How to fix .Net Runtime unhandled exception

asynchronous c# entity-framework entity-framework-core wpf

Question

I had a function which I need to Refresh the data grid view. When I deploy the program it automatically close the program.

I have a MSSQL Server in my side. I tried to fix my function several times but it only works fine in my environment.

Here is my code.

private async void RefreshDataGrid()
        {
            Console.Write(_workstation);

            bool uiMarshal = DGView.InvokeRequired;
            var cards = (from view in _database.RandomCheckViews
                        where view.Workstation == _workstation
                        && view.Client_Name == _clientName
                        orderby view.ID
                        select view).ToList();
            if (uiMarshal)
            {
                DGView.BeginInvoke(new MethodInvoker(delegate
                {
                    DGView.DataSource = cards;
                    DGView.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;

                    foreach (DataGridViewRow cardData in DGView.Rows)
                        if (cardData.Cells["Result"].Value.ToString() == "Failed")
                            cardData.DefaultCellStyle.BackColor = Color.Red;

                    DGView.Refresh();
                }));
            }
            else
            {
                await Task.Delay(1000);
                await Task.Run(() => DGView.DataSource = cards);
                await Task.Run(() => DGView.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells);

                foreach (DataGridViewRow cardData in DGView.Rows)
                    if (cardData.Cells["Result"].Value.ToString() == "Failed")
                        cardData.DefaultCellStyle.BackColor = Color.Red;
                await Task.Run(() => DGView.Refresh());
            }
        }

After I checked several times on our deployment pc, here what I got on Windows Event Viewer.

had a similar problem some time ago, if i remember correctly it was a problem with async void, which you are using aswell.

Try with using a Task

private async Task RefreshDataGrid()
