Azure System.Web.Services.Protocols.SoapException

Question

我在服务器上使用web服务，它工作正常。现在，我要将我的站点传输到Azure服务器。现在我在azure上创建了一个免费的网站来测试它。

它是一个调用服务来创建报告的Silverlight应用程序。

当我调用此服务时，会出现以下错误

错误：

根据提供的堆栈跟踪，您似乎正在尝试从服务器上的ComponentOne运行报告工具。

该问题是由于访问Azure网站实例出于安全和性能原因而被限制使用的API造成的。原生GDI呈现方法是这些受限的API中的一种。

请看Jim Cheshire在this post末尾的帖子。

在这些限制放松之前(可能不是)，您的选择是将服务移动到云服务实例，或者移动到不使用本地GDI方法进行呈现的另一个组件。
