Setup — three steps
1. Add @addTagHelper *, RichTextBox to _ViewImports.cshtml.
2. In Program.cs, call builder.Services.AddRichTextBox() and app.MapRichTextBoxUploads().
3. Place your RichTextBox.lic file in the app content root (beside Program.cs) so runtime license validation passes for rendering and uploads.
4. Drop <richtextbox name="Body" toolbar="default" /> into any Razor page and you're done — the tag helper renders the editor, wires uploads, and lights up AI / collaboration features per the attributes you set.
All licenses are perpetual and never expire. One-time purchase with no recurring fees.
