title: SQLDependency on a MariaDB/MySQL database
body: <p>I developed a web dashboard that needs to display real-time information (ASP.NET C #). Usually I use SQLServer, so the combination SignalR + SQLDependency works very well. But now I have to use a MariaDB / MySQL database and I can not find a library equivalent to SQLDependency. Is there a "trick" for notifying a change in a database?</p>
  
  <p>I found this library : <a href="https://www.devart.com/dotconnect/mysql/docs/Devart.Data.MySql~Devart.Data.MySql.MySqlDependency.html" rel="nofollow noreferrer">https://www.devart.com/dotconnect/mysql/docs/Devart.Data.MySql~Devart.Data.MySql.MySqlDependency.html</a> but it's not free ... </p>
