We're trying to move our designers over to 64 bit workstations to deal with larger assemblies. Our PDM application uses the EModelView control quite extensively. So far, I am unable to find a means of referencing the 32 bit component within a .NET application operating in 64 bit mode (ie without using the "x86" cpu target, which breaks the application for 64 bit interoperation). Has anyone had any success with this? I'd appreciate any tips I can get.
