Remoting serialization fails with custom object

Hi,

I have a client application that is using remote objects from a IIS.

Everything works fine when using this from my code.

However. When a word add-in loads my code the request fails with a message
that it can not find the a assembly.

The assembly in question is one that is referenced in the servercode and on
the client, they both have the same version.


Summary; it works when I run it in my fixture, not when my code is called
from a application. And the assembly in question exists in THAT codes /bin
directory.

Can Anyone say anything I would be really gratefull.

Regards Greger

The method call fails with:

System.Runtime.Serialization.SerializationException occurred

Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'."

Hi


I think I know what going on but not how to solve it.

The process is started from a different app domain and that
appdomain has no clue about the type im trying the get via remoting.

Is it possible to find a way to hook in a SerializationBinder or similar?

Any other solution to this problem?

Have you had any luck with this? I have exactly the same problem with a
shell extension that is using remoting to call a server process.
 
Hi,


Yes the solution is to add a config file to the executing process, in my
case winword.exe.config.
This config makes the executing process aware of the dll's it must be aware
of.
Like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Handelsbanken.AUTO.BusinessData"/>
<codeBase version="1.0.0.0" href="C:\Program Files\Clarity
Workflow\AUTO\bin\Handelsbanken.AUTO.BusinessData.dll"/>
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Handelsbanken.ADIC.BusinessData"/>
<codeBase version="1.0.0.0" href="C:\Program Files\Clarity
Workflow\AUTO\bin\Handelsbanken.ADIC.BusinessData.dll"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>



Hope this helps!
