Mapper.AssertConfigurationIsValid throws Mapper not initialized
Hi. I tried calling Mapper.AssertConfigurationIsValid on my project but it threw an exception. Aside from services.AddAutoMapper(typeof(Startup)) and a MappingProfile, what else am I missing? Thanks!

Exception details
System.InvalidOperationException
HResult=0x80131509
Message=Mapper not initialized. Call Initialize with appropriate configuration. If you are trying to use mapper instances through a container or otherwise, make sure you do not have any calls to the static Mapper.Map methods, and if you're using ProjectTo or UseAsDataSource extension methods, make sure you pass in the appropriate IConfigurationProvider instance.

The static API is going away - you need to resolve the mapper from the service collection.
