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

Question

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

无法加载文件或程序集 'Microsoft.AspNetCore.Hosting.Abstractions， version=1.1.1.0， Culture=中性，公钥令牌=adb9793829ddae60'或其之一 依赖。找到的程序集的清单定义没有 匹配程序集引用。(HRESULT的例外：0x80131040(

有趣的是，我的应用程序中没有引用抽象。

这是我的csproj

<PropertyGroup Label="Globals">

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

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