在VisualStudio16.9.0Android“部署到设备”错误-命令太长

html5 • • 问答

在我的 xamarin Android 项目中，一切正常，直到我更新到 Visual Studio 2019 v16.9.0。

升级后，我能够成功构建项目，但是如果我尝试部署或调试到设备或模拟器，我会收到以下错误：

任何的想法？

TLDR

我能够通过从Android 项目选项中的Android 选项选项卡中取消选中使用快速部署来解决此问题。

细节

我正在运行 Visual Studio 2019 v16.9。升级之前我没有问题，但上周升级到 16.9 后，我开始遇到这个问题。无论目标模拟器/设备如何，都会发生此错误。

在 Visual Studio 的构建和运行设置中启用诊断构建输出后，我可以在构建输出中看到故障发生在Fast Deploy Application Files期间。

Visual Studio 构建输出

一旦我取消选中快速部署，部署工作正常。我重新打开快速部署并尝试重新部署，但仍然失败。

所以现在我在禁用快速部署的情况下继续开发，到目前为止还没有出现问题。

以上是在VisualStudio16.9.0Android“部署到设备”错误-命令太长的全部内容。
