[WPF series] basic learning-WPF design patterns overview, wpf-wpf
Introduction

The "Design Pattern" is something cool for programmers to pick up, And it truly makes programer of the beginner Design Pattern intoxicated. Too many experiences tell us that "everything must be done in an appropriate way and we must learn to stop it. The same is true for the "design mode". It is not intended for the "Mode" (except for the beginner demo ), then the original intention of the design model proposed by GOF and other elders is lost (the basis for reusable object-oriented software ).

Layer-3 architecture in common applications

 

MVC> MVP> MVVM

 

The following figure shows the design mode of the presentation layer:

MVVM mode relationship

 

   
The View is bound to the ViewModel, and some commands are executed to request an action from it. In turn, ViewModel communicates with the Model, and ViewModel tells the Model to update to respond to the UI.
    
In this way, the UI design for the application is relatively independent, and it is very easy to replace the uidesign ("whatever you want" to design your interface ). At the same time, when the UI and functions become increasingly loosely coupled, the functional testability is getting stronger and stronger.
 

 

Common open-source MVVM frameworks

 

Based on the structure separated by the front-end XAML of WPF and the back-end code, MVVM is the best design mode favored by WPF applications. There are also many MVVM mode frameworks:

Microsofts MVVM Toolkit	No updates now. If you are interested, please refer to the source code.
MVVM Foundation	No updates now MVVM initial implementation
MVVM Light Toolkit	Looking at the name, we can see that it is a lightweight MVVM framework, and now there are many applications on mobile clients.
Https://github.com/Caliburn-Micro Https://caliburn.codeplex.com/	The framework is relatively large, but there is also a lite version, and the main tool is the lite version.
Patterns & practices: Prism	Microsoft's open source code is continuously updated, The advantage of Microsoft is inherent.

Further research will be conducted on how to choose these frameworks.

Currently, the author only chooses Prism for development, and other frameworks will be gradually used.

The younger brother recently wanted to learn WPF and had a certain C # Foundation. He recommended a textbook, deep dive into wpf, and did not know how,

<Wpf advanced programming> if you have C # basics, I think it is quite suitable for you. I just bought one.

What is the basis for learning WPF technology? How to get started?

This ...... What else do you worry about when there are so many slave servers? Action is taken.
From the perspective of non-professionals:
For strong people like you, wpf seems to be nothing more than the XAML language, but it is essentially Xml.
As for the separation of the interface and code --ASP.net, isn't that true?
The rest is to select a textbook. I personally have read two books: WPF secrets (thin points, it seems easier to grasp the global) and WPF programming book (thick points, it seems easier to understand ).
