Everything You Wanted to Know About Multiline Strings

Working with strings is probably one of the earliest things we get to do as C# developers. In fact, if you consider that most of us start with the "Hello, World!" example, you're being exposed to the string type right away. But as you continue to use strings, you'll quickly find that you want to work with strings that span multiple lines and how we define multiline strings might be a tricky topic for beginners. No sweat! In this article, we'll look at some simple code examples that demonstrate how to define multiline strings. I'll also link over to GitHub where you can see this code committed and pushed up to a public repository. Finally, the last example contains a special bonus that I think you'll like (even if it's a slightly more advanced topic). Read until the end! The…

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…

Tasks, BackgroundWorkers, and Threads – Simple Comparisons for Concurrency

(This article is intended to be a spiritual successor to this previous entry, and now includes Tasks!) Even if you're new to C#, you've probably come across at least one of Tasks, Threads, or BackgroundWorkers. With a bit of additional time, it's likely you've seen all three in your journey. They're all ways to run concurrent code in C# and each has its own set of pros and cons. In this article, we will explore how each one operates at a high level. It's worth noting that in most modern .NET applications and libraries you'll see things converging to Tasks. The Approach I've gone ahead and created a test application that you can find here. Because this is in source control, it's possible/likely that it will diverge from what we see in this article, so I just wanted to offer…

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…

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…

Downtime? Time to Build!

The COVID-19 pandemic has caused many of us to stay isolated and at home, but that's OK! I genuinely enjoy developing software and wanted to take this opportunity to focus on learning. Having some downtime has afforded me to try putting together a system that I otherwise might not have explored building. In this article, I'll share different aspects about an application I'm building that purposefully put me outside of my comfort zone. In my opinion, having downtime is an opportunity to learn and grow! It's time to take advantage of that. When the app and system is ready to showcase I'll share more insight into what's actually being built! The Client Framework The application being built was intended to run on multiple mobile platforms, so Xamarin was my choice here. I have briefly used Xamarin several years ago, but…

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…
