在 Visual Studio 16.9.0 Android“部署到设备”错误 - 命令太长

如何解决在 Visual Studio 16.9.0 Android“部署到设备”错误 - 命令太长

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

自升级以来，我能够成功构建项目，但如果我尝试部署或调试到设备或模拟器，我收到以下错误：

有什么想法吗？

解决方法

TLDR

通过在 Android 项目选项中的 Android 选项 标签中取消选中使用快速部署，我能够解决此问题。

细节

我运行的是 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失败发生在快速部署应用程序文件。

Visual Studio Build Output

一旦我取消选中快速部署，部署工作正常。我重新开启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。

嗨，只是让你知道我也有这个问题，但自从升级到 16.9.5 后，这似乎又对我有用了，快速部署打勾:)
