There are lots of ways to contribute to the Uno Platform, and we appreciate the help from the community. You can provide feedback, report bugs, give suggestions, contribute code, and participate in the platform discussions.

The Uno Platform is an ongoing effort, and as Microsoft progresses on UWP, the Uno platform follows the trails. While the development remained closed for a while, the areas covered by Uno may not suit everyone's needs, which is why your feedback is important to us.
We want to hear about your experience, scenarios, and requirements.
If you think you've found a bug, the first thing to do is search the existing issues to check if it's already been reported.
If not, please log a new bug report.
The best way to get your bug fixed is to be as detailed as you can be about the problem. Providing a minimal project with steps to reproduce the problem is ideal. Here are questions you can answer before you file a bug to make sure you're not missing any important information.
- Did you read the documentation?
- Did you include the snippet of the broken code in the issue?
- What are the EXACT steps to reproduce this problem?
- What specific version or build are you using?
- What operating system are you using?
- What platform(s) are you targeting?
GitHub supports Markdown, so when filing issues, be sure to check the formatting in the 'Preview' tab before hitting submit.
If you need a UWP feature or WinUI feature that Uno doesn't support yet, you should submit a feature request. Check existing issues first in case the same feature request already exists (in which case you can upvote the existing issue).
To help us understand and prioritize your idea, please provide as much detail about your scenario and why the feature or enhancement would be useful.
Wherever we possible we prefer to implement UWP/WinUI APIs for maximum cross-platform compatibility and existing code support, but for features/functionality not covered by UWP's API, the same feature request process applies.
If you have a question, be sure first to check out our documentation. But if you are still stuck, please visit GitHub Discussions where our engineering team and community will be able to help you.
If you've already done some Uno development, maybe there's a GitHub discussion question you can answer, giving another user the benefit of your experience.
For a more direct conversation, visit our Discord Channel #uno-platform.
The Uno Platform is an open-source project, and we welcome code and content contributions from the community.
Identifying the scale
If you would like to contribute to one of our repositories, first identify the scale of what you would like to contribute. If it is small (grammar/spelling or a bug fix) feel free to start working on a fix.
If you are submitting a feature or substantial code contribution, please discuss it with the team. You might also read these two blog posts on contributing code: Open Source Contribution Etiquette by Miguel de Icaza and Don't "Push" Your Pull Requests by Ilya Grigorik. Note that all code submissions will be rigorously reviewed and tested by the Uno Platform team. Only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.
Obtaining the source code
If you are an outside contributor, please fork the Uno Platform repository you would like to contribute to your account. See the GitHub documentation for forking a repo if you have any questions about this.
Submitting a pull request
If you don't know what a pull request is read this article: https://help.github.com/articles/using-pull-requests. Make sure the repository can build and all tests pass, as well as follow the current coding guidelines.
Pull requests should all be made to the master branch.
All commits must be in the Conventional Commits format. We use this to automatically generate release notes for new releases.

Summary of the changes (Less than 80 chars)

Tests
- Tests need to be provided for every bug/feature that is completed.
- Tests only need to be present for issues that need to be verified by QA (e.g., not tasks)
- If there is a scenario that is far too hard to test, there does not need to be a test for it.
- "Too hard" is determined by the team as a whole.
