You mentioned at the bottom of this article that you had some other problems with .net applications and the SSRS web service. I have just upgraded to 2008 and we are having some problems with rendering a report from a .net application. We have found that the wsdl reference is different and the methods are also different. We now have it working from within VisualStudio. But, when we try to run the application under IIS we get the following error Message : Client found response content type of '', but expected 'text/xml'. Any ideas?
