How to create rich text editor in WPF RichTextBox (SfRichTextBoxAdv)?

WPF RichTextBox (SfRichTextBoxAdv) control, a.k.a. WYSIWYG rich text editor, allows you to view, edit, format, and print rich text content including text, images, hyperlink and more. It helps you create a rich text editor in C#. It also provides all the common Word processing features and helps you add a comprehensive word processor to your WPF applications using a familiar Microsoft Word-like ribbon interface for your end users.

Steps to create rich text editor in C#:

1. Create a new WPF application project.

2. Install the Syncfusion.SfRichTextBoxAdv.WPF NuGet package as a reference to your WPF application from NuGet.org.
