1. Lab 1: Basics

In this lab you will apply the basics of C# and develop an Avalonia app using the simple code behind approach.

1.1 Preparation

You need to come to this lab well-prepared, i.e. read and understand everything the basics and XAML. Do the exercises.

  • Install Rider and .Net, see IDE.
  • Clone the gitlab repository. An invitation will come per email 2 days before your lab.
  • Create a simple application based on the template Avalonia .NET App that uses simple code behind and
    • has a button to add random numbers to a list
    • shows the sum of all numbers of the list
    • has a ComboBox with different filtering criteria for your list resulting in LINQ queries
    • adds a random number asynchronously to the list

1.2 During the lab

In a random team of four students you will develop a small application using git and events, LINQ, extension methods and other C# language features within an Avalonia UI using code behind (no MVVM). I will specify the application at the start of the lab, i.e. you may not prepare the specific app.

  • I present the application to be build, and you ask questions to clarify the requirements (10 min).
  • Make yourself familiar with the infrastructure, i.e. everyone must be able to use the bis team screen (10 min).
  • Create the initial project together, use the template Avalonia .NET App (10 min).
  • Plan your first sprint (10 min).
  • Start pair programming (35 min).
  • Merge your code (15 min).
  • Sprint Review with all teams (10 min).
  • Short retrospective, how can you work better in the next sprint (15 min)?
  • Short break (15 min).
  • Plan your second sprint (10 min).
  • The other one is now using the keyboard and hence needs to pull the project first. Start pair programming (35 min).
  • Merge your code (10 min).
  • Sprint Review with all teams (10 min).
