Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

public class InlineDataTest
{
    [Theory]
    [InlineData(1, 1)]
    [InlineData(2, 2)]
    [InlineData(5, 5)]
    public void Should_be_equal(int value1, int value2)
    {
        Assert.Equal(value1, value2);
    }
}

Following is what you need for this book:

This design patterns book is for beginners as well as intermediate-level software and web developers with some knowledge of .NET who want to write flexible, maintainable, and robust code for building scalable web applications. Knowledge of C# programming and an understanding of web concepts like HTTP is necessary.

With the following software and hardware list you can run all code files present in the book (Chapter 1-18).

Introduction

This repository contains the code of An Atypical ASP.NET Core 6 Design Patterns Guide. It also contains pointers to help you find your way around the repository. This repo is also there to rectify any mistake that could have been made in the book and missed during reviews.

Please open an issue if you find something missing from the instructions below or the book's instructions.

UML Diagrams

In the book, we have UML Class diagrams, UML Sequence Diagrams, and some non-UML diagrams. We assumed that most-developers would know about UML, so we decided not to add pages about it.

The author used diagrams.net (draw.io) to draw the diagrams (which is free and open-source).

The following two articles should help you get started if you don't know UML:

Getting Started

You need a copy of An Atypical ASP.NET Core 6 Design Patterns Guide to make sense of the code projects as many projects start with bad code and get refactored into better ones.
- You can find An Atypical ASP.NET Core 6 Design Patterns Guide on Amazon.com
You need an IDE/Text Editor like Visual Studio or Visual Studio Code, but you could do without (not recommended).
- Download Visual Studio
- Download Visual Studio Code
You need .NET 6 SDK. If you installed Visual Studio, you should be fine. Otherwise, here is the link:
- Download .NET 6

With that in place, you should be good to go!

Build and Test

All projects and solutions can be built using the .NET CLI or Visual Studio. You can find the most useful commands in the introduction chapter, under Running and building your program or online.

The two commands that you will need are:

dotnet build to build a project or solution
dotnet test to run a test project or all tests of all test projects of a solution.

Content/Code

Throughout the book, there are many projects, and many are copies with a little update done to them, so they may look a lot alike. Here, we will build a list that maps harder to find code to its file or directory in the Git repository. If you find something missing, erroneous, or hard to find, please open an issue and let us know.

Contribute

Please open an issue if you find some missing docs, errors in the source code, or a divergence between the book and the source code.

For more information, check out the Code of conduct.
