Microsoft.AspNetCore.Hosting.Abstractions 清单定义与程序集引用不匹配

Question

当我在类库中运行 Entitfy 框架核心命令 add-migration MyMigrationName 时，出现以下错误

无法加载文件或程序集 'Microsoft.AspNetCore.Hosting.Abstractions，版本=1.1.1.0， Culture=neutral, PublicKeyToken=adb9793829ddae60' 或其其中之一 依赖关系。定位程序集的清单定义不 匹配程序集引用。 （HRESULT 异常：0x80131040）

有趣的是，我的应用程序中没有提到抽象。

这是我的 csproj

  <Project Sdk="Microsoft.NET.Sdk">

为了让 NuGet 将适当的绑定重定向添加到类库项目，您需要将以下内容添加到您的 *.csproj 文件中。

<PropertyGroup>
  <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
  <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
</PropertyGroup>
