It covers the 240 release, where 21 of 27 community pull requests were merged. [Watch on YouTube](https://www.youtube.com/watch?v=tjHDcjwsOIE) · Microsoft Dynamics 365 Business Central (YouTube) · 2024-04-04 · 20:20 · tier official · reviewed (checked by Opus) ## Overview The session introduces the BC apps repository on GitHub, launched in November 2023. It hosts source code for Microsoft-developed apps such as the system application, business foundation, test runner and performance toolkit. For the 240 release, the community submitted 27 pull requests and 21 were merged. The video then walks through the contribution flow: creating an issue from a template, getting an approved label, forking, developing in a Docker-based environment and opening a pull request. It shows the automated checks, the three-flavor build, the testing phase, and how to debug compile and test failures in GitHub using AL-Go output. ## Key points - The repository only hosts Microsoft-developed apps (system application, business foundation, some developer tools). It is not the place to report product defects with customer impact. - Contribution starts with a GitHub issue using one of two templates, implement a BC idea or fix a bug. Work begins after the issue gets an approved label. - A pull request needs resolved comments, at least two approvals from Microsoft engineers who maintain the repository, a linked approved issue, and passing build checks. Link an issue by writing # and the issue ID. - The pull request build compiles apps in three flavors: vanilla, with translations, and clean mode. Clean mode uses preprocessor directives such as 'clean 23', and it can fail while the vanilla build succeeds. - The second build phase runs tests on the system application and business foundation in vanilla and clean modes. All tests must pass. - AL-Go for GitHub runs the builds and tests. It gives a test summary and stack traces, and GitHub reports compilation errors inline in the pull request. - Automated pull requests update the BC artifact version, app baselines version and translation package version. They carry an automation tag and need no action from contributors. ## Chapters - [0:00](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=0s) Introduction and session overview - [1:39](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=99s) BC apps repository launch and statistics - [3:00](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=180s) Repository structure and features - [4:21](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=261s) Automation processes in BC apps - [5:16](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=316s) Contribution process: from idea to approval - [7:17](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=437s) Setting up development environment and creating pull requests - [8:31](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=511s) Pull request requirements and merge criteria - [11:10](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=670s) Pull request build phases and testing - [13:11](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=791s) Debugging and test failure analysis - [16:35](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=995s) Contribution checklist and getting help - [17:50](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=1070s) Key takeaways on open-source development - [19:11](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=1151s) Resources and next steps ## Features | Feature | Status | At | |---|---|---| | BC apps GitHub repository | status not stated | [1:39](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=99s) | | Community contribution to BC 240 | status not stated | [1:39](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=99s) | | AL-Go for GitHub automation | status not stated | [2:39](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=159s) | | BC artifact version automation | status not stated | [4:21](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=261s) | | App baselines version automation | status not stated | [4:56](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=296s) | | Translation package version automation | status not stated | [4:56](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=296s) | | GitHub issue templates for contributions | status not stated, demoed | [6:17](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=377s) | | Pull request approval workflow | status not stated, demoed | [6:57](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=417s) | | Docker-based development environment setup | status not stated | [7:18](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=438s) | | Linked work items check for pull requests | status not stated, demoed | [10:12](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=612s) | | Microsoft internal work items tracking | status not stated, demoed | [10:49](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=649s) | | Pull request build with three compilation modes | status not stated, demoed | [11:10](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=670s) | | Preprocessor directives for clean builds | status not stated, demoed | [12:11](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=731s) | | Pull request testing phase | status not stated, demoed | [12:31](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=751s) | | GitHub PR debugging with file changes view | status not stated, demoed | [13:51](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=831s) | | GitHub test failure summary and stack trace | status not stated, demoed | [15:21](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=921s) | | BC apps repository contribution process | status not stated | [16:35](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=995s) | | GitHub contribution help and support | status not stated | [17:16](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=1036s) | | Bug reporting in the contribution process | status not stated | [17:50](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=1070s) | | Equal contribution requirements for internal and external developers | status not stated | [18:51](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=1131s) | | Business Foundation application on GitHub | status not stated | [19:31](https://www.youtube.com/watch?v=tjHDcjwsOIE&t=1171s) | ## AL objects mentioned As heard in the captions.
