Visual Studio 2015开发Android App 启动调试始终无法完成应用部署的解决方案
创建一个Android App项目后，直接启动调试发现Visual Studio Emulator for Android已成功运行，但应用始终处于Build中（等待时间超过1小时），并未如预期通过adb部署到模拟器中。将应用直接导出apk，拖拽至模拟器直接部署，提示：
File transfer failed. Error: Unable to install the file through Adb. Adb.exe not found. Make sure you have Android SDK Tools installed.查看进程列表发现adb.exe已经启动，并且和Visual Studio有通信，但XDE和adb.exe没有通信。应该是XDE无法定位Android SDK路径所致。于是运行Process Monitor，再次尝试拖拽apk，终于发现XDE查找名为"HKCU\Software\Microsoft\VisualStudioEmulator\Android\AdbPath"的注册表键值，添加对应的键值问题解决。怀疑和我并没有通过Visual Studio直接安装Android SDK有关系，导致一些设置无法生效。

Visual Studio 2015开发Android App 无法附加断点 Could not connect to the debugger.
I had same issue and I was able to connect debugger by following this:
http://dotnetbyexample.blogspot.cz/2016/02/fix-for-could-not-connect-to-debugger.html
In short:
Disable "Use fast deployment (debug mode only)" in Android project -> Properties -> Android options -> Packaking
Enable "Migrate to a physical computer with a different processor version" in Hyper-V manager go to VM -> Settings -> Processor -> Compatibility
