Márton, our genius software architect, shared his story of contributing to the ASP.NET Core repository. In this blog post, he recounted the challenges faced while working on a project involving an API and two React applications. Debugging efforts led him to discover issues with hosting the applications in a subdirectory, prompting him to explore the code and identify a solution.
During development, Márton noticed that the admin application failed to load properly due to a problem with the proxy code. After thorough debugging, he realized that the Map middleware in ASP.NET Core did not include the prefix provided in the first parameter. Additionally, the concatenation of URI segments differed from the expected behavior with strings. He found an existing GitHub issue but decided to propose his own solution to address the problem.
Márton’s initial attempt at submitting a code change incited integration test failures, which were unrelated to his modifications. After resolving the test issues by merging the latest main branch, he received approval and awaited inclusion in the main branch release with .NET 7.0. Surprisingly, another issue emerged, mirroring the previous problem with the same line of code. Driven by determination, Márton embarked on resolving both issues simultaneously.
During the process, Márton collaborated with code owners who provided feedback and requested assistance with manual testing. To facilitate testing and future maintenance, he took the initiative to write unit tests for the code. Despite the complexity of testing an extension method for the HttpContext class, Márton succeeded in verifying the correctness of the URL using an HTTP client with a mocked HTTP message handler.
With his tests passing and necessary adjustments made, Márton’s code was eventually merged into the main branch. His conclusion and takeaway emphasize the importance of a cautious mindset when contributing to open-source projects, especially those as complex as ASP.NET Core. The significance of semantic versioning, automated tests, and meticulous code reviews is highlighted in his blog post as essential elements for maintaining robust libraries.
