Background To best understand Blazor-State, you should be familiar with Blazor, MediatR, the Command Pattern, and the Chain of Responsibility Pattern. Blazor Blazor is a framework that allows programmers to write client-side code in C#. Blazor provides near-native performance and requires no plugins, because it runs on top of WebAssembly. You can learn more about Blazor here. MediatR MediatR is an…

Typical Builder In the typical Builder Pattern, the Builder class has a number of methods which return itself, then a method which returns an instance of the class being built: To get a with certain properties, you would call: If you're unfamiliar with the Builder Pattern and/or want a more in-depth explanation, you can read my previous post on the Builder Pattern. Static Builder with Extension…

Reflection? What's that? Reflection is a tool in C# that can be used to access the metadata of a class. It has a number of uses, but it should generally be used as a last resort, as there are some drawbacks. Using reflection can lead to some performance limitations. More importantly, reflection - as you'll see below - allows you to access properties marked as private, protected, internal, etc…

I was working on a project recently where I needed exactly this functionality. Towards that end, I created a wrapper class. There are other ways I could have done this (and if you have other ideas on how to implement this, let me know in the chat below!), but as I'm comfortable with using Lists I decided to take the following approach: My has a , which can be added to using the public method…

This year, the event was virtual, so I was able to watch some amazing speakers from the comfort of my home, which was very nice. And, you, too, can watch amazing speakers from the comfort of your home, since the entire event is available on Stir Trek's YouTube. If that's not your thing, below are my notes on the sessions. They're mostly for my own reference later, but I thought others might find…

And in truth, downloading a csv is not all that complex at all. But since the internet gave conflicting advice, and it took me almost two hours to figure it out, here's what worked for me. Code Below, I'll summarize the necessary code to make this work. If you prefer, this code is available in this GitHub repo. .cshtml.cs Code-Behind My goal was to have a page download a .csv at the push of a…

What is integer division? In integer division, the remainder is discarded. For example, while "normal," or floating-point division of 1 / 4 results in 0.25, integer division of that same expression results in zero. Likewise, 26 / 5 will result in 5 in integer division, but 5.2 in floating-point division. What are the rules of integer division... In C#? In C#, the operator will result in an…

Rolling back the database is very easy, much easier than I'd feared when I originally realized I needed to do this. To help out you and my future self, here's how: Simply add the full name of the migration you want to roll back to after "update" in your database update script, which (if you're using the command line) will end up looking like this: The project I'm working with had multiple…

Last weekend, I played around with putting ends on some network cables, in preparation for fixing one in my house (which runs through the walls, so I'll only have a few chances to get that one right before I run out of cable). I used a kit with a specialized tool, though most, if not all, of the steps can be completed with common household tools; the only specialized tool necessary is a crimping…

Rather than using a JavaScript framework like Angular or React to write the UI portion of the code, programmers can use Blazor to write the client-side code in C#. How it works Blazor runs on top of WebAssembly, which is a low-level language designed to allow languages like C# to be run alongside JavaScript on the web without requiring a plugin. Essentially, the .NET DLLs making up your…
