Hello, I am a beginner C # developer. I am interested in your qml.net library, please tell me if it’s not difficult for you. Since I cannot use Dispatcher, how can I handle the event safely? Thanks in advance.

For example, I have a library that sends, receives and decodes data, I create an event for decoding and subscribe to it in the main form, if you do not use the dispatcher, the form hangs

I don't really know what you are asking. Can you provide a simple Program.Main with some explanation?

lib.dll
public event EventHandler OnVersion;
public async Task Version()
{
//some actions
OnVersion?.Invoke(this, version);
}
Program.cs
uDP.OnVersion += UDP_OnVersion;
private void UDP_OnVersion(object sender, SomeEventsArgs e)
{
displayResult = $"Firmware version: {e.Version}"
}

On the UDP_OnVersion, you must dispatch the data back to the UI thread with QCoreApplication.Dispatch.
