With this:
var mapper = new ModelMapper();
mapper.Class<Activity>(c =>
{
c.DiscriminatorValue(0);
c.Discriminator(map =>
{
map.Column("DISCRIMINATOR_TYPE");
map.NotNullable(true);
map.Column(colMap => colMap.Index("IDXActivityEntityType"));
});
c.Id(x => x.Id, map => map.Generator(Generators.Guid));
c.Property(x => x.Title);
});
mapper.Subclass<FormActivity>(c =>
{
c.DiscriminatorValue((int)ActivityType.Form);
});
The mapping is
<class name="Activity" discriminator-value="0">
<id name="Id" type="Guid">
<generator class="guid" />
</id>
<discriminator type="Int32">
<column name="DISCRIMINATOR_TYPE" not-null="true"
index="IDXActivityEntityType" />
</discriminator>
<property name="Title" />
</class>
<subclass name="FormActivity" discriminator-value="1" extends="Activity" />
