The Dofactory Design Pattern Framework 4.5 is a product of Dofactory, a company that provides training and consulting services for software developers. The Dofactory Design Pattern Framework 4.5 is a collection of resources that help you learn and implement design patterns in C#. It includes the following components:
Gang of Four: This is a set of 23 classic design patterns that were first described by four authors in their book Design Patterns: Elements of Reusable Object-Oriented Software. These patterns are categorized into three groups: creational, structural, and behavioral. The Dofactory Design Pattern Framework 4.5 provides a PDF document that explains each pattern with diagrams and code examples. It also provides a Visual Studio solution that contains the source code for each pattern.
Head First: This is a set of 12 design patterns that were popularized by the book Head First Design Patterns by Eric Freeman and Elisabeth Robson. These patterns are more practical and easy to understand than the Gang of Four patterns. The Dofactory Design Pattern Framework 4.5 provides a PDF document that explains each pattern with diagrams and code examples. It also provides a Visual Studio solution that contains the source code for each pattern.
Patterns in Action: This is a reference application that demonstrates how to use design patterns in a real-world scenario. The application is a web-based order management system that uses ASP.NET MVC, Entity Framework, WCF, and jQuery. The Dofactory Design Pattern Framework 4.5 provides a PDF document that describes the architecture and design of the application. It also provides a Visual Studio solution that contains the source code for the application.
Spark: This is a rapid application development tool that helps you create web applications using design patterns. The tool generates code based on your specifications and preferences. The Dofactory Design Pattern Framework 4.5 provides a PDF document that explains how to use Spark. It also provides an executable file that launches Spark.
Plan: This is a project management tool that helps you plan and track your software projects using design patterns. The tool helps you define your requirements, tasks, milestones, and deliverables. The Dofactory Design Pattern Framework 4.5 provides a PDF document that explains how to use Plan. It also provides an executable file that launches Plan.
Visio UML Diagrams: This is a collection of UML diagrams that illustrate the structure and behavior of the design patterns and the reference application. The diagrams are created using Microsoft Visio and can be edited or printed as needed. The Dofactory Design Pattern Framework 4.5 provides a folder that contains the Visio files for the diagrams.

How to Use the Dofactory Design Pattern Framework 4.5?
Once you have downloaded and unzipped the Dofactory Design Pattern Framework 4.5, you can start exploring and learning from the various components. Depending on your level of experience and interest, you can choose different options to learn about design patterns and how to apply them in C#.
Exploring Design Patterns
If you are new to design patterns or want to refresh your knowledge, you can start by reading the PDF documents that explain each pattern with diagrams and code examples. You can also open the Visual Studio solutions that contain the source code for each pattern and run them on your computer. You can choose between two options to explore design patterns:
Option A: Gang of Four: This option covers the 23 classic design patterns that are widely used and recognized by software developers. These patterns are more abstract and theoretical than the Head First patterns, but they provide a solid foundation for understanding the principles and benefits of design patterns. You can find the PDF document and the Visual Studio solution for this option in the Gang of Four subfolder.
Option B: Head First: This option covers 12 design patterns that are more practical and easy to understand than the Gang of Four patterns. These patterns are based on real-world scenarios and problems that you may encounter in your software projects. They also use more modern and idiomatic C# code than the Gang of Four patterns. You can find the PDF document and the Visual Studio solution for this option in the Head First subfolder.
In addition to the PDF documents and the Visual Studio solutions, you can also view the UML diagrams that illustrate the structure and behavior of each pattern. The UML diagrams are created using Microsoft Visio and can be edited or printed as needed. You can find the Visio files for the diagrams in the Visio UML Diagrams subfolder.
Applying Design Patterns
If you want to see how design patterns are used in a real-world application, you can explore the Patterns in Action component. This is a reference application that demonstrates how to use design patterns in a web-based order management system that uses ASP.NET MVC, Entity Framework, WCF, and jQuery. The application follows a layered architecture and uses various design patterns to achieve separation of concerns, loose coupling, high cohesion, testability, and maintainability. You can learn how to apply design patterns by following these steps:
Step 1: Functionality: Before diving into the code, you should first understand what the application does and how it works from a user's perspective. You can run the application on your computer by opening the Visual Studio solution in the Patterns In Action subfolder and pressing F5. You can then browse through the web pages and try out different features such as logging in, viewing products, placing orders, checking out, etc.
Step 2: Solution: After getting familiar with the functionality of the application, you should take a look at how it is organized and structured in Visual Studio. You can see that the solution contains several projects that represent different layers of the architecture: UI (user interface), Service (business logic), Data (data access), Model (domain entities), CrossCutting (common utilities), Test (unit tests), etc. You can also see that each project has a reference to one or more other projects or external libraries.
Step 3: Layers: Next, you should understand how each layer of the architecture works and interacts with other layers. You can read the PDF document that describes the architecture and design of the application in detail. You can find this document in the Patterns In Action subfolder. The document explains each layer's purpose, responsibilities, components, dependencies, interfaces, etc. It also shows how data flows from one layer to another using diagrams.
Step 4: Patterns: Finally, you should identify which design patterns are used in each layer and how they help achieve better software quality. You can read the PDF document that explains each pattern with diagrams and code examples. You can find this document in the Gang of Four subfolder. The document covers 15 design patterns that are used in different layers of the application: Abstract Factory, Builder, Factory Method, Prototype, Singleton, Adapter, Bridge, Composite, Decorator, Facade, Proxy, Chain of Responsibility, Command, Observer, and Strategy.
Using Spark and Plan
In addition to exploring and applying design patterns, you can also use the Dofactory Design Pattern Framework 4.5 to create your own web applications using design patterns. The framework provides two tools that help you with this task: Spark and Plan.
Spark: This is a rapid application development tool that helps you create web applications using design patterns. The tool generates code based on your specifications and preferences. You can choose the type of application (ASP.NET Web Forms or MVC), the database (SQL Server or Oracle), the data access technology (ADO.NET or Entity Framework), the design patterns (Abstract Factory, Factory Method, etc.), and the user interface (Bootstrap or jQuery UI). You can also customize the appearance and behavior of your application using various options and settings. You can launch Spark by running the executable file in the Spark subfolder. You can also read the PDF document that explains how to use Spark in detail. You can find this document in the Spark subfolder.
Plan: This is a project management tool that helps you plan and track your software projects using design patterns. The tool helps you define your requirements, tasks, milestones, and deliverables. It also helps you estimate the time and cost of your project based on the complexity and size of your application. You can also monitor your progress and performance using various charts and reports. You can launch Plan by running the executable file in the Plan subfolder. You can also read the PDF document that explains how to use Plan in detail. You can find this document in the Plan subfolder.
