- The .NET Framework
NET Framework includes a set of standard class libraries.
A class library is a collection of methods and functions that can be used for the core purpose. For example, there is a class library with methods to handle all file-level operations. So there is a method which can be used to read the text from a file. Similarly, there is a method to write text to a file. Most of the methods are split into either the System. We will learn these namespaces more in detail in the subsequent chapters.
Languages The types of applications that can be built in the. Net framework is classified broadly into the following categories. WinForms — This is used for developing Forms-based applications, which would run on an end user machine. Notepad is an example of a client-based application.

Net — This is used for developing web-based applications, which are made to run on any browser such as Internet Explorer, Chrome or Firefox. The Web application would be processed on a server, which would have Internet Information Services Installed. The result of the execution is then sent to the client machines, and the output is shown in the browser.
Microsoft always ensures that. Net frameworks are in compliance with all the supported Windows operating systems. Net Framework Design Principle The following design principles of the. Net framework is what makes it very relevant to create. Net based applications.

Interoperability - The. Net framework provides a lot of backward support. Suppose if you had an application built on an older version of the. Net framework, say 2. And if you tried to run the same application on a machine which had the higher version of the. Net framework, say 3. The application would still work. This is because with every release, Microsoft ensures that older framework versions gel well with the latest version. Portability- Applications built on the.
Net framework can be made to work on any Windows platform.

And now in recent times, Microsoft is also envisioning to make Microsoft products work on other platforms, such as iOS and Linux. Security - The. NET Framework has a good security mechanism. The inbuilt security mechanism helps in both validation and verification of applications. Every application can explicitly define their security mechanism. Each security mechanism is used to grant the user access to the code or to the running program.
Memory management - The Common Language runtime does all the work or memory management. Net framework has all the capability to see those resources, which are not used by a running program. It would then release those resources accordingly. This is done via a program called the "Garbage Collector" which runs as part of the. The garbage collector runs at regular intervals and keeps on checking which system resources are not utilized, and frees them accordingly. Simplified deployment - The.
Net framework also have tools, which can be used to package applications built on the. These packages can then be distributed to client machines. The packages would then automatically install the application. Net is a programming language developed by Microsoft.
It was designed to build applications which could run on the Windows platform. Net programming language can be used to develop Forms based applications, Web based applications, and Web services. Developers can choose from a variety of programming languages available on the.
Net platform. The most common ones are VB. Inheritance is What is an Interface Class? Interfaces are used along with classes to define what is known as a What is Queue in C? The Queue is a special case collection which represents a first in first out NET Framework, an integral component of Windows that includes a virtual execution system called the common language runtime CLR and a unified set of class libraries. The CLR is the commercial implementation by Microsoft of the common language infrastructure CLI , an international standard that is the basis for creating execution and development environments in which languages and libraries work together seamlessly.
The IL code and resources, such as bitmaps and strings, are stored on disk in an executable file called an assembly, typically with an extension of.
An assembly contains a manifest that provides information about the assembly's types, version, culture, and security requirements. When the C program is executed, the assembly is loaded into the CLR, which might take various actions based on the information in the manifest.
C# vs .Net
The CLR also provides other services related to automatic garbage collection, exception handling, and resource management. Code that is executed by the CLR is sometimes referred to as "managed code," in contrast to "unmanaged code" which is compiled into native machine language that targets a specific system. The following diagram illustrates the compile-time and run-time relationships of C source code files, the. Language interoperability is a key feature of the. A single assembly may contain multiple modules written in different. NET languages, and the types can reference each other just as if they were written in the same language.
The .NET Framework
In addition to the run time services, the. NET Framework also includes an extensive library of over classes organized into namespaces that provide a wide variety of useful functionality for everything from file input and output to string manipulation to XML parsing, to Windows Forms controls.
The typical C application uses the. NET Framework class library extensively to handle common "plumbing" chores.
