"程序定义了多个入口点" Can'找不到其他入口点。

[leod23]

我正在使用Google电子表格API和WPF创建预算应用程序，但出现此错误"程序定义了多个入口点"。谢谢任何能够提供帮助的人。编程很新，所以可能只是我很笨。

WPF应用程序的入口点已生成，可以在App.xaml下找到，请在解决方案资源管理器中不断扩展，直到看到它为止。

在WPF应用程序中，Console.Reads / Writes和使用Main方法非常不常见，这就是您在Console应用程序中要做的事情。

我试图删除该Main入口点，但是没有用。我应该使用App.xaml进行实际编程吗？我要删除哪个入口点？

Delete the Main() that you put in your MainWindow class. WPF is a GUI. Write GUI code.
