App.config file <bindingRedirect> problems

I have built an assembly (dll) from which I expect third parties to
subclass. As a result, when my assembly has a version change, it will cause
any third party assembly based on it to break unless I establish a Publisher
Policy file. So I have that.

I have built a Windows app for the same product. This app prompts the user
for a path to a third party assembly that depends on my assembly. It opens
the third party assembly (Assembly.Load) and instantiates some of the
classes it contains. All of this works so long as the versions match between
my assembly and the third party assembly.

Instead of demanding that the user adds my assembly and its publisher policy
file to the GAC, I want my Windows app to offer an application config file
that handles version changes of my assembly. I cannot get this part to work.
Any ideas?

Details:
My assembly name: PeterBlum.VAM.dll, v0.9.2.1. Located in the same folder as
the Windows app. (The publisher policy file and its own config file is also
in the same folder although that doesn't seem to matter.)
Third party assembly name: PeterBlum.PDPToVAM.dll, compiled to use v0.9.2.0.
Windows app name: Import VAM Classes.exe
App config file: "Import VAM Classes.exe.config" located in the same folder
as the exe.
Config file contents:
<configuration>
<runtime>
<assemblyBinding xmlns:asm="urn:schemas-microsoft-com:asm.v1">

<dependentAssembly>
<assemblyIdentity name="PeterBlum.VAM"
publicKeyToken="76d6c019e89ec3c9"
culture=""/>
<bindingRedirect oldVersion="0.9.0.0-0.9.2.0"
newVersion="0.9.2.1"/>

</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>

The Fusion log entry when Assembly.Load("[path]\PeterBlum.PDPToVAM.dll") is
executed:
The operation failed.
Bind result: hr = 0x80131040. No description available.

If you always want to force your users to use the newest version, you may
want to consider keeping the assembly version the same and just changing the
file version, instead. See
http://blogs.gotdotnet.com/suzcook/P...8-65f3eac85274
for other things to consider in that decision.

Hi Adam and Suzanne,

Thanks for both of your responses.

Adam, your idea of using the .Net Configuration Tool was very helpful. I
generated a file that worked and compared it to the file I posted. The
difference was the namespace definition.
I wrote:
<assemblyBinding xmlns:asm="urn:schemas-microsoft-com:asm.v1">
It should have been:
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
I'm not sure where I picked up the "asm" part.

Hey Peter,

Is this an app.config file that you built manually or did you let the
net configuration tool build this file for you? I have had some difficulty
when building this file myself, only to find that letting the .net
configuration tool build it for me not only works, but is much quicker.

Let me know if you still have problems.
