Claude Desktop
You:What was the last error on staging?
Claude:Let me check the staging error logs...
> Calling set_default_environment("staging")
> Calling get_last_error()
Claude:Found a NullReferenceException in NewsController.cs:42 from 2 hours ago.
The
GetRelatedItems() call is failing because the taxonomy field "Category" returns null when no categories are assigned. You need a null check before the .Select() call. Diagnostics & Logs

Sitefinity Widgets
Production-ready components for your Sitefinity projects
Tabstrip
Drag-Drop widgets into a native Bootstrap or Kendo tabstrip. The only tabstrip component available for Sitefinity that allows hosting of any content
Html Content Block
Enter your content in a full-screen instance of VSCode in the browser, nothing to install, with intellisense and syntax highlighting. No content parsing, this thing is fast.
Markdown Editor
Enter content as markdown, get a live preview to the right as you enter it. Nothing is cleaner than markdown, definitely not wysiwyg editors which bloat markup.
Page Title
Drop on the top of a page to pull in the title automatically, or edit to change. Template is global so you can easily restyle site-wide without editing 1000 content blocks.
Google Maps
Drag-Drop google map widget, with just about every option configurable in the designer
Widget Finder
Ever wanted to know which pages contain which widgets (even layouts)... then this is your jam.
