Microservices with MassTransit Syllabus

Create a microservice-architected restaurant application.

We will have an inventory API with one service per ingredient. Each ingredient will support a method of both modifying (consumer) and retrieving (producer) inventory.

Creating & “cooking” an order will also be supported, with each ingredient-service also responsible for preparing the ingredient.
