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。

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.

ilmerge使用。ilmerge来自微软，但它没有随Visual Studio或sdk一起发布。不过你可以从这里下载。还有一个GitHub存储库。你也可以从NuGet安装:

PM> Install-Package ilmerge

使用方法:

ilmerge assembly.dll /keyfile:key.snk /out:assembly.dll /targetplatform:v4,C:\Windows\Microsoft.NET\Framework\v4.0.30319 /ndebug

如果需要，你可以使用sn(从Visual Studio)生成你自己的密钥文件:

sn -k key.snk

我添加了NuGet包“StrongNamer”，我的问题解决了。

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.
