C# Design Patterns

csharp-design-patterns

A bunch of demo codes for:

1. GoF Design patterns written in C#
2. Unit testing with Xunit
3. Mocking with Moq
4. Using FluentAssertions.
5. Ninject is used for testing the demo on DI based singletons.

How To Run the Demos

1. Demos are divided into folders with the pattern.
2. To build all, enter dotnet build
3. To execute all the tests, enter dotnet test or dotnet test -l:"console;verbosity=detailed" to be more verbose.

TODOs

1. Interpreter Pattern
2. Unit of Work
3. Repository Pattern
4. CQRS with MediatR

Adding a Pattern

1. Under Patterns folder, create a new directory with the new pattern name. Example: mkdir RepositoryPattern
2. Change directory to new folder.
3. Create a new project. Example: dotnet new classlib -n RepositoryPattern -o . or just dotnet new webapi if you like having the same project name as the current folder.

Adding a package

1. Change directory to the pattern you want to add a package for or to the test folder (if you want to add a test package).
2. Add the package: Example: dotnet add package FluentAssertions
