication Provides architecture, library and controls to develop desktop applications. Library of tested, reusable code that developers can use in own applications Consists of classes, interfaces, and structures, delegates etc. Categorized using Namespaces Namespaces support the hierarchical organization of classes and prevent type name collisions Provides architecture to develop web applications and web services . Subsets are WebForms XML WebServices www.dotnetvideotutorial.com

23. CLR FCL presentation system for building Windows client applications with visually stunning user experiences. resolution-independent and vector-based rendering engine Features: XAML, 3D Graphics, Animation, Media, etc GC CAS CLS JIT CTS 2.0 2005 3.0 2006 framework for building service-oriented applications. Workflows provide a way of describing the order of execution and dependent relationships between pieces of short- or long-running work. provides a standards-based solution for working with and managing diverse digital identities. Discontinued from Feb 2011 Microsoft is currently working on a replacement called U-Prove www.dotnetvideotutorial.com

24. CLR FCL GC CAS CLS JIT CTS 2.0 2005 3.0 2006 3.5 2007 Enhancements in Common Language Runtime Enhancements in WPF, WCF, Networking, Windows Forms, etc New server controls and ASP.NET AJAX set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic. www.dotnetvideotutorial.com

25. CLR FCL GC CAS CLS JIT CTS 2.0 2005 3.0 2006 3.5 2007 3.5sp1 2008 object-relational mapper that enables .NET developers to work with relational data using domain-specific objects. It eliminates the need for most of the data-access code that developers usually need to write. ASP.NET Dynamic Data lets you create extensible data-driven Web applications by inferring at run time the appearance and behavior of data entities from the database schema and deriving UI behavior from it. www.dotnetvideotutorial.com

Task Parallel Library set APIs in the System.Threading and System.Threading.Tasks namespaces Efficiently use all the available processors powerful , patterns-based way to build dynamic websites enables a clean separation of concerns gives full control over markup Provides features that enable fast Test Driven Development for creating sophisticated applications that use the latest web standards. The Portable Class Library project enables you to write and build managed assemblies that work on more than one .NET Framework platform. www.dotnetvideotutorial.com
