.net核心參考與幻影程序集版本沖突

Question

當我構建asp.net core 2.2應用程序時，出現警告信息

 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.

       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

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

這是否意味着我沒有對版本2.0.3的引用？ 那么為什么會發生這種引用沖突呢？

有人遇到過類似的問題嗎？

Answer 1

帕維爾，謝謝您的評論。 在嘗試回答時，我在.csproj文件中遇到了兩個引用：

    <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>

我不知道他們是如何到達那里的，但顯然是沖突的原因。 刪除它們后，所有內容都會編譯而不會發出警告。
