I need to upgrade our web services to use WCF instead of ASMX. If the signatures of the web services stays the same, will existing clients that already call the ASMX service ha
If you use the BasicHttpBinding
for your new WCF service, and implement the same methods with the same message structure, existing callers should be able to call into this new WCF service without any change on their part.
There's also an AspNetCompatibilityRequirements
attribute in order to get around some potential compatibility issue - see the MSDN documentation on it.
