I am trying to add web reference when adding web reference url in windows application it shows error like this. how do i solve it?
There was an error downloading 'http://www.example.com/BackEndWebService/LoginWebService.asmx/$metadata'.
The request failed with the error message:
$metadata Web Service method name is not valid.

I had the same issue the other day when tried to update the web reference and managed to fix it by adding ?WSDL at the end. That should work.
