ASP.NET Identity deep dive - Part 3 (Authentication)

September 14, 2024  6 minute read  

This article is one of a number of articles I will write over the coming month and will go into depth about the ASP.NET Identity system. My outline thus far: Project setup Account registration Signing in and out with a username and password Password reset Email confirmations Social logins Today, I’m tackling authentication - that is, signing in and out of an account using the web UI. You may remember from my last article that I set up the initial web UI to include a link to ...

ASP.NET Identity deep dive - Part 2 (Registration)

September 13, 2024  13 minute read  

This article is one of a number of articles I will write over the coming month and will go into depth about the ASP.NET Identity system. My outline thus far: Project setup Account registration Signing in and out with a username and password Password reset Email confirmations Social logins As you may remember from the last article, the first user journey I am going to implement is the registration journey. This is actually one of the more complex journeys with several parts t...

ASP.NET Identity deep dive - Part 1 (Project setup)

September 11, 2024  8 minute read  

You may have noticed that I included ASP.NET Identity in a project a couple of posts ago. I’m currently doing a deep dive into ASP.NET Identity with an eye towards an OIDC identity service based on OpenIddict. Identity is a complex topic and I still recommend that developers integrate another service rather than write their own: Keycloak is a good option if you have to store your own data, Auth0 is a good option when you just want a bunch of social providers, Corbado has support for...

.NET Aspire configuration patterns

September 09, 2024  10 minute read  

If you recall my last article, I transitioned my working application to .NET Aspire. This opinionated pattern allows me to run a complete microservice application within Docker Desktop, but then seamlessly deploy to Azure Container Apps and other platform services with the same code base. This is a great productivity boost for a developer. My current project builds an OIDC identity service that has both username/password (local) authentication and social logins like Google and Facebook. To ...

Local development for the cloud: Transitioning to .NET Aspire

September 05, 2024  13 minute read  

I’ve been working on a new project recently. It requires that I work with microservices and containers as it will eventually be runnable on either Kubernetes or (more likely) Azure Container Apps. My latest task is to get ASP.NET Identity working with PostgreSQL. In order to properly debug the code, I need the ASP.NET bits to be running locally. But to integrate with PostgreSQL, I need to set up containers and docker compose. This all feels like “too much work”. Wouldn’t it be amazing if...

Making ASP.NET Core applications readable - the options patterns

September 03, 2024  6 minute read  

Applications are read more often than they are written. The normal situation when a developer comes onto a project is that anything from a couple of weeks to several months is requried to come “up to speed” on the code base. Making the efforts required for readability of the code is important, and I spend a ton of time up front to ensure my applications are understandable without needing an in-depth lesson from me on how it works. Let’s take an application I am starting (today actually). I...

Centrally managing dependencies in your C# solutions

August 15, 2024  3 minute read  

Today, I’d like to talk about the best way to centrally manage dependencies in your dotNET solutions. It’s common for a single solution to comprise multiple projects. The happy path for maintaining dependencies in Visual Studio involves right-clicking on the project and selecting “Manage NuGet packages…”. Once you have a set of packages, you can keep them in sync by right-clicking on the solution and doing the same thing. By using “Manage NuGet packages” for the solution, you can update m...

Better data validation exceptions with C#

August 10, 2024  6 minute read  

There are times when I look at code I have written and think to myself “there has to be a better way.” When I start thinking like this, I start by looking at the documentation - the .NET official documentation is incredibly well written and simple to digest, and the fundamentals section is something I believe every language documentation should aspire to. Take exceptions, for example. When I started my career in software development, methods were written with a block of validations at the ...

Building Bootstrap apps from SASS with ASP.NET Core

August 08, 2024  6 minute read  

I’m building a new web application with ASP.NET Core, and I’m using Visual Studio Code with the C# Dev Kit so that I can really dive deep into the benefits and problems of using VS Code as a Visual Studio replacement. A frontend project is a good one to start with since I can check out the ways that the solution is presented while still having all the goodness of the VS Code development experience for JavaScript and TypeScript. As part of the application, I wanted to build a lean Bootstrap C...

Organizing service injection in ASP.NET Core Minimal APIs

August 07, 2024  4 minute read  

For the longest time, the Controller was the only way to introduce an API into your application. With the latest versions of ASP.NET Core, Minimal APIs became available. These offered the potential to write less code and be more efficient since they didn’t carry the baggage of the controller with them. That does come with some drawbacks, however. For me, one of the main ones is that it is so much easier to write unreadable code. WIth some basic practices, however, you can use minimal APIs ...
