.net – 包恢复失败.回滚包更改 – Serilog.AspNetCore

但是,当我试图添加“Serilog.AspNetCore”软件包版本2.0.0时,我正在“

Package restore failed. Rolling back package changes for ‘BackEnd’.

我的csproj包含以下设置：

<PropertyGroup>
   <TargetFramework>netcoreapp2.0</TargetFramework>
   <DockerComposeProjectPath>....docker-compose.dcproj</DockerComposeProjectPath>
   <AssemblyName>BackEnd</AssemblyName>
  <RootNamespace>BackEnd</RootNamespace>
</PropertyGroup>

Allready已经尝试清除所有nuget缓存,重建,重启VS.

在Win10上运行,Visual Studio 2017 15.3.0

是否有日志可以提供更多详细信息,为什么我收到此错误？
任何建议如何解决？
