升级到1.1.0后无法加载文件或程序集"Microsoft.EntityFrameworkCore.SqlServer,Version = 1.1.0.0"

Question

我有一个针对.NET 462的Asp.Net Core项目,它正在使用Asp.Net Core版本1.0.1.升级到"1.1.0"后,我收到此错误:

FileLoadException:无法加载文件或程序集"Microsoft.EntityFrameworkCore.SqlServer,Version = 1.1.0.0,Culture = neutral,PublicKeyToken = adb9793829ddae60"或其依赖项之一.定位的程序集的清单定义与程序集引用不匹配.(HRESULT异常:0x80131040)

},

当我查看构建输出文件夹时,我可以看到除"Microsoft.EntityFrameworkCore.SqlServer"之外的所有库中的正确版本:

我认为这是导致问题的原因.但我只是想不通为什么版本错了？是因为nuget包里面有错误的版本吗？

Answer 1

完整的项目参考清理解决了我的问题.

1. 删除所有bin/obj文件夹
2. 删除所有project.lock.json文件
3. 删除本地Nuget存储库缓存(计算机一)
4. 从project.json文件中删除所有引用并仅添加必需的引用(在R#的帮助下)
5. nuget udpate,dotnet restore =项目正在运行

当我再次考虑它时,也许只有第4点很重要？
