C# 无法加载Microsoft.Extensions.DependencyInjection.Abstractations 2.2.0版本程序集

当我尝试加载Microsoft.Extensions.DependencyInjection.Abstractions的2.2.0版本时，出现以下错误。我的.net核心web应用程序总是试图加载

2.1.0

程序集。所有部件参考均指向

2.2.0

版本。请查找下面的加载错误

无法加载文件或程序集“Microsoft.Extensions.DependencyInjection.Abstractions，Version=2.1.0.0，Culture=neutral，PublicKeyToken=adb9793829ddae60”或其依赖项之一。定位的程序集清单定义与程序集引用不匹配。（来自HRESULT:0x8013100的异常）”：“Microsoft.Extensions.DependencyInjection.Abstractations，版本=2.1.0.0，区域性=neutral，PublicKeyToken=adb9793829ddae60

Ware您有什么。NETCore2.x应用程序？3.x？某些程序集可能有对它的引用，请尝试在解决方案视图中搜索Microsoft.Extensions.DependencyInjection.Abstractions它显示所有依赖它的包。如果是.NET Core 2.2应用程序，您是否安装了.NET Core 2.2 SDK/运行时？能否显示您的

.csproj

文件？谢谢您的回复，我已经在解决方案视图中搜索了Microsoft.Extensions.DependencyInjection.Abstractions，但在任何地方都显示了2.2.0版本的程序集。我正在.net framework 4.8 web项目中使用.net core 2.2程序集。请确保所有csproj文件都使用

项目，而不是package.config模型。此问题通常在使用旧的package.config model.Btw时发生。请注意，对.NET Core 2.2组件的支持将于2019年12月23日结束，您将无法在.NET Framework上升级到3.0。您必须降级到2.1才能继续支持.NET Framework。
