使用Visual Studio 2017进行Xamarin表单

Question

我是Xamarin的新手，并在Visual Studio 2017中创建了一个跨平台项目。

当我构建该项目时，我遇到了以下问题：

Severity: Error
Code: MSB4062
Description: The "Xamarin.Forms.Build.Tasks.XamlGTask" task could not be loaded from the assembly C:\Users\E6430\.nuget\packages\xamarin.forms\3.1.0.637273\build\netstandard2.0\Xamarin.Forms.Build.Tasks.dll. Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.
Project: TestApp
File: C:\Users\E6430\.nuget\packages\xamarin.forms\3.1.0.637273\build\netstandard2.0\Xamarin.Forms.targets
Line: 84

我的NuGet也会变成黄色。
