we are migrationg from 2013 sp1 to web 8.5 , however we are not able to fetch anything from tridion content delivery. we have added 8.5 dd4t provider dll and removed 2013 one, added new tridion prefixed dlls, removed ambient data reference in web.config, added discovery service to app settings. we have checked discovery service storage config and it seems correct and the page is also in the broker.
i can see the taxonomies are published , while going in to the discovery service logs it is not able to find reference of microsoft.data.edm assembly
Any suggestion would be helpful, thanks
