Web development with ASP.NET Core and Microsoft SQL Server involves building dynamic and scalable web applications using the ASP.NET Core framework and a MSSQL Server database. Here's a brief overview:

ASP.NET Core:

Framework: ASP.NET Core is a cross-platform, high-performance framework for building modern, cloud-based, and internet-connected applications.

MVC Architecture: ASP.NET Core follows the Model-View-Controller (MVC) architectural pattern, providing a structured way to build and organize code.

Microsoft SQL Server:

Relational Database Management System (RDBMS): Microsoft SQL Server is a robust RDBMS that stores and retrieves data in a structured format.

Integration with ASP.NET Core: ASP.NET Core seamlessly integrates with SQL Server, allowing developers to use Entity Framework Core for efficient data access.

Key Components and Concepts:

Controllers and Actions: Controllers handle incoming requests, interact with the database, and return appropriate responses.

Views: Views define the presentation layer and utilize the Razor syntax for creating dynamic HTML content.

Models and Entity Framework Core: Models represent the data structure and are mapped to the database using Entity Framework Core, simplifying database operations.

Middleware: ASP.NET Core middleware handles various aspects of the request-response pipeline, such as authentication, logging, and error handling.

Entity Framework Core:

Object-Relational Mapping (ORM): Entity Framework Core simplifies database interactions by allowing developers to work with .NET objects, which are then mapped to database tables.

Code-First Development: Developers can use the code-first approach, defining models and relationships in code, and then generating the database schema automatically.

Authentication and Authorization:

ASP.NET Core provides built-in support for user authentication and authorization, making it easy to implement secure user access controls.

Razor Pages:

ASP.NET Core includes Razor Pages, a lightweight alternative to the MVC pattern, suitable for simpler applications.

Dependency Injection:

ASP.NET Core features a built-in dependency injection container, facilitating the organization and management of application components.

Cross-Platform and Open Source:

ASP.NET Core is cross-platform, allowing developers to build and deploy applications on Windows, Linux, and macOS. It is also open source, encouraging community collaboration and contributions.
