证书存储访问被拒绝

我收到 System.Security.Cryptography.CryptographyException 访问被拒绝。当尝试创建媒体服务任务或作业时。该应用程序在天蓝色网站实例上运行。一切都在本地进行。看起来该应用程序无法写入证书存储。我尝试将应用程序的信任级别提升到完全，但没有效果。

    System.Security.Cryptography.CryptographicException: Access is denied.

Edit我已将应用程序移至虚拟机，但仍然收到相同的异常

在 IIS7 上运行时 - 您可以指定加载应用程序池的用户配置文件。这使您可以访问应用程序池帐户的每个用户存储。

这就是您对 Windows Azure 网站的期望。您与其他网站一起在共享环境中运行，出于安​​全原因，您无法执行许多操作。

如果您希望完全控制托管 Web 应用程序的计算机（例如对证书存储的完全访问权限、在注册表中进行更改……），您应该将应用程序部署到 Web 角色。
