C# .net核心引用与虚拟程序集版本冲突

当我构建我的asp.net core 2.2应用程序时，会收到一条警告，上面写着

 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.

         Microsoft.AspNetCore.Hosting.Abstractions, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60

请注意，

引用后的空列表[]，它依赖于“Microsoft.AspNetCore.Hosting.Server.Abstractions，Version=2.0.3.0，Culture=neutral，PublicKeyToken=adb9793829ddae60”

这是否意味着我没有参考版本2.0.3？那么为什么会发生这种引用冲突呢

有人遇到过类似的问题吗

Pavel，谢谢你的评论。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>

我不知道他们是如何到达那里的，但很明显，他们是冲突的原因。删除它们后，所有内容都会编译，不会出现警告。
