- TTargetType
The target navigation source type.
- TDerivedType
The derived structural type.
Parameters
- navigationExpression
- Expression<Func<TDerivedType,TTargetType>>
A lambda expression representing the navigation property for the relationship.
For example, in C# t => t.MyProperty and in Visual Basic .NET Function(t) t.MyProperty.
- targetEntitySet
- String
The target navigation source (entity set) name for the binding.
Returns
A configuration object NavigationPropertyBindingConfiguration that can be used to further configure the relationship further.
