WCF Integration Facility throws exception: cannot load System.ServiceModel

[Uri Goldstein]

Hi,

Might anyone know why the following exception is thrown when using the
WCf Integration Facility:

"Could not load file or assembly 'System.ServiceModel' or one of its
dependencies. The system cannot find the file specified. "

I'm not sure but I suspect this is related to my trying to inject an
IServiceBehavior with the facility.

Only if I set CopyLocal=true on the reference to System.ServiceModel
in my project does the exception go away. I assume the DLL is in the
GAC so why couldn't the WCF Integration Facility find it?


Thanks,
urig

use fuslogvw and see what is the real problem

Hi Krzysztof, thanks for your help.

I've ascertained that this only happens when I try to register an
IBehavior to be injected through the Wcf Integration Facility like so:

<component id="myUserNameCredential"
service="System.ServiceModel.Description.IServiceBehavior,
System.ServiceModel" type="Common.MyUserNameCredential, Common" />

I couldn't quite get fuslogvw.exe to "catch" the bind error. Instead
I'm supplying the text of the server error that I receive from IIS:

Is your app compiled against .NET 3.5 SP1?

Yes. I'm compiling with .Net 3.5 SP1 (on Windows XP SP3).

Here is what fuslogvw.exe has to say, now that I've switched from
using WebDev.exe to IIS 5.1:

This is an old post but thought I would weigh in since my company is still kicking it old school with XML component registration over installers. In our case we used partial assembly name for System.ServiceModel as the O.P. did here. For whatever reason, this consistently fails. Oddly, fuslogvw provides a warn instead of an error for this scenario. So moral of story is use fully qualified assembly name for System.ServiceModel when registering WCF components such as IServiceBehavior and IErrorHandler.

Ex:

System.ServiceModel.Description.IServiceBehavior, System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
