【问题描述】：

当我构建我的 asp.net core 2.2 应用程序时，我收到一条警告说

 There was a conflict between "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60" and "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60".
 "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60" was chosen because it was primary and "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60" was not.
 References which depend on "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60" [/Users/yurypastushenko/.nuget/packages/microsoft.aspnetcore.hosting.server.abstractions/2.0.0/lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Server.Abstractions.dll].
     /Users/yurypastushenko/.nuget/packages/microsoft.aspnetcore.hosting.server.abstractions/2.0.0/lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Server.Abstractions.dll
       Project file item includes which caused reference "/Users/yurypastushenko/.nuget/packages/microsoft.aspnetcore.hosting.server.abstractions/2.0.0/lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Server.Abstractions.dll".
         /Users/yurypastushenko/.nuget/packages/microsoft.aspnetcore.hosting.server.abstractions/2.0.0/lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Server.Abstractions.dll
 References which depend on "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60" [].
     /Users/yurypastushenko/.nuget/packages/microsoft.aspnetcore.hosting.abstractions/2.0.3/lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Abstractions.dll
       Project file item includes which caused reference "/Users/yurypastushenko/.nuget/packages/microsoft.aspnetcore.hosting.abstractions/2.0.3/lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Abstractions.dll".
         Microsoft.AspNetCore.Hosting.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60

注意References which depend on "Microsoft.AspNetCore.Hosting.Server.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60" 后面的空列表 []。

这是否意味着我没有参考 2.0.3 版？那为什么会发生这种引用冲突呢？

有人遇到过类似的问题吗？

【问题讨论】：

你的项目中有哪些nuget 包？

帕维尔，感谢您的评论。在尝试回答时，我在 .csproj 文件中遇到了两个引用：

    <ItemGroup>
      <Reference Include="Microsoft.AspNetCore.Hosting.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60">
        <HintPath>..\..\..\.nuget\packages\microsoft.aspnetcore.hosting.abstractions\2.0.3\lib\netstandard2.0\Microsoft.AspNetCore.Hosting.Abstractions.dll</HintPath>
      </Reference>
      <Reference Include="Microsoft.Extensions.DependencyInjection.Abstractions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60">
        <HintPath>..\..\..\.nuget\packages\microsoft.extensions.dependencyinjection.abstractions\2.0.0\lib\netstandard2.0\Microsoft.Extensions.DependencyInjection.Abstractions.dll</HintPath>
      </Reference>
    </ItemGroup>

我不知道他们是如何到达那里的，但显然他们是冲突的原因。删除它们后，所有内容都会编译而不会发出警告。
