A basic sample to learn about WPF.
Dependency is what happens when one class changes to another class. Dependency injection loosely couples objects by injecting dependencies from outside rather than creating the objects directly.
- Increased extensibility
- When you add new features or modules, dependency injection allows you to inject new objects to increase scalability.
- Reduced dependencies
- Reduced dependencies mean that modifications to an object are less likely to affect other objects, reducing the number of modification points.
- Increased reusability
- Injected classes are naturally modularized, improving reusability.
- Ease of unit testing
- Dependency injection facilitates unit testing because it is easy to replace the dependent part with a mock object, etc.
- Unit tests can be separated by object
- Nuget
- App.xaml.cs
- Override the "OnStartUp" method
- Create a "ServiceCollection"
- Register a service in the "ServiceCollection"
- Run the "BuildServiceProvider" method of "ServiceCollection"
- Run the "GetService" method on the Provider
- Injecting Interface in the constructor
In the dictionary definition, it is generally referred to as a model or format for creating something. For example, in a word processor, a document template is a predefined format or layout used to create new documents. In WPF, templates are used to define the appearance and layout of user interface (UI) elements, and you use ControlTemplate or DataTemplate to define appearance and behavior templates.
- Definition
- A template used to define the layout and appearance of a UI control.
- Primarily used to customize or change the appearance and behavior of a control.
- Component
- Contains several UI elements (Panel, Border, TextBlock, etc.)
- Completely override the visual appearance and layout of the control
- Advantages
- Fully customizable appearance and behavior of the control
- Increases reusability
- Disadvantages
- Modifying the ControlTemplate also changes the behavior and layout of the control. There is a higher need to set up new behaviors and layouts
- This makes code difficult to read when constructing complex UIs
- Trigger
- Allows you to dynamically change the UI by directly accessing the Controls you define
- Definition
- Used to define how data-bound data will be represented
- Primarily used to specify the layout for each item in the ItemsControl
- Component
- Contains the UI elements to display the data Used as a template for each item in the ItemsControl (DataTemplateSelector)
- Advantages
- Overrides how data is displayed
- Templates can be created for various data types, making them easy to reuse
- Disadvantages
- You can't change the appearance or behavior of the control because you're only dealing with the visual representation of the data.
- Trigger
- Used to dynamically change the UI based on property values of data-bound items
- To change the UI of the parent control, define a RelativceSource and use it.
- Arrange
- Set up all the prerequisites for the test. In this step, you create the target object to test, set the required input values, and configure the test environment. test environment.
- Act
- Call the object or method under test and perform the behavior you want to verify in your test code. This is where the actual execution of the test takes place.
- Assert
- Validate the results of your test and verify that the expected results match the actual results. This step determines whether the test succeeded or failed.
- Dependency Injection
- Isolate your code by injecting objects that depend on the code being tested.
- You can isolate your code for easier control in your tests and inject mock objects in the mock
- Extendability and flexibility of code
- Interfaces make your code more extensible
- Changing the behavior of a test case without modifying its code You can change the behavior of a test case without modifying its code
- Publishing
- Publishers or topics generate events or messages and deliver them to subscribers.
- Publishers create events and notify subscribers about them.
- Publishers typically publish events for specific topics, and whenever an event occurs, it is broadcasted to all subscribers of that topic.
- Subscribing
- Subscribers receive events generated by publishers and process them.
- Subscribers subscribe to specific topics and receive events related to those topics for processing.
- Each subscriber registers to subscribe to a publisher and defines the processing logic for the events they receive.
- features
- Loose Coupling
- Publishers and subscribers are not directly connected; they communicate through an intermediary. This increases the flexibility and scalability of the system.
- Scalability
- New publishers or subscribers can be added or removed, and the system can scale by distributing the load.
- Event-driven
- Various components of the system react to events asynchronously, allowing for more efficient processing.
