There would have to be an additional nhlinq function to accomplish
this & at current, there isn't. A super easy workaround is to just
map the discriminator as a readonly property and select that property
directly.
cm.Property(x => x.DiscrimType, x => {
x.Column("DiscriminatorType");
x.Insert(false);
x.Update(false);
});
