.NET 7 Has Arrived
.NET 7 is out, and it is a pretty significant upgrade. Performance, ASP.NET, MAUI, and C# 11 are some of the new features. Microsoft continues to improve the performance improvements of .NET. As I have discussed in a previous blog post, Microsoft has needed to improve the cold start performance of .NET for a while….

What Type of Mistake
I am not good at drawing; I wish I were, but I am not. I got a lot of practice when my kids were younger. We spent a lot of time drawing with chalk on our driveway and sidewalks. We often drew things my kids were into at the time: cars, families, and trains. For…

.NET Cold Starts
I love .NET and C#, and I think it is the best platform for writing software in many ways. C# was created to make it easier to write quality business software. And it has evolved to be better and better. But there is one thing that still isn’t fixed with .NET: Cold starts. In software…

Earned Value
Tracking project progress isn’t as simple as you would think. Common questions often include, “are we there yet?”, “are we going to end over budget?”, and “are we going to end past the schedule?” These questions keep people up at night. And the answer, “we’ll be done when we are done,” usually doesn’t fly. Earned…

Pulling Calendar Items Using Swift
In a previous blog post, I took you through how to pull contacts from iOS or Mac. In this post, I will show you how to pull calendar items. This turns out to be very similar to pulling contacts. First, we must request access to the calendar. As part of requesting access, we must create…

With that said, let’s learn to swim. What is CORS? From Mozilla: “Cross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows…

Twilio Verify
The Twilio Verify API allows us to verify users while not requiring them to enter (or remember) a password. This is a huge benefit for many systems. Having fewer passwords is better. Twilio Verify is extremely easy to set up. First, you must have a Twilio account. This is pretty straightforward. Once you have an…

Top to (More) Bottom with Angular and .NET Core
Our previous activities got us an Angular application making an HTTP call to a .NET Core backend to retrieve a shopping list. In this activity, we will extend our .NET backend to use SQL Server. First, let’s create a Shopping database. Next, we need to create a ShoppingListItems table. Now that we have a database…

SQL Server Single-User Mode
Sometimes you can’t get into SQL Server. Maybe you forgot a password, or something got misconfigured. You are locked out. What to do when this happens? My go-to is putting SQL Server in Single-User Mode. Doing this is pretty straightforward. First, open a command shell in administrator mode. Then stop the SQL Server Service. net…

Designing for On-Prem
We all build everything for the cloud, right? Sometimes we get very focused on a small world, often believing that all software is some cloud-focused startup. But that isn’t accurate. Much of software development isn’t geared toward the cloud; it is geared to on-premises hosting (on-prem for short). Probably one of the big differences between…
