Visual Studio: Service Reference dialog will not open

Even without selecting a WSDL, if I click on the Advanced button on the Add Service Reference dialog in Visual Studio 2008 on a specific project, I开发者_如何学JAVA get the following error:

An error occured while parsing EntityName. Line 2, position 47.

Anyone run into this before?

this must be problem of your webservice class, there might be some errors in that.

The WSDL published from the server may be broken, you may try the command line tool (svcutil) to test it, though the VS uses the same tool indeed.
