推荐答案

将您的 Visual Studio 2013 从更新 2 升级到更新 4.当您构建项目时，它会给出有关 Hyper-V 网络适配器的错误.要解决此问题，请通过单击提示中的重试"按钮来更改 Hyper -V 网络适配器设置.(您也可以将Window phone SDK升级到8.1以获得更好的体验.可选，无需解决此错误.)

Upgrade your Visual Studio 2013 from Update 2 to Update 4. When you Build your project it gives and error about Hyper - V Network adapter. To Solve that, allow to change in Hyper -V Network Adapter settings by click on "Retry" button in prompt. ( You can also upgrade Window phone SDK to 8.1 for better experience. It is optional not necessary to solve this error.)
