After installing SDL Web Experience Optimization 8 on Web 8.5, when I open business process type I am getting below error..

Method not found: 'Tridion.ContentManager.CoreService.Client.ISessionAwareCoreService Tridion.Web.CMUtils.CMSession.get_CoreServiceClient()'. Do you want to close this window?

Error Details:

Am I missing something..!!!

It sounds like you installed the previous version of Experience Optimization on top of 8.5 (especially considering this other question you asked). However, XO is just a feature in the suite installer now. You don't install it separately.

You'll need to uninstall the old one and modify your SDL Web 8.5 installation to include Experience Optimization.
