I've an existing web application and I'm trying to add a new webservice to
it. I'm using VS.NET, ASP.NET/C# and Framework 1.0. I added a new web
service into a sub-folder in the UI project and created a new webservice in
it and modified the namespace so that the webservice and the webapplication
gets compiled into one assembly. In IIS I made the sub-folder containing the
new webservice into an Application and copied the respective dlls into a bin
folder under this sub-folder. When I try to access the webservice via the
browser it gives me the error mentioned below. If I append '?wsdl' to the
URL, it generates the service description fine but If I try using wdsl.exe
to generate a proxy it gives me the same error as below. Am I missing
anything? Any kind of help will be appreciated. Thanks.
