Msbuild Postsharp抛出System.Runtime.InteropServices.COMException（0x8013141C）：未找到强名称密钥容器。（来自HRESULT的异常：0x8013141C）

为将来需要解决相同问题的任何人添加问题

环境：Visual Studio 2017或2019
对程序集进行Postsharp签名时出现生成错误

我在尝试使用（SN.exe）创建新签名密钥时，遇到访问被拒绝的错误，因此我能够解决此问题

sn -k jeff.snk
Failed to generate a strong name key pair -- Access is denied.

使用显示问题是对

C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys

中特定文件的访问被拒绝。在授予自己对目录中所有文件的访问权限后，我能够创建签名密钥并运行msbuild，没有任何错误。

我发现McAfee防病毒有时会阻止此访问。Postsharp的技术支持论坛网站规避AV是其失败的唯一原因
