I had created several web services with WebMethods that returned DataSets. I attempted to import these services into MSE and got this error:
...Message[An error occurred while savingSchema and Objects for Import [Exception Information Type[XmlSchemaException]Source[System.Xml] Message[The 'http://www.w3.org/2001/XMLSchema:schema'element is not declared.]...
I converted my DataSets to XmlDataDocuments and was able to successfully import the web services. Has anyone else run into this? Are DataSets not supported?
