List of must-know .NET libraries, organized by their primary usage:

General Purpose Libraries

·?????? Framework Class Library (FCL): A comprehensive collection of reusable classes, interfaces, and value types that provide system functionality for .NET applications.

·?????? Base Class Library (BCL): A subset of FCL that includes core functionalities essential for .NET applications, such as collections, file I/O, and data access.

Web Development

·?????? ASP.NET: A framework for building web applications and services. It supports MVC architecture and Web API development.

·?????? SignalR: A library for adding real-time web functionality to applications, allowing server-side code to push content to connected clients instantly.

·?????? SaaSKit: Facilitates the development of multi-tenant SaaS applications with resource optimization.

Data Access

·?????? Entity Framework (EF): An Object-Relational Mapper (ORM) that simplifies database interactions by allowing developers to work with data as domain-specific objects.

·?????? Dapper: A lightweight ORM for .NET that provides a simple way to map database results to Cobjects with minimal overhead.

Serialization and XML Handling

·?????? Newtonsoft.Json (Json.NET): A popular library for parsing JSON data and converting between .NET objects and JSON.

·?????? System.Xml: Provides classes for working with XML documents, including reading, writing, and querying XML data.

Testing

·?????? xUnit: A free, open-source testing tool for .NET that supports test-driven development (TDD).

·?????? Moq: A mocking library for .NET that helps create mock objects for unit testing.

Logging

·?????? NLog: A flexible logging framework for various .NET platforms, allowing developers to log messages to different targets like files, databases, or console.

·?????? Serilog: Another logging library that provides structured logging capabilities to enrich log data with additional context.

Security

·?????? IdentityServer: A framework for implementing authentication and authorization in .NET applications using OpenID Connect and OAuth 2.0.

·?????? Microsoft.AspNetCore.Authentication: Provides authentication middleware for ASP.NET Core applications.

UI Development

·?????? Windows Presentation Foundation (WPF): A UI framework for building desktop applications on Windows with rich user interfaces.

·?????? Blazor: A framework for building interactive web UIs using C instead of JavaScript.

Networking

·?????? System.Net.Http: Provides a programming interface for sending HTTP requests and receiving HTTP responses from a resource identified by a URI.

·?????? RestSharp: A simple REST client for .NET that makes it easy to consume RESTful APIs.

Utility Libraries

·?????? AutoMapper: A library that automates the mapping of one object type to another, reducing the need for manual mapping code.

·?????? FluentValidation: A library for building strongly typed validation rules in a fluent interface style.
