    help! Error: The XML element is already in the current scope...

    "The XML element 'EnableTheming' from namespace 'http://tempuri.org/'
    is
    already present in the current scope"

    I created a Web Service: I imported System.Data.Sql Client so I could
    access SQL server tables programmaticall y. The web service builds and
    deploys with no problems. When I try to add the corresponding Web
    Reference to the Web Site project I get the error listed below.

    I am able to create other Web Services on the same server and I am able
    to add Web Referneces to them. I have narrowed it down to the "Imports
    System.Data.Sql Client" statement, I think. What's up with this?

    I changed tempuri.org to something I have control over and it had no
    effect.

    Thanks,

    Bill

      Re: help! Error: The XML element is already in the current scope...

      Does your schema defines the element EnableThemming twice in the cotent
      model? Can you post your xsd/xml and repro code?

      Thanks,
      Priya

          I'm experiencing the same error. I'm not defining EnableTheming anywhere and no xml is being produced.

          I'm using VS 2005. I have created other web services with no problem. I have not tried narrowing down the offending namespace yet.

              RE: help! Error: The XML element is already in the current scope...

              "The XML element 'EnableTheming' from namespace 'http://tempuri.org/'
              is
              already present in the current scope"
              >
              I created a Web Service: I imported System.Data.Sql Client so I could
              access SQL server tables programmaticall y. The web service builds and
              deploys with no problems. When I try to add the corresponding Web
              Reference to the Web Site project I get the error listed below.
              >
              I am able to create other Web Services on the same server and I am able
              to add Web Referneces to them. I have narrowed it down to the "Imports
              System.Data.Sql Client" statement, I think. What's up with this?
              >
              I changed tempuri.org to something I have control over and it had no
