In order to support 32- and 64-bit versions of our application we load assemblies that are specific to 32- and 64-bit (including IEvolution assemblies) from x64/x86 subfolders. This worked fine with version 4.4.
After upgrading to version 5.0 it seams that iecore.dll assembly is not loaded from ievolution2.dll location (the subfolder in our case), but from the executing assembly folder. Since the dll is not located there, it gets loaded from windows\system... folder - so the wrong dll gets loaded.
How can we work around this problem without having all of the assemblies and executables in x64/x86 subfolders?
