C# Web Framework (How it Works for Developers)

Published October 29, 2023

With the surge in web development technologies, choosing a reliable and scalable platform is vital. One such platform is the C# web framework, a part of the .NET ecosystem. Whether you're a beginner eager to kick-start your journey in the realm of web applications or an intermediate developer aiming to broaden your knowledge, this tutorial is tailored just for you.

What is a Web Framework?

At its core, a web framework is a software framework designed to support the development of web applications, which includes web services, web resources, and web APIs. Essentially, it provides a standard way to build and deploy web apps on the World Wide Web.

The C#

Before delving into the intricacies of the web framework, understanding the programming language upon which it stands is paramount. C# (pronounced "See Sharp") is a modern, object-oriented language developed by Microsoft. As a part of the .NET family of programming languages, C# offers a rich set of features that enable the creation of robust, scalable, and efficient applications.

.NET Core vs .NET Framework

.NET Framework

The .NET Framework has been a stalwart in the development world since its inception. It offers a comprehensive runtime and class libraries that enable developers to create Windows-based applications with ease. This includes web apps, services, and desktop applications. It tightly integrates with the Windows operating system and is predominantly Windows-centric.

.NET Core

Emerging as a cross-platform successor, .NET Core has rapidly gained popularity. It is a software framework that allows developers to build applications that run seamlessly on macOS, Linux, and Windows. If your aim is cross-platform web development, .NET Core is the go-to choice. It brings with it the advantages of the web application framework along with the capability to create console applications.

Building Web Applications with C#

One of the principal reasons developers flock to C# for web development is the rich set of tools and libraries it offers for building web applications. Let's explore some of these.

ASP.NET Core Web API

An essential part of modern web development, a Web API allows for the creation and consumption of HTTP-based services. ASP.NET Core's Web API feature facilitates this by providing an infrastructure to build RESTful services using C#. With it, handling HTTP requests, routing, and other essential web tasks becomes a breeze.

Entity Framework Version Core

When building a web application, interaction with a database is often inevitable. This is where the Entity Framework comes into play. As a part of the .NET ecosystem, this web application framework simplifies data access with its ORM (Object-Relational Mapping) capabilities. The latest Entity Framework version designed for .NET Core further enhances this experience by being lightweight, extensible, and cross-platform.

Razor Pages

For developers inclined towards a page-focused framework for building dynamic web apps with C#, Razor Pages is the solution. As a feature of ASP.NET Core, Razor Pages simplifies the web app-building process by coalescing the HTML and the C# code written for a page.

Setting Up Your Development Environment

Developing in the .NET ecosystem, particularly with the C# web framework, requires a robust and intuitive environment. This ensures that you have the tools and resources at hand to craft efficient, secure, and scalable web applications. Here's a more comprehensive guide on setting it up

Visual Studio

Microsoft's Visual Studio is not just an Integrated Development Environment (IDE); it's a powerhouse for developers. Its capabilities extend beyond mere code editing.

Here is why we should choose Microsoft Visual Studio:

Integrated Support: Visual Studio caters to both .NET Core and the .NET Framework. This means whether you're building a cross-platform web API or a Windows-centric web application, you have the support you need.

Debugging Tools: One of the standout features of Visual Studio is its advanced debugging capabilities. These tools allow developers to trace issues, inspect variables, and evaluate expressions at runtime.

Database Integration: Visual Studio seamlessly integrates with databases, most notably SQL Server. This integration simplifies tasks like data migration, schema updates, and query testing.

Extensibility: The IDE can be tailored to individual needs with its extensive marketplace of plugins and extensions.
