Improved Documents with Rich Text Controls in C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Create a new document.
  3. Add a rich text content control.
  4. Insert new paragraphs into the control.
  5. Insert a shape and a picture into the control.
  6. Save the document in DOCX format.

A rich text control can contain custom formatted text or other items, such as tables, pictures and shapes, or other content controls.
