c# - ASP .NET 5 MVC 6 beta 7 升级 : "Multiple assemblies with equivalent identity" issue

Question

目前正在尝试将 ASP .NET 5 MVC 6 从 beta 6 升级到 beta 7。我按照此处详述的步骤进行操作:How to upgrade ASP.NET 5 from Beta6 to Beta7但我仍然有程序集问题:

Multiple assemblies with equivalent identity have been imported: '<in-memory-assembly>' and '<in-memory-assembly>'. Remove one of the duplicate references.

This blog提供了一些解决问题的线索，但遗憾的是与我的项目情况不符。

我知道它链接到 project.json 中的包列表。一些解决方案建议使用 Microsoft.Framework.Runtime.Abstractions，但我又一次没有在我的列表中。

我的项目有几个部分，有时会相互引用。其中两个出现装配问题，我认为它是相关的，因为每个错误出现 8 次。

这是两者的 project.json :

    }
}

我已经尝试删除一些包，运行 dnu restore 以查看错误是否仍然存在并且它一直存在，所以我开始没有想法......

如果没有看到整个项目，很难判断，但我猜第二个 JSON 片段来自您的库。我的猜测是您的库导致了错误，并且只是被报告到您的 Web 应用程序中。

这里有一些想法:

• 将您的 frameworks:dnx451:dependencies 移至 frameworks:dnx451:frameworkAssemblies。
• 删除那些 System.* 包中的 -beta 身份(很可能是它试图获取 Nuget 包而不是使用您的本地系统库)
• 将 System.* 版本号更改为“4.0.0.0”
• 切换到不太冗长的引用语法(即删除“version”和“type”，只需在引号中指定版本，如“System.Linq”:“4.0.0.0”)
• 删除 Microsoft.CSharp
