How to validate models before SaveChanges in EntityFramework Core 2?

SaveChanges() from an EntityFramework context fails silently

Have you tried bringing it in as a new Business object? rather than first constructing one?... var fb = new Business(); //fb.Id exists and is an int but it is auto incr in the db fb.Name = ub.ACCOUNT_NAME; fb.ServiceManager = ub.SERVICE_MANAGER; fb.AccountManager = ub.ACCOUNT_MANAGER; fb.SalesPerson = ub.SALESPERSON; fb.Created = DateTime.Utc...

implement both EntityFramework 6 and EntityFramework Core side-by-side in a n-tier solution

Since ASP.NET Core projects weren't there when EF6 commands were developed, they don't know how to operate with them. These projects will probably need to be unloaded before using EF6 commands....Additionally, you may be able to clearly state...-StartupProject... EF6 project to get around the problem.
