I know that I can Map(x => x.GroupName).WithUniqueConstraint() for a single property.
Map(x => x.GroupName).WithUniqueConstraint()
But how do create a composite unique constraint in fluent nHibe
In the latest version that I have used, it isUniqueKey("KeyName")that does this.
UniqueKey("KeyName")
Map(x => x.Something).UniqueKey("KeyName"); Map(x => x.SomeOtherThing).UniqueKey("KeyName");
