Hi,

I'm having trouble figuring out what the specifics are. Is this a service
that you upgraded to 1.1 and now the existing 1.0 clients are broken? Or
did you upgrade the client machines to 1.1 and not the server machines and
not the clients are broken?

Have you tried refreshing the generated service proxies? This will
probably fix your issue. If you are not able to do this then you are
probably going to have to keep things stable. To understand what has
changed, I'd suggest comparing the WSDL contracts for the two situations
(assuming it was the machine that the service runs on that was upgraded.)
Unless the two contracts are the same.

If I read you right though, the service side has not changed, but you have
upgraded the .NET version on the machine that makes the call. Try
refreshing the proxy and recompiling. This should fix the issue. The only
other option you have is to add policy statements to the web.config for
this app that make it load the assemblies needed by the app with 1.0.

I hope this helps

I have a working client-side Vb.Net (.net v1.0) app that talks to a
Webspere
webservice on a windows 2000 server. The client side app runs on a citrix
server, also a Windows 2000 server. The app worked ok till I installed .Net
v1.1 on the citrix, now I get an error when I get the app to use .NET v1.1.
 
If the app uses .NET v1.0 (with .NET v1.1 stalled), then its ok, however I
must use v1.1 for other reasons.

Has somebody come across this error before - I am pulling out my hair on
this one.

  The error I get is:

The request was aborted: The request was cancelled. as
system.Net.ConnectStream.CloseInternal(Boolean internalCall, Bollean
ignoreSuhtDownCheck)
at System.Net.ConnectStream.CloseInternal(Boolean internalCall)

at Stste.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String
methodName, Object[] parameters)
at GTPSMessagingLib.GTPSRouterService.process3ParmRequest(string
inputHeaderer, String messageControlPayload, string inputMessage)

The proxy class I use in the app is:
