This is the first post in the series were I’m actually getting into some code. You will be able to follow along the journey of creating a practical web application using Microsoft Orleans. This first post is really just setting the ground level to get familiar with the basics of Grains and Silos. By the end of this post I’ll have a simple demo app that is a functioning ASP.NET Core as our client/frontend with a Orleans Silo hosting our Grains.

I recently discovered through eventual consistency that my bounded contexts were not properly aligned with the business. I won’t lie, it took me quite a while to make this realization. This was most likely the case in many situations I’ve had in the past. Because of this realization, I wanted to let out some of my thoughts about eventual consistency and business alignment. Dependent Bounded Context I’ve often encounter situations where a bounded context requires information that another bounded context is responsible for. I’d like to use a simple example I’ve heard from Udi Dahan. In the context of an Ecommerce site. A… Read More »Eventual Consistency and Business Alignment
In my previous blog Query Objects instead of Repositories, I demonstrated creating query objects and handlers to encapsulate and execute query logic instead of polluting a repository with both read and write methods. Since we have moved away from repositories and are now using query objects, we will introduce the Mediator pattern. It will allows have a common interface that can be injected into our controller or various parts of our application. The mediator will delegate our query objects to the appropriate handler that will perform the query and return the results. First we will create an interface that will… Read More »Query Objects with a Mediator
