- navigationExpression
- Expression<Func<TRelatedEntity,TEntity>>
A lambda expression representing the reference navigation property on the other end of this
relationship (post => post.Blog). If no property is specified, the relationship will be
configured without a navigation property on the other end of the relationship.
Returns
An object to further configure the relationship.
Remarks
Note that calling this method with no parameters will explicitly configure this side of the relationship to use no navigation property, even if such a property exists on the entity type. If the navigation property is to be used, then it must be specified.
