Re: "Class not registered" error when assembly registered with multiple versions

Try a bindingredirect from 1.0.2819.34866 to 1.0.0.0. IIRC that should
work. When the framework starts up to look for your assembly I believe it
takes note of redirects in your config file.

Alternatively you need to fix up the CLSID registration entries. There'll
be registration that refers to an assembly version of 1.0.2819.34866 that
you want to change to 1.0.0.0.

Hello!

I have registered a C# private assembly with two versions (using regasm),
so that the registry contains entries like this:

...\InprocServer32\1.0.0.0 <= I want this
...\InprocServer32\1.0.2819.34866 <= unfortunate mistake

This was before I fixed the assembly version to 1.0.0.0. Now I'm trying to
create COM objects from C++, but COM reports Class not registered. It is
the 1.0.2819.34866 entry that messes things up. If I remove this entry (it
should not be there, really) everything works fine. Unfortunately, while
this is easy for me to do, for my clients it is not.

Is there a way I can force my application to load a specific version? I am
not using the GAC, but COM.

I have created a geo.exe.config like this:

?xml version ="1.0"?
configuration
startup
supportedRuntime version="v1.1.4322" /
/startup
runtime
assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"
dependentAssembly
assemblyIdentity name="Roadrunner"
version="1.0.0.0"
publicKeyToken="baaf840ae384ab38"
culture="neutral" /
/dependentAssembly
/assemblyBinding
/runtime
/configuration

This hasn't helped though. Any help is much appreciated!

Thanks in advance!
