Worked on the JetBrains/resharper-unity repository to enhance language detection accuracy within the Unity ReSharper YAML plugin. Addressed a bug where .cshtml files were misclassified as Blazor and ensured .razor files were correctly recognized as Blazor, even in the absence of assembly references. Improved the underlying logic by basing language calculation on actual project file types, which increased accuracy for Unity project language inference. Updated and stabilized unit tests to better reflect real-world project scenarios, reducing flaky results in continuous integration. Utilized C#, ASP.NET, and Blazor, with a focus on plugin development and robust unit testing practices throughout the process.
