Could not load file or assembly...

Hi,

I am developing a middle tier WCF server called BusinessLogic, using the
Enterprise Library. Although I posted similar question on the EL forums (no
answer yet), it seems to me that the problem is more general .NET related
than WCF or EL specific. The problem shows when EL exception handling block
catches one exception and according to a policy throws different exception:
FaultException<SomeFaultFromBusinessLogic>. When the app. block tries to load
the fault class from BusinessLogic.dll it throws an exception saying that it
cannot find BusinessLogic ver. 1.0.0.2719 but the funny thing is that my
assembly is 1.0.0.1234. No matter what version is the assembly it always
tries to load ver. 1.0.0.2719. Can you please help - this has been haunting
me for weeks now.

Thank you
Val

A first chance exception of type 'Abc.BusinessLogic.FieldNullException'
occurred in BusinessLogic.dll

Start by purging your machine of all the dll's related to that assembly.
Then, perform a clean and then a build. Post back here if you make no
progress.

Alvin,

Thank you for your response. Unfortunately, I have tried that before and
tried it again today and still get the same...

Any other ideas? I'll appreciate it.

Thank you
Val
 
I ran thru the same problem this morning.
After a careful thought, it sounds like both WCF and .Net combination problem.
The server (WCF) was upgraded recently and I was expecting the client to connect to at least some basic services(the first service which lets client to know if it needs to update) and then passes parameters to update. But theWCF service dictates the client to load DLL of the WCF server version, which the client doesn't have. As such exception is throw.

Plans to change the first connecting service, independent of all other DLLs..
Hope this might solve our autoupdate module.
