Documentation: Customer Details Interfaces

1. Purpose

This module defines two marker interfaces, ICustomerDetailsView and ICustomerDetailsViewModel, which establish the contract for the Customer Details feature within an MVVM (Model-View-ViewModel) architecture. These interfaces extend base view and view model abstractions (IBaseView and IBaseViewModel respectively), enabling type-safe identification and binding of customer-specific UI components without defining additional members. They serve as extension points for the customer details functionality within the broader DTS.Common.Interface namespace.

---

2. Public Interface

ICustomerDetailsView

Namespace: DTS.Common.Interface
Inheritance: IBaseView

public interface ICustomerDetailsView : IBaseView { }

A marker interface representing the View component for customer details. Declares no members; all behavior is inherited from IBaseView. Used to identify and type-check customer details view implementations.

---

ICustomerDetailsViewModel

Namespace: DTS.Common.Interface
Inheritance: IBaseViewModel

public interface ICustomerDetailsViewModel : IBaseViewModel { }

A marker interface representing the ViewModel component for customer details. Declares no members; all behavior is inherited from IBaseViewModel. Used to identify and type-check customer details view model implementations.

---

3. Invariants

• Inheritance Contract: Both interfaces must always inherit from their respective base types (IBaseView and IBaseViewModel). Any implementation must satisfy the contracts defined by those base interfaces.
• Naming Convention: The interfaces follow a naming pattern aligned with MVVM conventions (I[Feature]View and I[Feature]ViewModel).
• Empty Interface Constraint: Neither interface defines additional members; they rely entirely on their base interfaces for functionality. This design implies they serve as type markers rather than behavioral contracts.

---

4. Dependencies

This module depends on:

• DTS.Common.Base — Provides IBaseView and IBaseViewModel base interfaces from which these interfaces inherit.

What depends on this module:

Cannot be determined from source alone. Potential consumers would include:

• Concrete implementations of ICustomerDetailsView (e.g., WinForms, WPF, or web-based views)
• Concrete implementations of ICustomerDetailsViewModel
• Any factory or dependency injection registration code that resolves customer details components

---

5. Gotchas

• Empty Interfaces: Both ICustomerDetailsView and ICustomerDetailsViewModel define no members of their own. Developers implementing these interfaces must consult IBaseView and IBaseViewModel to understand the actual contract requirements. The purpose of these empty interfaces is unclear from source alone—they may serve as marker interfaces for DI registration, navigation systems, or feature identification.
• Base Interface Contracts Unknown: The actual members, properties, and methods that implementations must provide are defined in IBaseView and IBaseViewModel, which are not included in the provided source. The complete contract cannot be documented without those files.
• Feature Scope Ambiguity: The source does not indicate what specific customer details data or operations this feature encompasses. The scope of "Customer Details" (e.g., read-only display, editing, validation) cannot be determined from these interfaces alone.
