Architecture of.net framework.1.Architecture of.NET Framework www.ustudy.in.NET Framework Microsoft.NET (pronounced “dot net”) is a software component that runs on the Windows operating system.NET provides tools and libraries that enable developers to create Windows software much faster and easier. The.NET Framework must be installed on a user’s PC to run.NET applications. Www.ustudy.in.NET Architecture www.ustudy.in.Components of.NET Architecture Microsoft.NET consists of four major components: Common Language Specification (CLS) – blue in the diagram below Framework Class Library (FCL) – red Common Language Runtime (CLR) – green.NET Tools – yellow www.ustudy.in.Architecture – Operating System At the base of the diagram in gray is the operating system, which technically can be any platform but typically is Microsoft Windows 2000 or greater, accessed through the Win32 API (Application Programming Interface). Www.ustudy.in.Common Language Specification (CLS) The CLS is a common platform that integrates code and components from multiple.NET programming languages. In other words, a.NET application can be written in multiple programming languages with no extra work by the developer www.ustudy.in.NET Languages.NET includes new object-oriented programming languages such as C#, Visual Basic.NET, J# (a Java clone) and Managed C. These languages, plus other experimental languages like F#, all compile to the Common Language Specification and can work together in the same application.
Www.ustudy.in.Common Language Specification (CLS) www.ustudy.in.Framework Class Library (FCL) The FCL is a collection of over 7000 classes and data types that enable.NET applications to read and write files, access databases, process XML, display a graphical user interface, draw graphics, use Web services, etc. The FCL wraps much of the massive, complex Win32 API into more simple.NET objects that can be used by C# and other.NET programming languages. Www.ustudy.in.Framework Class Library www.ustudy.in.Common Language Runtime (CLR) The CLR is the execution engine for.NET applications and serves as the interface between.NET applications and the operating system. The CLR provides many services such as: Loads and executes code Converts intermediate language to native machine code Separates processes and memory Manages memory and objects www.ustudy.in.Common Language Runtime (CLR) Cont., Enforces code and access security Handles exceptions Interfaces between managed code, COM objects, and DLLs Provides type-checking Provides code meta data (Reflection) Provides profiling, debugging, etc. Www.ustudy.in.Common Language Runtime (CLR) www.ustudy.in.NET Tools Visual Studio.NET is Microsoft’s flagship tool for developing Windows software. Visual Studio provides an integrated development environment (IDE) for developers to create standalone Windows applications, interactive Web sites, Web applications, and Web services running on any platform that supports.NET.
Www.ustudy.in.NET Tools In addition, there are many.NET Framework tools designed to help developers create, configure, deploy, manage and secure.NET applications and components. Www.ustudy.in.The End Thank You www.ustudy.in. Load iphone backup unlocker serial crack.

ADO.NET ArchitectureADO.NETADO.NET consist of a set of Objects that expose data access services to the.NET environment. It is a data access technology from Microsoft.Net Framework, which provides communication between relational and non relational systems through a common set of components.System.Data namespace is the core of ADO.NET and it contains classes used by all data providers. ADO.NET is designed to be easy to use, and Visual Studio provides several wizards and other features that you can use to generate ADO.NET data access code.Data Providers and DataSetThe two key components of ADO.NET are Data Providers and DataSet. The Data Provider classes are meant to work with different kinds of data sources. They are used to perform all data-management operations on specific databases. DataSet class provides mechanisms for managing data when it is disconnected from the data source.Data ProvidersThe.Net Framework includes mainly three Data Providers for ADO.NET. They are the Microsoft SQL Server Data Provider, OLEDB Data Provider and ODBC Data Provider.

SQL Server uses the SqlConnection object, OLEDB uses the OleDbConnection Object and ODBC uses OdbcConnection Object respectively.A data provider contains Connection, Command, DataAdapter, and DataReader objects. These four objects provides the functionality of Data Providers in the ADO.NET.ConnectionThe Connection Object provides physical connection to the Data Source.
Connection object needs the necessary information to recognize the data source and to log on to it properly, this information is provided through a connection string.CommandThe Command Object uses to perform SQL statement or stored procedure to be executed at the Data Source. The command object provides a number of Execute methods that can be used to perform the SQL queries in a variety of fashions.DataReaderThe DataReader Object is a stream-based, forward-only, read-only retrieval of query results from the Data Source, which do not update the data. DataReader requires a live connection with the databse and provides a very intelligent way of consuming all or part of the result set.DataAdapterDataAdapter Object populate a Dataset Object with results from a Data Source. It is a special class whose purpose is to bridge the gap between the disconnected Dataset objects and the physical data source.DataSetDataSet provides a disconnected representation of result sets from the Data Source, and it is completely independent from the Data Source. DataSet provides much greater flexibility when dealing with related Result Sets.DataSet contains rows, columns,primary keys, constraints, and relations with other DataTable objects. It consists of a collection of DataTable objects that you can relate to each other with DataRelation objects.
The DataAdapter Object provides a bridge between the DataSet and the Data Source.
