Avalonia Samples

Welcome to Avalonia.Samples. This is a collection of minimal samples, which should make it easy for everyone to get started with Avalonia. Each sample is focusing on only one aspect of Avalonia.

Or file a new bug-report or feature request in the Issues-section.

📂 Organization of the Samples

Every sample can be found in its own subfolder and can run without any reference to another sample. Nevertheless, we have a *.slnx-file which has all projects in one solution, if you are looking for a complete collection of samples.

ℹ️	We migrated to the newer *.slnx-File format, which should be supported from all major IDEs. If it doesn’t work for you, please use the project-files inside the subdirectories.

You can find the list of samples below. The samples are structured in different categories and difficulties. For better search results, each sample is also tagged with some buzz-words.

In every sample folder you will find a README-file, which describes the sample in detail and, if applicable, has links to further information and documentation.

🐣 Difficulties

Each sample is tagged with its difficulty. The degree of difficulty describes how much base-knowledge a user should have.

🔘	Difficulty	Degree of knowledge
🐣	Beginner	A Beginner must not have any knowledge of Avalonia. Nevertheless, some basic knowledge of C#, X(A)ML and your IDE is mandatory.
🐥	Easy	Some very basic knowledge of Avalonia is needed.
🐔	Normal	The user is somewhat experienced with Avalonia.
🐉	Hard	These samples are focusing on non-standard tasks, which most users will not need to know.

Issues and Feature Requests

If you file a new issue or feature request, please fill in the templates available. If you found an issue in an existing sample, please link the sample and, if possible, point us to what is wrong.

Pull Requests

ℹ️	Pull requests may be discussed and probably not every pull request will be merged in the end. If you are not sure, please 🗯 Get in touch with us first. Anyway, every contribution is welcome.

Fixing an existing sample

If you find that in an existing sample something is unclear or missing, you can update the sample and file a pull request. Spelling mistakes or wrong wording can also be changed in a pull request.

❗	If you change the difficulty or the buzz-words, remember to also update the main page.

Adding a new sample

1. Add a new Project to the Solution: src ► Avalonia.Samples ► Avalonia.Samples.sln

2. In the root directory of the new sample add a README-file. We highly suggest using a template which you can find here:

   1. AsciiDoc-Template: If you want to provide richer content, we suggest using the ascii-doc-template.

   2. Markdown-Template: If you prefer not to use AsciiDoc, you can instead use the Markdown-template.
