Pre-bootcamp Learner Introduction
This section is designed to teach you the basic of C# programming. You should be able to follow it even if you’ve done little or no programming before. The goal is to get to the point where you can attend the Bootcamp training course, and start to understand and write real code.
If you do have some prior programming experience, read on – there are some bits you can skip over, but don’t move too fast as there could be something you’re not so familiar with that’s worth revising!
The objective of this section is to be able to understand and use the following C# programming concepts:
- Variables and assignment
- Conditional logic - the if statement
- Looping logic - the for, foreach and while statements
- Arrays
- Creating and calling methods and classes
- Building a simple console application
These topics will be addressed by way of Microsoft-provided tutorials.
You’ll also learn the very basics of the Git version control system, and how to put the code you’ve written on GitHub.
Setup
Development tools
Before beginning this preparation you will need a development machine with the following already installed – this information has been provided to your employer as technical prerequisites.
- .NET SDK (version 6.0.115)
- Visual Studio Code (VSCode) – this is the Integrated Development Environment for which the exercise content was written, and the following VSCode extensions should be installed.
Note that the course assumes that you will be using Visual Studio Code as your IDE, which is a more lightweight set of tools than the full Visual Studio package.
Git setup
Before beginning Bootcamp, you will need to be able to upload your exercise solutions to GitHub so that your trainer can see them. To do this, you’ll need the following.
If you do not already have a GitHub account, go to GitHub and “Sign Up” for one (it’s free). It’s fine to use an existing account if you have one.
If you have never used Git before, follow GitHub’s short tutorial just to get used to the basics. You can skip over “pull requests” for now if you wish – you won’t need them until you start collaborating with other team members.
Then create a Personal Access Token (PAT) on GitHub by following this tutorial. Choose “classic” rather than “fine-grained”. Name your token something like “C sharp training”, give it an expiry time of at least 6 weeks and ensure it has the repo scope. Make sure to copy the token because you’ll need it to connect to GitHub in a moment.
To check that your Git installation is working properly, create a folder in which you’ll store the code you’ll write for this course (e.g., C:\Work\Training
). Then in your Git client run a version of the following command:
git clone https://git@github.com:YourName/YourProject.git
You’ll need to replace YourName
by your GitHub account name, and YourProject
by the name of one of your GitHub repositories (you should have at least one if you’ve followed the tutorial on GitHub). The easiest way to get a url for the git clone
command is to navigate to your project in GitHub and find the green “Code” button. Click this and you should get a “Clone with HTTPS” box containing the correct URL to copy and use.
Once you run the git clone command above, you should be prompted for your GitHub login details. Instead of your password, use the PAT you created earlier.
You should find that your project is now downloaded locally into a new folder inside C:/Work/Training
. We’ll explore more about how to work with Git as we progress through the course.
If you have any trouble getting the above to work, get in touch with your trainer who should be able to give you some pointers to get moving.
Pre-bootcamp content structure
This pre-bootcamp section is built from the C# Fundamentals for Absolute Beginners video series on Microsoft Virtual Academy. Note that the number and order of the videos on the Microsoft site is different from what is linked here; we suggest that you rely on the links in this section rather than clicking on the ‘Next’ video.
As you go through the standard tutorials, you’ll be guided through a series of exercises to build a simple application with the tools that have been presented.
By the end of this section you should have all the basics you need to start writing your own C# code. But don’t panic if it doesn’t all make sense – help is on hand if you get stuck, and once you’ve learnt the basic syntax then during Bootcamp we’ll demystify any remaining puzzles and take your programming to the next level.
If you do already have prior experience you’re welcome to skim over any of the reading material that you’re already confident in. But make sure you’re proud of the code you’re writing, and if you’re not completely confident then re-read the material even if it’s largely familiar.
Further reading
There are two books that we recommend as C# learning resources. They’re not essential, but we’d recommend that all employers have at least the second of these on hand for reference as you continue your C# journey. Which book is best for your first foray into C# depends on your preferred learning style.
Head First C# (Stellman & Greene). This is a very practical hands-on introduction to C#, which explains everything from the basics to fairly complex concepts. It adopts a very informal, graphical style. The premise of the book is very much to throw you in at the deep end – the first chapter involves copying out the code for a computer game, most or all of which you won’t initially understand, but it uses this to explain the first concepts while still giving you an exciting and fully featured application to play with. As you progress through the book the same pattern continues, but you’ll understand increasingly large chunks of the code, until you reach the point where you understand everything!
Learning C# 3.0 (Liberty & MacDonald). This introductory book is more traditionally structured. It introduces topics one by one, using simple examples that focus only on the concepts you’ve already learnt. As a reference book for C# learners this is more suitable than Head First C#, because it’s easier to find a sub-section concentrating on some specific topic you want to look up. But some people find it a bit dry, and you might not want to read it cover-to-cover. Note that version 3.0 of C# is now a bit dated, but very little of the content is actually wrong – you’re just missing out on some of the newer features (and we’ll cover these separately where necessary). Sadly there’s not yet a more recent edition of this series – hopefully they’ll produce one soon!
Both books support the “Look Inside” feature on Amazon.co.uk, so if your employer doesn’t already have a copy lying about you can use that to get a feel for the content and then try to persuade them to buy you a copy of the best one! As mentioned above, we recommend that employers with C# learners have a copy of Learning C# 3.0, although there are other books they might point you to as alternatives.
Both books include various quizzes and exercises to complete. The answers are all in the books so you can test yourself. They’re worth doing – the only way to learn to program is to practice!
