web-services - Azure System.Web.Services.Protocols.SoapException

Question

我在服务器上使用 Web 服务，它工作正常。现在我想将我的网站转移到 Azure 服务器。目前，我在 azure 上创建了一个免费网站来测试它。

它是一个 Silverlight 应用程序，调用服务来创建报告。

当我调用此服务时，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。

此问题是由于对 Azure 网站实例出于安全和性能原因而限制使用的 API 的访问造成的。 native GDI 渲染方法属于这些受限制的 API 之一。

请参阅 Jim Cheshire 在 this post 末尾发表的帖子。

除非放宽这些限制(也可能不会放宽)，否则您的选择是将服务移至云服务实例，或移至不使用 native GDI 方法进行渲染的另一个组件。
