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

我在使用NuGet安装的ServiceStack DLL文件时遇到了这个问题。原来还有另一组标记为已签名的DLL文件可用。这不是每个人的答案，但您可能只需要检查程序集的现有签名版本。

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。

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.
