As the title says i'm looking for something like SqlTableDependency but for MySql that is usable for free. I've been searching for some time if there are none are there any alternatives ? I need it to be able to notify if data changed in the database on a specific query

Link to the SqlTableDependency

What I have tried:

I have tried Devart.data.MySql but apparently you need a license for that .

As far as i know, there's no free alternative. And seems that Devart environment is the only one.

One option is to make MySQL write an empty (auto incremented filename) file each time an update is performed into a folder. Best way to do this is either to use Triggers or to encapsulate your functionality into Stored Procedures and call the update function after each completes. You will ofc need permissions in MySQL to write to files.

Then you can use FileSystemWatcher in C#, point it to the folder and each time an update on the database takes place an event will be fired.

Not perfect, but it works. Look elsewhere if you need fast real-time updates, but on a local LAN with 10-20 users this should be fine.
