Question

目前正在尝试从ASP .NET 5 MVC 6的beta 6升级到beta 7。我按照此处详述的步骤进行了操作：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，但不幸的是与我的项目不符。

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，但我的列表中没有它。

我的项目有几个部分有时互相引用。装配问题发生在其中两个中，我认为它是链接的，因为每个错误出现8次。

以下是两个的project.json：

我试图删除一些软件包，运行dnu恢复以查看错误是否仍然存在且始终存在，所以我开始没有想法......

Answer 1

在没有看到整个项目的情况下很难分辨，但我猜测第二个JSON片段来自你的库。我的猜测是，这是导致错误的库，而且只会报告到您的Web应用程序中。

以下是一些想法：

将您的框架：dnx451：依赖项移动到框架中：dnx451：frameworkAssemblies。
删除那些System。*包中的 -beta 标识（尝试抓取Nuget包而不是使用本地系统库的可能性很小）
将System。*版本号更改为“4.0.0.0”
切换到较不详细的参考语法（即删除“version”和“type”，只需在引号中指定类似“System.Linq”：“4.0.0.0”）
删除Microsoft.CSharp

Answer 2

I ran into this issue when I had added a class library to a web project. When I added the class library the project.json file frameworks looked like this ...

  "frameworks": {
    "dotnet": { }
  }

When I matched the frameworks of my web application the error was resolved.

  "frameworks": {
    "dnx451": { },
    "dnxcore50": { }
  }
