  You submit your code for review and the CI/CD pipeline for your branch fails. I wish I could have known about it before I submitted the PR!

• 2025-04-12 Use JSON Property Names in ASP.NET Validation Error Messages

  ASP.NET Web API projects using controllers have a powerful validation mechanism that provides callers with detailed messages when they have sent invalid payloads. One of the problems though, is that the messages don’t use JSON Property Names if the model properties are decorated with [JsonPropertyName] attributes. Let’s fix that.

  In Part 1 of Customizing OpenAPI Documentation In ASP.NET, we looked at how to ensure responses for each the status code were provided and that the payloads. There are still more customizations we can make.

• 2025-03-16 Customizing OpenAPI Documentation In ASP.NET - Part 1

  The default OpenAPI documentation generated from your ASP.NET code is rarely correct. Or rather, it is rarely what you want it to be. Let’s see how we can make it better.

• 2025-03-15 Configuring OpenAPI In ASP.NET

  Providing documentation to callers of an API can be extremely beneficial. It can mean the difference between an easy onboarding experience or frustration and a lot of trial and error.

• 2025-03-09 Returning ProblemDetails In ASP.NET

  Continuing my research from last week Using ProblemDetails in ASP.NET, I want to include ProblemDetails in other scenarios. For example, when a user receives a 401 or 403 response, there is no payload included in the response. I would prefer to include a ProblemDetails payload, making it simpler for callers to use the API.

• 2025-03-02 Using ProblemDetails In ASP.NET

  I wrote about using ProblemDetails a while back:

  Problem Details with ASP.NET Core

  Since then, they have become a first-class citizen in the ASP.NET libraries and can be added as follows:

  Broken Object Level Authorization is a huge security problem. Let’s explore the options available to us in an ASP.NET application

• 2025-02-16 Scripting SQL Server Users

  Do you know what permissions a user has in SQL Server? Generating scripts to create users and grant permissions can save you a lot of trial and error.

  I often advocate (some would say preach) that progress should be made in small batches. Let’s find some data to back up that claim.

  Here are the guidelines I try to follow when I make changes to a code base.

  Installing tools on Windows can sometimes be challenging. The .NET CLI has a great way to distribute tools to your team.

• 2025-01-12 Using Central Package Management with .NET

  It is often the case that a solution with a large number of projects share a lot of the same NuGet packages. Central Package Management is a means to help keep the package versions synchronized across the projects.

• 2025-01-11 Helpful Git Commands

  I recently was trying to figure out which files I had modified with my feature branch in git. It wasn’t as easy as I thought. I decided to document some of the git commands I frequently use (so I don’t have to keep searching fo them again and again)

• 2025-01-04 Generating Code Coverage Reports .NET

  Code coverage can be a highly debatable topic, but I find it very helpful in knowing which classes are under represented in my suite of unit tests. I’ve relied on the UI versions of test runners to provide this data. Let’s explore what we can do with the command line.
