The main goal of this project is implementing and better understanding DDD and hexagonal architecture principles. \n# Also known as\n* Ports and Adapters\n* Clean Architecture\n* Onion Architecture\n# Hexagonal architecture\n![hexagonal](/hexagonal.png?raw=true \"hexagonal\")\n\n\n\nWith hexagonal architecture\n* Domain layer contains enterprise wide logic and types and does not depend anything except these \n* Application layer contains business logic and types\n* Infrastructure layer (including persistence, messaging, logging, presentation) contains all external concerns\n* Presentation and Infrastructure layers depend only on Application\n* Infrastructure dependencies can be replaced\nwith minimal effort. For instance, we can switch data store without touching business code. \n\n## Getting Started\nUse these instructions to get the project up and running.\n\n### Prerequisites\nYou will need the following tools:\n\n* [Visual Studio Code or 2019](https://www.visualstudio.com/downloads/) or [JetBrains Rider](https://www.jetbrains.com/rider/download)\n* [.NET Core SDK 3.0](https://www.microsoft.com/net/download/dotnet-core/3.0)\n\n### Setup\nFollow these steps to get your development environment set up:\n\n 1. Clone the repository\n 2. At the root directory, restore dependencies\n ```\n dotnet restore\n ```\n 3. Build the solution\n ```\n dotnet build\n ```\n 5. Run tests\n ```\n dotnet test\n\t ```\n## Technologies\n* .NET Core 3.0\n* ASP.NET Core 3.0\n## License\nThis project is licensed under the MIT License - see the
