using Enterprise Library 4.1 Logging Block in Custom Workflow Acti

[dominik_hug]

Hi all

I want to use the Enterprise Library 4.1 Logging Block to make the tracing
in a Custom Workflow Activity (CWA).
I have written a CrmAsyncService.exe.config as configuration file (reading
settings out of this file from a CWA works.

In the project I referenced the
Microsoft.Practices.EnterpriseLibrary.Logging.dll with "Copy Local" set to
true. In the Windows Explorer in the properties of the assembly I can see
that it is a signed assembly.

I copied the assembly Microsoft.Practices.EnterpriseLibrary.Logging.dll
along with
Microsoft.Practices.EnterpriseLibrary.Common.dll
Microsoft.Practices.ObjectBuilder2.dll
Microsoft.Practices.Unity.dll
in the bin\assembly folder of CRM.

But every time the CWA ist executed I have the following error in the trace
output of CRM:

I also tried to move the Enterprise Library Assemblies in the GAC, but it
didn't solve the problem.

The assembly "Microsoft.Practices.EnterpriseLibrary.Logging.dll" in the
bin\assembly folder has the expected public key token (31bf3856ad364e35)

Does anyone have experience with this?

Thanks for help!!!

I found the solution my self:

Adding
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="assembly"/>
</assemblyBinding>
</runtime>
to the CrmAsyncService.exe.config helped.
Interestingly in the Plugins and CustomWorkflowActities I also reference an
assembly
I developed my self and the calling assembly managed to locate it (without
the probing element).
