Components of .net Framework

• Common Language Runtime or CLR: Asp.net come with a CLR function that helps it in memory management, debugging, security check, code execution, verification, code safety, compilation and exception handling. The code that is directly managed by the CLR is known as managed code.
• Common Language Specification: Asp.net has those essential specifications that are required for the .Net supported languages and also for the implementation of language integration.
• Common Type System: It caters to those guidelines that are required for declaring, using, and managing types at runtime, and also for cross-language communication.

• Windows Forms: It includes graphical and extensive representation of any window that is displayed in the application.
• Metadata and Assemblies: Metadata is the binary information that describes the program, and is either stored in a portable executable file (PE) or in memory. Assemblies are logical units that comprise of the assembly manifest, type metadata, IL codes, and other resources like image files.
• Windows Communication Foundation (WCF): It is the technology that is used to build and execute connected systems for web applications.
• Windows Presentation Foundation: This presents a distinction the user interface and the business logic. It aids to develop interfaces that are visually stunning and are built using documents, media, two and three dimensional graphics, animations, and more.
• Windows CardSpace: This provides a safe platform for accessing vital resources and sharing personal information on the internet. This helps us to make a safe and secure platform.
• LINQ: It communicates data querying capabilities to other .Net languages that are using a syntax which is similar to the traditional query language SQL.
• ADO.NET: It is the technology that is utilized for working with data and extensive databases. It provides an access to data sources like SQL server, OLE DB, XML etc. for retrieving, manipulating, and updating data.
