Version: 7.30.2
Target: .Net Core 3.1

In the C# lib, IpcMain.RemoveAllListeners(string) is not removing the listeners. After executing this function, my event listeners are still firing.

Steps to Reproduce:

Register a listener using IpcMain.On(channel_name)
Wait for the event to be fired at least once from javascript
Now in C# after the event, call `IpcMain.RemoveAllListeners(channel_name)
Fire the event again within javascript
The listener registered at step 1 still fires

I tested it with the current version and there were no problems. Possibly. your code will not be executed with RemoveAllListeners or it is due to the new Electron 8 version. Our latest update in version 8.31.1 will be released in the next few days.

I have the same problem, I have electron and React and when you are using the app for a log time it becomes slow because the number of imports using ipc renderer. I tried to remove al listeners but it continues sending requests.
