DevExpress export GridView to Excel on .net6 'System.ComponentModel.Win32Exception'

Question

I use this code to export gridview to excel on .Net Framework 4.7.2 without any problem

        using (XtraSaveFileDialog saveDialog = new XtraSaveFileDialog())
        {
            saveDialog.Filter = "Excel (2007-2019) (.xlsx)|*.xlsx";
            saveDialog.FileName = Resources.dailyProductionPaint;
            if (saveDialog.ShowDialog() != DialogResult.Cancel)
            {

                XlsxExportOptionsEx options = new XlsxExportOptionsEx();
                options.LayoutMode = DevExpress.Export.LayoutMode.Table;
                string exportFilePath = saveDialog.FileName;
                options.BeforeExportTable += ea =>
                {
                    ea.Table.Style.Name = XlBuiltInTableStyleId.None;
                };
                gridControl2.ExportToXlsx(exportFilePath, options);

                if (File.Exists(exportFilePath))
                {
                    try
                    {
                        //Try to open the file and let windows decide how to open it.
                        System.Diagnostics.Process.Start(exportFilePath);
                    }
                    catch
                    {
                        String msg = Resources.openFileEr + Environment.NewLine + Environment.NewLine + Resources.path + exportFilePath;
                        XtraMessageBox.Show(msg, Resources.error, MessageBoxButtons.OK, MessageBoxIcon.Error);
                    }
                }
                else
                {
                    String msg = Resources.saveFileEr + Environment.NewLine + Environment.NewLine + Resources.path + exportFilePath;
                    XtraMessageBox.Show(msg, Resources.error, MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
            }
        }

but when I run the same code on .net6 I get this error

System.ComponentModel.Win32Exception: 'An error occurred trying to start process 'C:\Users\TestUser\Desktop\Daily Result-Painting7.xlsx' with working directory 'C:\Users\TestUser\Desktop'. The specified executable is not a valid application for this OS platform.'

Answer 1

I get the answer from github thanks to kirsan31

Process.Start(new ProcessStartInfo(exportFilePath) { UseShellExecute = true });

In Core UseShellExecute property is set to false by default.
