Following are the components of .NET
- Common Language run-time
- Application Domain
- Common Type System
- .NET Class Library
- .NET Framework
- Profiling
In a .NET interview, when asked about the different components of .NET, you can provide a comprehensive answer that covers the various key elements of the .NET framework. Here’s a breakdown:
- Common Language Runtime (CLR):
- The CLR is the heart of the .NET framework. It manages memory, code execution, security, and other system services.
- It provides features such as automatic memory management (garbage collection), exception handling, and Just-In-Time (JIT) compilation.
- Framework Class Library (FCL):
- The FCL is a comprehensive library of classes, interfaces, and value types that provides access to system functionality.
- It includes a wide range of APIs for tasks such as file I/O, networking, database access, XML manipulation, and more.
- Languages:
- .NET supports multiple programming languages, including C#, Visual Basic .NET, F#, and others.
- These languages are all compiled into an intermediate language (IL) that runs on the CLR, enabling interoperability among different languages within the same application.
- ASP.NET:
- ASP.NET is a web development framework for building dynamic web applications and services.
- It includes features such as server controls, authentication and authorization mechanisms, session management, and more.
- ADO.NET:
- ADO.NET is a set of classes that facilitate data access and manipulation.
- It provides mechanisms for connecting to databases, executing SQL commands, retrieving and updating data, and handling transactions.
- Windows Presentation Foundation (WPF):
- WPF is a framework for building desktop client applications with rich user interfaces.
- It uses XAML (Extensible Application Markup Language) for defining UI elements and their behaviors.
- Windows Communication Foundation (WCF):
- WCF is a framework for building distributed and interoperable applications.
- It enables services to communicate with each other over various protocols such as HTTP, TCP, MSMQ, etc.
- Windows Workflow Foundation (WF):
- WF is a framework for building workflow-enabled applications.
- It provides tools and APIs for defining, executing, and managing workflows within applications.
- Entity Framework:
- Entity Framework is an ORM (Object-Relational Mapping) framework that simplifies data access by enabling developers to work with relational data as domain-specific objects.
- LINQ (Language Integrated Query):
- LINQ is a set of language features that enable querying data from various data sources directly within C# or VB.NET code.
- It provides a uniform way to query and manipulate data from collections, databases, XML, and other sources.
By discussing these components, you demonstrate a solid understanding of the various aspects of the .NET framework and its capabilities.
