The Syncfusion Blazor Spinner Component displays loading states for long-running operations with lightweight circular progress indicators. Ideal for enhancing user experience when task progress information is unavailable.

Using this package with an AI coding agent

Before generating Syncfusion code, ask your AI coding agent to run the Syncfusion setup using the following prompt:

Set up this project for Syncfusion before generating code. Fetch and follow the official instructions at https://ai.syncfusion.com, then report the detected platform, installed skill pack, MCP status, and any required licensing action.

The setup detects your project's platform and loads the appropriate Syncfusion skill pack. No Syncfusion account or MCP key is required to install or read Syncfusion agent skills.
