In our project we have a Sitecore 9.0.1 solution conforming to Helix architecture. We also have Sitecore Commerce installed.
When I add a reference to Sitecore.Commerce.Core to a project in the Helix structure, it requires Microsoft.Extensions.DependencyInjection 2.0.0, while Sitecore 9 uses 1.1.1. They are not compatible and after deployment there is a bunch of errors.
How to use Sitecore.Commerce.Core with the Helix project?
