Introduction

It can be difficult to create PDF files programmatically in .NET. The PDF document file format was created with printers in mind rather than developers in mind. And there aren't many built-in libraries or functionality for PDF production in C#.

The logic to "create PDF document" or "HTML to PDF conversion" may be simple with C# and IronPDF. Much of the PDF document design and layout may be assigned to web design personnel or done using existing HTML assets.

C# PDF Library IronPDF

IronPDF is the ideal solution for converting HTML sites in .NET and .NET core projects. It not only transforms HTML but also has a lot of other useful capabilities. IronPDF allows developers to create, alter, and retrieve PDF documents from within .NET Core and framework projects. The IronPDF package allows developers to rapidly produce or alter PDFs from HTML texts.

IronPDF allows you to read data from PDF files and inject it into your .NET applications and data storage systems automatically. You may import, move, and index content from legacy PDF document storage into your document management and business process applications.

Creating a New Project in Visual Studio

Open the Visual Studio software and go to the File menu. Select "new project" and then select console application. In this article, we are going to use a console application to generate PDF documents.

Enter the project name and select the path in the appropriate text box. Then, click the create button. Select the required .NET framework, as in the screenshot below:

The Visual Studio project will now generate the structure for the selected application, and if you have selected the console, Windows, and web application, it will open the program.cs file where you can enter the code and build/run the application.
