title: MathML equation editor widget for ASP.NET site
body: <p>I am looking for a widget that I can plug in to my ASP.NET site that will allow users to create math formulas with their associated MathML. Ideally this would be similar to an HTML editor like TinyMCE.</p>
  
  <p>There have been solutions in the past (see <a href="https://stackoverflow.com/questions/698272/mathml-latex-or-similar-for-web-based-wysiwyg-editor">MathML, Latex or similar for web-based WYSIWYG editor</a>), but everything I find seems to have been discontinued.</p>
  
  <p>Free and open source is preferred but we do have a budget or 3rd party tools.</p>
