对我来说，我的问题是我有两个相同的NuGet包安装了不同的版本。

对我来说，问题在于没有强名称的NuGet包。解决方案是从NuGet安装StrongNamer，它会自动向所有引用的程序集添加强名称。只是简单地在项目中引用它修正了我的问题。

我正在寻找解决同样问题的解决方案，取消“签署程序集”选项对我有用:

(正如你可能注意到的，截图来自Visual Studio 2010，但希望它能帮助到一些人。)

如何对未签名的第三方程序集进行签名

Open up Developer Command Prompt for Visual Studio. This tool is available in your Window programs and can be found using the default Windows search. Ensure your prompt has access to the following tools by executing them once: sn ildasm and ilasm Navigate to the folder where your Cool.Library.dll is located sn –k Cool.Library.snk to create a new key pair ildasm Cool.Library.dll /out:Cool.Library.il to disassemble the library move Cool.Library.dll Cool.Library.unsigned.dll to keep the original library as a back-up ilasm Cool.Library.il /dll /resource=Cool.Library.res /key=Cool.Library.snk to reassemble the library with a strong name powershell -command "& {[System.Reflection.AssemblyName]::GetAssemblyName($args).FullName} Cool.Library.dll" to get the assembly fully qualified name. You will need this bit if you have to reference the DLL in external configuration files like web.config or app.config.

I had this issue for an app that was strongly named then had to change it in order to reference a non-strongly named assembly, so I unchecked 'Sign the assembly' in the project properties Signing section but it still complained. I figured it had to be an artifact somewhere causing the problem since I did everything else correctly and it was just that. I found and removed the line: [assembly: AssemblyKeyFile("yourkeyfilename.snk")] from its assemblyInfo.cs file. Then no build complaints after that.

如@Michal Stefanow所说，删除“Signing”选项卡下的“Sign the assembly”复选标记。

Add here是为自己的文件和/或其他人的文件签名的最简单方法。你只需要在“Post-build event命令行”下添加这一行:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\signtool.exe" sign /f "$(ProjectDir)\YourPfxFileNameHere.pfx" /p YourPfxFilePasswordHere /d "Your software title here" /du http://www.yourWebsiteHere.com /t http://timestamp.verisign.com/scripts/timstamp.dll /v "$(BaseOutputPath)$(TargetFileName)"

你可以给别人的文件签名，也可以给自己的文件签名，想签多少都行。
