Compatibility between 1.1 and 2.0

[styxke]

Hi all,

I have ported my webservice from .NET1.1 to .NET2.0 but my applications work with a reference file for the 1.1 version (and it's not possible to recompile all existing applications). When I put the 2.0 version online, the applications generate an error like "Soap header not understood" (don't know the exact error, can't look it up now) when trying to communicate with the web service. The web service hasn't changed, it has just been ported.

Is there a way to let the old applications communicate with the new webservice?

Thanks in advance.

Greets,
Philipp

They are compatible, make sure your web service namespace is the same. When testing this scenario I get error similar to what you describe when using different namespaces:

System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction:<namespace qualified method called>

That was indeed the problem.

Thanks!
