bindingRedirect and COM-interop
- From: "Thomas Israelsen" <ti@xxxxxxxxxxx>

I have two different versions of an assembly (3.2.3.0 and 3.3.0.0).
Both are registered for com-interop (by building them with Visual
Studio). They are in separate directories.
I have an unmanaged executable which I want to have use the older
version (3.2.3.0) of the assembly via com-interop. I've verified that
two separate keys are present under InprocServer32 in the registry -
one for each version of the assembly. Under each of these keys the
correct codebase value is present.
My executable is CppTestClient.exe, so I created
CppTestClient.exe.config and placed in the same directory. The file
looks like this:
<?xml version ="1.0?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="FleetViewClient"
publicKeyToken="5ba74f079946f741"/>
<bindingRedirect oldVersion="3.3.0.0"
newVersion="3.2.3.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
When I run the executable it fails, since it expects to find a method
which is not present in the newer assembly (I assume).
The logs from FUSLOGVW.exe (see below) suggest that the config-file is
ignored, since they look the same whether the config-file is there or
not. If i try using the config file on a managed executable, the
redirection works like a charm.
I think it's supposed to work with unmanged executables. Phil Wilson
has a section on it in his execellent book "Definitive guide to Windows
Installer" and this article also describes it:

Any suggestions?
