RazorRichText is presented as a NuGet package that wraps Quill for Razor-based ASP.NET Core forms, aiming to reduce the work of embedding the editor, binding its value, sanitizing submitted HTML, and validating an empty editor. Those capabilities are reported in Steven Kamwaza’s article, not independently verified against the package’s current code or NuGet listing. If you are considering it, check its current .NET target, setup API, and sanitization behavior before adopting it.

What RazorRichText is reported to do

In his article, Steven Kamwaza describes RazorRichText as a Quill wrapper for ASP.NET Core Razor applications. The article’s indexed excerpt says it provides an asp-for binding for a string, a Razor tag helper, sanitization of submitted HTML, and special handling for Quill’s visually empty value, <p><br></p>.

The excerpt also reports that the package targets ASP.NET Core on .NET 10, includes Quill and its CSS and JavaScript assets, and uses a one-time setup in Program.cs to register services and map those assets. It does not establish the current package release, exact API names, complete setup code, or compatibility with other target frameworks. Confirm those details in the current NuGet listing and repository before following an implementation guide. Kamwaza calls the package MIT-licensed; that license statement has not been independently verified.

Kamwaza’s summary is: “RazorRichText is a MIT-licensed NuGet package that does those jobs for you.” Treat that as the author’s description of the package, not a substitute for inspecting its implementation.

What Quill contributes—and what remains configurable

Quill describes itself as a free, open-source, API-driven rich-text editor. Its product page says applications can access content, changes, and events through an API, with JSON as the input and output format; it also lists support for modern desktop, tablet, and phone browsers. See Quill’s official product page.

A wrapper does not remove the need to decide how the editor should behave in your form. Quill’s configuration documentation covers the container, toolbar modules, placeholder, read-only mode, allowed formats, and theme. Its built-in themes are Snow and Bubble, and a theme stylesheet must also be included. Review Quill’s configuration documentation when deciding which features and formats your application needs. Quill identifies its license as BSD and says it is maintained by Slab.

Sanitization is not the whole XSS defense

Kamwaza’s article says RazorRichText sanitizes submitted HTML, but that claim alone does not establish which elements or attributes its sanitizer permits, how it handles unsafe URLs, or whether its policy matches your application. Those details matter because rich text is HTML that may later be rendered in a browser.

Microsoft’s ASP.NET Core cross-site scripting guidance warns against relying on validation alone and advises encoding untrusted input when it is output. It also notes that Markdown with embedded HTML stripped can be safer when accepting rich input. Treat editor restrictions and server-side sanitization as layers that can reduce risk, not as permission to render arbitrary stored HTML without considering the output context.

  • Decide which formatting and content your application actually needs; do not accept every format merely because the editor can produce it.
  • Check the package’s sanitizer policy and how it handles content submitted outside the editor.
  • Follow ASP.NET Core’s guidance for encoding or otherwise safely handling stored content wherever it is rendered.

How to assess the package before adopting it

RazorRichText may suit a form that needs a Quill field bound to a Razor model, especially if its current integration matches your application’s target framework. Make the adoption decision against your actual requirements:

  • Framework fit: verify the current package target frameworks against your application. The indexed article reports .NET 10; it does not establish compatibility with other versions.
  • Setup and assets: inspect the current registration and asset-mapping instructions. Confirm whether embedded assets fit your deployment, caching, and update-control needs.
  • Content and security policy: verify the accepted formats and sanitizer behavior, then trace how saved content is rendered in your application.
  • Editor experience: decide on toolbar controls, placeholder, theme, read-only behavior, and browser support using Quill’s documented configuration options.
  • License and maintenance: confirm the package’s current license and release status in its repository or NuGet metadata rather than relying only on the article’s description.

If what you need is document authoring and export rather than a rich-text field in a web form, that is a different category. For example, the DevExpress ASP.NET Core RichEdit NuGet listing describes document editing and formats including DOC/DOCX, RTF, TXT, HTML, and PDF export; that does not make it equivalent to RazorRichText. See the DevExpress ASP.NET Core RichEdit NuGet listing.
