Hello Kenan,
>>I want to make ForeignKey IsId and  musteriId areas but I did not succeed;
With your provided model, I made a test with and reproduced this issue and this issue is caused by a cause cycles or multiple cascade paths, the exception message also mentions and it actually provided the workaround which Specify ON DELETE NO ACTION or
ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. In the OnModelCreating method of your context class, adding code as below:
modelBuilder.Entity<PaymentBase>().HasRequired(p => p.CustomerBase).WithMany().WillCascadeOnDelete(false);
modelBuilder.Entity<PaymentBase>().HasRequired(p => p.OwnerShipBase).WithMany().WillCascadeOnDelete(false);
modelBuilder.Entity<DocumentBase>().HasRequired(p => p.CustomerBase).WithMany().WillCascadeOnDelete(false);
modelBuilder.Entity<DocumentBase>().HasRequired(p => p.OwnerShipBase).WithMany().WillCascadeOnDelete(false);
On my side, the model generates the database successfully.
Regards.
