Allow specifying different column names per table in TPT, TPC or entity splitting #19811
Description
E.g. int Id could be mapped to int Id in People and to string CustomerId in Customers
TPC:
modelBuilder.Entity<Person>().ToTable("People")
.InheritPropertyMapping(false);
modelBuilder.Entity<Customer>().ToTable("Customers", t =>
{
t.Property(c => c.Id).HasColumnName("CustomerId");
});Entity splitting:
modelBuilder.Entity<Customer>(cb =>
{
cb.ToTable("Customers");
cb.SplitToTable("CustomerDetails", t =>
{
t.Property(c => c.Id).HasColumnName("CustomerId");
})
};Also allow to map a base property to the derived table in TPT
TPT:
modelBuilder.Entity<Person>().ToTable("People");
modelBuilder.Entity<Customer>().ToTable("Customers", t =>
{
t.Property(c => c.Id).HasColumnName("CustomerId");
