我只是有这个警告消息，清理解决方案和重新编译(构建->清洁解决方案)，它消失了。

我只是有这个警告消息，清理解决方案和重新编译(构建->清洁解决方案)，它消失了。

如果使用NuGet，我所要做的是:

右键单击项目，单击管理NuGet包.. 点击右上角的齿轮 在包源上方的NuGet包管理器中单击“常规”选项卡 检查“跳过应用绑定重定向”在绑定重定向 清理重建，警告就没了

容易peasy

此警告意味着两个项目引用相同的程序集(例如System.Windows.Forms)，但这两个项目需要不同的版本。你有几个选择:

Recompile all projects to use the same versions (e.g. move all to .Net 3.5). This is the preferred option because all code is running with the versions of dependencies they were compiled with. Add a binding redirect. This will suppress the warning. However, your .Net 2.0 projects will (at runtime) be bound to the .Net 3.5 versions of dependent assemblies such as System.Windows.Forms. You can quickly add a binding redirect by double-clicking on error in Visual Studio. Use CopyLocal=true. I'm not sure if this will suppress the warning. It will, like option 2 above, mean that all projects will use the .Net 3.5 version of System.Windows.Forms.

这里有几个方法来识别不合适的推荐人:

您可以使用一个实用程序，例如在 https://gist.github.com/1553265 另一个简单的方法是设置Build 输出冗长(工具，选项，项目和解决方案，构建和 运行，MSBuild项目构建输出详细，详细)之后 构建时，在输出窗口中搜索警告，并查看 文字就在上面。(向保罗亚致敬，她在 对这个答案的评论)。

I just spent sometime debugging the same issue. Note, that issue might not be between different projects, but actually between several references in one project that depend on different versions of the same dll/assembly. In my case, issue was reference FastMember.dll versions mismatch that comes from two different NuGet packages in a single project. When I was given a project, it would not compile because NuGet packages were missing and VS refused to restore missing packages. Through the NuGet menu, I manually update all the NuGets to the latest version, that is when the warning appeared.

在Visual Studio工具中>选项>构建和运行> msbuild项目构建输出详细信息:(设置为)诊断。在“输出”窗口中查找有冲突的行。下面是我得到的输出部分:

1>  There was a conflict between "FastMember, Version=1.5.0.0, Culture=neutral, PublicKeyToken=null" and "FastMember, Version=1.3.0.0, Culture=neutral, PublicKeyToken=null". (TaskId:19)
1>      "FastMember, Version=1.5.0.0, Culture=neutral, PublicKeyToken=null" was chosen because it was primary and "FastMember, Version=1.3.0.0, Culture=neutral, PublicKeyToken=null" was not. (TaskId:19)

注意，该项目文件项包括导致引用“C:\Users\ksd3jvp\Source\Temp\AITool\Misra\AMSAITool\packages\ClosedXML.0.94.2\lib\net46\ClosedXML.dll”

ClosedXML.dll来自ClosedXML NuGet，它依赖于FastMember.dll 1.3.0.0。在它之上，项目中还有FastMember Nuget，它有FastMember.dll 1.5.0.0。不匹配!

我已经卸载了ClosedXML和FastMember NuGets，因为我有绑定重定向，并安装了ClosedXML的最新版本，解决了这个问题!

我也有同样的问题，我通过在web.config中更改以下内容来解决。

这发生在我身上，因为我正在使用Newtonsoft运行应用程序。Json 4.0
