The Art and Science of Software Development

Authentication and Identity

In this entry, we’ll start to add in more structural elements, namely the authentication components of the UI and Identity Model classes in our Web API. Fortunately, ASP.NET Core and Visual Studio do a lot of this work for us via scaffolding tools. Our main concern is to take this auto-generated code, modify it where needed, and move it into the appropriate layers of our Clean Architecture solution, namely the Infrastructure and Presentation layers.

Architectural Template

This is an architectural template for building web applications which is based upon my interpretation of the Clean DDD and CQRS concepts that I introduced in the previous entry. To demonstrate this, I've created a demo application which attempts to solve a fictional problem for a fake organization. In developing this template, I studied solutions and tutorials from a handful of experts.

Domain Driven Design

What is Domain-Driven Design? It is a software design methodology which seeks to efficiently create business logic components and functionality from business requirements, typically by working closely with domain experts. In this entry, I give a brief overview of Domain-Driven Design (DDD) and discuss its importance in modern software development.

Software Architecture

This is the first in a series of blog entries in which I will elaborate on progressively more advanced subjects, beginning with fundamental software patterns, practices, principles and conventions; culminating in the establishment of an architectural template demonstrating how to build enterprise business applications which can be deployed to the Microsoft Azure cloud. Along with this and future blog entries, I'll be using a demo application for a fictional organization to demonstrate the concepts I discuss. Additionally, I talk about some topics that are relevant to the "inner game" of software development.

If Visual Studio is your samurai sword, then the C# programming language along with patterns and practices of structured software development are your fighting techniques, principles and disciplines. In this post, I'm going to talk about some of the features of C#, versions 6, 7, and 8. I've chosen to focus on these three versions because not only are they the most recent (obviously) but also because the style of language version releases started to change with version 6, focusing on a more frequent tempo and more granular features. Even more importantly, the syntax and feel of the language itself seemed to turn a corner with C# 6, marking what in my opinion is an evolving paradigm shift toward functional programming.
