如何在Xamarin表单中以十字图形式在后台运行App [英] How to Run App in Background in Xamarin forms Cross plotform

问题描述

我已经开发了xamarin跨平台应用程序，并且在iOS和Android版本中都可以正常工作.

I have developed a xamarin cross platform application and it is working fine in both iOS and Android versions.

现在，我们需要添加一个新功能，例如即使应用程序已关闭，我们也需要在后台运行应用程序.我需要每5分钟向用户发送一封电子邮件.
我对xamarin非常陌生，请问有什么可以帮助我实现这一目标的.

Now we need to add a new feature like we need to run app in background even app is closed. I need to send emails to the users for every 5 minutes.
I am very much new to xamarin Can any help me out to achieve this please.

最好的问候，斯里尼瓦斯.

Best Regards, Srinivas.

推荐答案

后台服务(当应用程序处于后台模式但未关闭时)是您的解决方案，请看一下:

Background services (when app is in a background mode, not closed) is your solution, take a look:
