Unfortunately not.
It's when the whole application (process) is shutting down.

Is there any way to force this `cleanup` and know when it is done cleaning up? Thank you for your help.

Hello,

I am afraid we won't be able to help here.
There is some internal cleanup work that the component does, and we consider this delay as normal.

I am sorry I cannot give you better news...

Best regards

EasyDAClient prevents WinForms application from closing immediately was created by gojanpaolo

Hello,

We use EasyDAClient in a WinForms application. When we use EasyDAClient.SubscribeItem or EasyDAClient.SubscribeMultipleItems, it takes a long time for the application to close immediately (during Visual Studio Debug session).

We tried explicitly calling Dispose, UnsubsribeAllItems, and/or UnsubscribeItem but still doesn't fix the issue.

Here is a sample of our code...

Code:

public partial class frmDemo : Form
    {
        private EasyDAClient _easyDAClient = new EasyDAClient();
        private float MyValue;
        public frmDemo()
        {
            InitializeComponent();
            _easyDAClient.SubscribeItem("", "My.Server.Name", "My.Tag", 50, (s, e) => MyValue = (float)e.Vtq.Value);
        }

        private void frmDemo_Load(object sender, EventArgs e)
        {
            timer1.Enabled = true;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            textBox1.Text = MyValue.ToString();
        }
    }

Additional information:
OpcLabs.QuickOpc 5.52.91 (from Nuget)
.NET Framework 4.6.1
Microsoft Visual Studio Enterprise 2017 Version 15.6.1

Thank you,
Jan
