ASP.Net Core 2.0 - 引用'Microsoft.NET.Sdk.Web'和'PreserveCompilationContext'属性未设置为假

Question

我在_ViewImports.cshtml文件中收到以下错误。

One or more compilation references are missing. Ensure that your project is referencing 'Microsoft.NET.Sdk.Web' and the 'PreserveCompilationContext' property is not set to false.
