Azure System.Web.Services.Protocols.SoapException

Question

I use a web service on a server and it works OK. Now I want to transfer my site to an Azure server. For now I created a free web site on azure to test it.
It is a Silverlight application that calls a service to create a report.
When I call this service I have the following error
error:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Server</faultcode><faultstring>System.Web.Services.Protocols.SoapException: Server was unable to process request. ---&gt; System.ArgumentException: Parameter is not valid.

Answer 1

Based on the provided stack trace it looks like you are attempting to run report tools from ComponentOne on the server.
The issue is caused by access to APIs that are restricted from use by Azure Web Site instances for security and performance reasons. The native GDI rendering methods are among these restricted APIs.
See the post from Jim Cheshire towards the end of this
post.
Until and unless these restrictions are relaxed (which they may not be) your options are to move the service to a Cloud Service instance, or move to another component that does not use native GDI methods to render.
