Question

我正在构建MS Word VSTO加载项。它已成功使用，但在64位Word安装上使用时抛出错误。发生以下堆栈跟踪：

2019-06-05 15:57:17,448 [VSTA_Main] INFO Office.Infrastructure.Word.TaskPaneVisibilityHandler - Using DPI scaling factor: 1

我相信是来自代码：

private bool ConfirmCreateWorkspaceFolder()
        {
            bool isConfirmed = false;

            this.CreateWorkspaceFolderConfirmation.Raise(new TaskDialogConfirmation
            {
                Title = Infrastructure.Properties.Resources.ApplicationName,
                Content = "The selected workspace folder does not exist. Create it now?",
                ConfirmPrompt = "Create folder",
                Type = TaskDialogNotificationType.Warning
            }, c => isConfirmed = c.Confirmed);

            return isConfirmed;
        }

有人可以指出可能发生问题的方向吗？谢谢。
