Hello All,

I am calling a c# assembly registered with codebase switch from my VB6
application everything runs perfect. I have compiled same assembly in
the separate folder but upon accessing this assembly by instantiating
one of the class I get the following error

Run Time Error 80131040 (FUSION_E_REF_DEF_MISMATCH)

Please note that a Guid attribute has been defined in AssemblyInfo.cs
of the assembly. So both versions of assemblies have same Guids. I
unregister binary from the first folder (regasm /u) and register the
developer version of binary and got the error mentioned above.

I tried to run fusion log program but its not showing me anything.

Any help in this regard will be appreciated.

Regards,
Usman
