如何找出 Nuget 包中的主要问题

Question

我最近更新了我的包，我开始在一些项目中收到这个奇怪的警告。我无法解决它：

Found conflicts between different versions of "System.Runtime.CompilerServices.Unsafe" that could not be resolved.
There was a conflict between "System.Runtime.CompilerServices.Unsafe, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".

我如何破译这里的实际问题是什么？是否有内部依赖于特定版本 DLL 但该 DLL 也直接添加到较新版本的包？

Answer 1

简而言之，您依赖于同一 DLL 的两个不同版本。下面的细分，但是 TL;DR，您应该能够通过将 PackageReference 更新到 System.Runtime.CompilerServices.Unsafe 到版本 6.0.0.

来解决这个问题

如果您不直接调用它，请考虑删除 PackageReference，因为它应该通过下面列出的其他引用传递地添加。

如果您没有此包的 PackagerReference，添加一个（使用版本 6.0.0）将使它成为主要引用，从而再次将所有内容对齐到同一版本。

错误信息细目：

Found conflicts between different versions of "System.Runtime.CompilerServices.Unsafe" that could not be resolved.
There was a conflict between "System.Runtime.CompilerServices.Unsafe, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".

编译器根据您引用它的直接程度（与引用它的依赖项之一相反）来选择一个：

"System.Runtime.CompilerServices.Unsafe, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was chosen because it was primary and "System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was not.

5.0 版本被引用：

References which depend on "System.Runtime.CompilerServices.Unsafe, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" [C:\Users[=12=]00\.nuget\packages\system.runtime.compilerservices.unsafe.0.0\ref\net461\System.Runtime.CompilerServices.Unsafe.dll].
    C:\Users[=12=]00\.nuget\packages\system.runtime.compilerservices.unsafe.0.0\ref\net461\System.Runtime.CompilerServices.Unsafe.dll

项目中对 5.0 文件创建此运行时依赖项的项目似乎是它本身，即您直接引用它：

Project file item includes which caused reference "C:\Users[=13=]00\.nuget\packages\system.runtime.compilerservices.unsafe.0.0\ref\net461\System.Runtime.CompilerServices.Unsafe.dll".
  C:\Users[=13=]00\.nuget\packages\system.runtime.compilerservices.unsafe.0.0\ref\net461\System.Runtime.CompilerServices.Unsafe.dll

这些依赖项引用了 6.0 版本：

References which depend on "System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" [].
    C:\Users[=14=]00\.nuget\packages\system.memory.5.4\lib\net461\System.Memory.dll
      ...
    C:\Users[=14=]00\.nuget\packages\system.threading.tasks.extensions.6.0-preview.18571.3\lib\netstandard2.0\System.Threading.Tasks.Extensions.dll
      ...

这些是通过其他包间接引用的：

  C:\Users[=15=]00\.nuget\packages\system.memory.5.4\lib\net461\System.Memory.dll
