在Android设备上进行调试时，无法再设置/使用断点 [英] Can't set/use breakpoints anymore, when debugging on Android device

问题描述

我想在Android设备上调试Xamarin.Forms应用.如果设置断点，我会从Visual Studio中收到以下错误消息:

I want to debug a Xamarin.Forms app on an Android device. If I set a breakpoint I get this error message from Visual Studio:

这是控制台的输出

如果我未设置任何断点，则该应用程序似乎可以正常运行.我的代码有问题吗?我正在使用最新的Xamarin.Forms(2.3.4.247).

If I don't set any breakpoints the app seems to work normally. Is there something wrong in my code? I'm using the latest Xamarin.Forms (2.3.4.247).

推荐答案

似乎使用 portable作为DebugType 导致了这些问题.现在，我将其还原为full，并且目前似乎可以使用.

Seems that using portable as DebugType was causing these issues. Now I reverted it back to full and it seems to work for now.
