Rebus in .NET - Service Bus Implementation

When working with distributed applications that need to asynchronously communicate with each other, the “Publish-Subscribe” pattern is very common. To avoid being tightly coupled to a message broker, such as RabbitMQ, we use an abstraction layer, known as a service bus. Rebus is one such service bus implementation for .NET that allows us to easily communicate asynchronously between services. This article makes use of Docker to run our message broker (RabbitMQ) server locally.

Schedule Jobs with Quartz.NET

Recurring, background tasks are widespread and very common when building applications. These tasks can be long-running or repetitive and we don’t want to run them in the foreground, as they could affect the user’s experience of the application. So instead we must schedule these jobs to run in the background somewhere. To achieve this in .NET, we can use the Quartz.NET library to manage the creation and scheduling of these jobs. This article makes use of Docker to run SQL Server server locally. Optionally a local install of SQL Server can be used.
