Simple Secrets for Access to the dotnet Record Type

In C# 9.0 we received access to a great quality of life type called the record. You can read more about that from Microsoft here. Record types allowed us as dotnet programmers to skip a lot of boiler plate code, thereby saving us time and making code more readable. Wins all around! Before record types, we might have simple data transfer objects (called DTOs) that would look something like the following: pupublic sealed class MyData { public MyData( string value1, int value2) { Value1 = value1; Value2 = value2; } publc string Value1 { get; } publc int Value2 { get; } } And for a simple class with two properties... I think we can all agree that the verbosity here is just over the top. With the record type that we were given access to, we can now write…

async void – How to Tame the Asynchronous Nightmare

You're an intermediate dotnet programmer and you mostly know your way around using Tasks. You sprinkle async and await through your code, and everything is working just as expected. You've heard time and time again that you always want the return types of your asynchronous methods to be a Task (or Task<T>) and that async void is essentially the root of all evil. No sweat. One day you go to wire up an event handler using the syntax myObject.SomeEvent += SomeEventHandler, and your event handler needs to await some asynchronous code. You take all of the right steps and change your method signature to get that beautiful async Task added in, replacing void. But suddenly you get a compile error about your event handler not being compatible. You feel trapped. You're scared. And then you do the unspeakable... You change…

Simple Data Types in C#: A Beginner’s Guide

As a C# developer, understanding the different simple data types in C# and when to use them is crucial for writing efficient and maintainable code. I've been trying to spend more time this year putting together some content aimed at really introductory level programming. There's plenty of resources available online, but I want to do my part to ensure I can help break down some of the barriers for people getting started on their programming journey. In this beginner's guide, we will look at the basics of the most commonly used simple data types in C#, including int, float, double, byte, char, bool, and string. We will also look at how these data types differ from each other and when to use them in your C# programming! Integer Data Types The most commonly used integer data types in C# are…

Pythonnet – A Simple Union of .NET Core and Python You’ll Love

Python is a powerful and versatile programming language that has become increasingly popular. For many, it's one of the very first programming languages they pick up when getting started. Some of the highest traffic posts on my blog many years after they were written look at using C# and Python together. Today we're going to explore how you can use Python from inside a C# .NET Core application with much more modern approaches than my original articles. Enter Pythonnet! Pythonnet Package & Getting Started We're going to be looking at Python for .NET in order to accomplish this goal. This library allows you to take advantage of Python installed on the running machine from within your .NET Core applications. You must configure it to point at the corresponding Python DLL that you'd like to use, and after a couple of…

The Hottest New Open Source OpenAI API for C#

If you have an internet connection then you have probably heard of ChatGPT from OpenAI by now. Odds are you might have even given it a whirl to see what it's all about. Personally, I know that I was quite skeptical at first but I've been blown away at how well it's able to converse about topics I ask it. I've even asked it to generate various scenarios for me and it will conclude by explaining why the different facets it chose were good choices. Incredible stuff. I'll be using this to help chip away at content for my role playing game. When it comes to using OpenAI effectively, I have a great deal to learn. It's all very new to me, especially with respect to how to structure prompts and get the most out of the interactions with such…

TileMap – How To Get ALL The Tiles Effortlessly!

If you're building a 2D game in Unity3D, odds are you've come across the TileMap component. The TileMap is a powerful tool that allows you to create a grid of tiles that you can render your tiles with instead of hand-placing individual game objects with sprites. It has a host of built in functionality that you might otherwise find yourself manually writing, like mapping coordinates to particular cells on a map. And what's even cooler about using a TileMap? You don't need to handroll your own editor to paint tiles! I think I'd pass on having to do that. But have you found yourself in a situation where you want to get all of the painted tiles on a TileMap? You may have found it's not quite as obvious as you'd have hoped! What We Have To Work With On…

Xamarin Forms – Jumpstart Your App With Autofac

I love dependency injection frameworks ever since I started using them. Specifically, I'm obsessed with using Autofac and I have a hard time developing applications unless I can use a solid DI framework like Autofac! I've recently been working with Xamarin and found that I wanted to use dependency injection, but some of the framework doesn't support this well out of the box. I' was adamant to get something going though, so I wanted to show you my way to make this work. Disclaimer: In its current state, this is certainly a bit of a hack. I'll explain why I've taken this approach though! In your Android projects for Xamarin, any class that inherits from Activity is responsible for being created by the framework. This means where we'd usually have the luxury of passing in dependencies via a constructor and…

xUnit Tests Not Running With .NET Standard

Having worked with C# for quite some time now writing desktop applications, I've begun making the transition over to .NET standard. In my professional working experience, it was a much slower transition because of product requirements and time, but in my own personal development there's no reason why I couldn't get started with it. And call me crazy, but I enjoy writing coded tests for the things I make. My favourite testing framework for my C# development is xUnit, and naturally as I started writing some new code with .NET Standard I wanted to make sure I could get my tests to run. Here's an example of some C# code I wrote for my unit tests of a simple LRU cache class I was playing around with: [ExcludeFromCodeCoverage] public sealed class LruCachetests { [Fact] public void Constructor_CapacityTooSmall_ThrowsArgumentException() { Assert.Throws<ArgumentException>(() =>…

RPG Development Progress Pulse – Entry 2

Progress Pulse - Entry 2 Things have been pretty busy in real life the past couple of weeks, so I haven't had too much time for working on this. However, for this entry in the progress pulse series I'll talk about some of the challenges I had while looking at making a generic data (de)serialization API + implementation, and why I chose to make some of the decisions I did! Which Tech To Pick? I've felt burned in the past by trying to do data serialization for my game framework because it's always created a barrier for refactoring once it's in place (i.e. i change some data i need and now i have to re-make or migrate allllll my SQL data). So I was thinking about how I plan to store game state, which I have written about, and then…

Autofac Modules and Code Organization

What are Autofac Modules? I've been writing a little bit about Autofac and why it's rad, but today I want to talk about Autofac modules. In my previous post on this, I talk about one of drawbacks to the constructor dependency pattern is that at some point in your application, generally in the entry point, you get allllll of this spaghetti code that is the setup for your code base. Essentially, we've balanced having nice clean testable classes with having a really messy spot in the code. But it's only ONE spot and the rest of your code is nice. So it's a decent trade off. But we can do better than that, can't we? Autofac modules! We can use Autofac modules to organize some of the code that we have in our entry point into logical groupings. So an…
