SOLID coaching

The aim of this repository is to provide a coaching material about SOLID.

Though this examples should be used from «students» itself, they are tailor-made to an agile technical mentoring approach.

About this repo

The repo is made using C# language on dotnet 6+.

The main branch intentionally contains a dirty code, that is not respecting any of the SOLID principles.

The steps/* branches contains the refactored code, each step has the explanation and an example of a SOLID principle.

Steps are subsequent: step 2 starts from step 1 and so on.

Example

• steps/01_SRP contains the code refactored to fulfill the Single Responsibility Principle
• steps/02_OCP contains the steps/01 code, but with the Open-Closed Principle implemented
• ...
• last step contains the fully refactored code, respecting all SOLID principles

Remarks

As the steps are sequential, an edit to the previous branch should be merged to the next step:
