Creating a web app is a popular task for many developers. This article will introduce you to how to build a web application using C# and some of the leading tools and frameworks, such as Visual Studio and ASP.NET Core.
As we explore how you can use C# to create any web application that you may need, we will also be exploring how to best use ASP.NET Core throughout the development process, along with the potential of implementing powerful tools such as IronXL, IronOCR, and IronBarcode can help to enhance the web app further.
Visual Studio is a powerful IDE that caters to a variety of web development needs. If you're looking to dive into web apps, this is a great place to start.
Download the Visual Studio Installer: Go to the official Visual Studio website and get the Visual Studio Installer. This is the first step to accessing the multitude of features that Visual Studio offers and getting started on your new project.
ASP.NET Core is a modern web development framework under the .NET Core umbrella. It allows you to build high-performance web applications efficiently.
Versatile: Whether you want to build web apps, web APIs, or even real-time applications, ASP.NET Core has you covered.
Performance: Being a part of .NET Core, it boasts high performance out of the box.
Launch Visual Studio: Once opened, click on 'Create a new project.'
The MVC pattern (Model-View-Controller) is an architectural pattern that divides an app into three interconnected components:
ASP.NET Core beautifully integrates the MVC pattern, streamlining web app creation.
Razor pages are a new feature in ASP.NET Core, providing a more straightforward approach to building web page experiences. They're perfect for developers who want a page-based architecture without the full complexity of MVC.
In Visual Studio, right-click on the 'Pages' folder in your ASP.NET Core project and choose 'Add' followed by 'New Razor Page'. This action creates the necessary web pages for your application.
At the heart of Razor Pages is the Razor syntax – a coding syntax that lets you embed server-based code into web pages. This blend of C# with HTML makes the development process smoother.
For those looking to create backend services for mobile or web clients, ASP.NET Core’s web API feature is invaluable.
To create a Web app, simply follow the steps listed below:
In Visual Studio:
Your new web API is ready for customization and deployment!
Once you've finished building your web application, the final step is deployment. This means getting your web app onto a web server where others can access it.
With ASP.NET Core, you have multiple deployment options:
Middleware components in ASP.NET Core handle requests and responses. They are software units that are assembled into an application pipeline to handle requests and responses.
Understanding Middleware: Imagine a chain where each link represents a step in processing the web app request. Middleware is each of these links.
When building web apps, it's common to interact with databases. Entity Framework Core (EF Core) is an ORM (Object-Relational Mapper) that allows you to work with databases using .NET objects.
Database Operations: With EF Core, operations like creating, reading, updating, and deleting records become straightforward.
Combining web applications with web APIs can amplify your app's functionality.
Consuming APIs: Use built-in libraries in ASP.NET Core to call and utilize web services seamlessly.
When delving deeper into C# web app development, especially within the context of ASP.NET Core and Visual Studio, you might come across specific challenges that require specialized tools. This is where Iron Suite overview steps in.
Iron Suite is a collection of powerful .NET development tools tailored for developers. It aids in enhancing various functionalities of your web applications without the heavy lifting. Each product within Iron Suite is designed to tackle a specific challenge, making them essential for any comprehensive web app toolkit.
IronPDF excels in HTML to PDF conversion, ensuring precise preservation of original layouts and styles. It's perfect for creating PDFs from web-based content such as reports, invoices, and documentation. With support for HTML files, URLs, and raw HTML strings, IronPDF easily produces high-quality PDF documents.
using IronPdf;
class Program
{
static void Main(string[] args)
{
var renderer = new ChromePdfRenderer();
// 1. Convert HTML String to PDF
var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");
// 2. Convert HTML File to PDF
var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");
// 3. Convert URL to PDF
var url = "http://ironpdf.com"; // Specify the URL
var pdfFromUrl = renderer.RenderUrlAsPdf(url);
pdfFromUrl.SaveAs("URLToPDF.pdf");
}
}using IronPdf;
class Program
{

{
var renderer = new ChromePdfRenderer();
// 1. Convert HTML String to PDF
var htmlContent = "<h1>Hello, IronPDF!</h1><p>This is a PDF from an HTML string.</p>";
var pdfFromHtmlString = renderer.RenderHtmlAsPdf(htmlContent);
pdfFromHtmlString.SaveAs("HTMLStringToPDF.pdf");
// 2. Convert HTML File to PDF
var htmlFilePath = "path_to_your_html_file.html"; // Specify the path to your HTML file
var pdfFromHtmlFile = renderer.RenderHtmlFileAsPdf(htmlFilePath);
pdfFromHtmlFile.SaveAs("HTMLFileToPDF.pdf");
// 3. Convert URL to PDF
var url = "http://ironpdf.com"; // Specify the URL
var pdfFromUrl = renderer.RenderUrlAsPdf(url);
pdfFromUrl.SaveAs("URLToPDF.pdf");
}

The best starting point for developing a C# web application is using Visual Studio, a powerful Integrated Development Environment (IDE) that caters to a variety of web development needs.
ASP.NET Core is a versatile, high-performance, and cross-platform framework under the .NET Core umbrella, suitable for building web apps, web APIs, and real-time applications.
The MVC pattern in ASP.NET Core divides an application into three interconnected components: Model (data and business logic), View (user interface), and Controller (handles user input and updates).
Razor Pages provide a more straightforward approach to building web page experiences by integrating server-based code with HTML, making the development process smoother.
ASP.NET Core applications can be deployed on Windows Server, Linux Server, or cloud providers like Azure, which offers seamless integration with Visual Studio.
Middleware in ASP.NET Core are software components that handle requests and responses by assembling into an application pipeline. Developers can also create custom middleware for additional functionality.
Entity Framework Core is an ORM that simplifies database operations like creating, reading, updating, and deleting records using .NET objects, and supports database schema migrations.
Specialized tools like Iron Suite can enhance web applications by providing functionalities such as PDF manipulation, Excel data management, OCR text extraction, and barcode solutions.
Using IronPDF, HTML content, URLs, and HTML files can be converted into PDF documents, preserving original layouts and styles, which is ideal for generating reports, invoices, and documentation in web applications.
