The change introduces language-specific type elements for XAML parts and modifies CreateTypeElement to accept an IPsiModule parameter, improving processing and representation of F# code-behind files in ReSharper.

May 2025 monthly summary for JetBrains/resharper-unity focusing on build stability and cache optimization. Implemented a critical fix to resolve a compilation error by adjusting the cache-wait behavior (waitOnlyPrimaryCaches: true in WaitForCaches), reducing CI failures and preserving existing functionality. The change is low-risk with no new features, delivering immediate business value through more reliable tooling for Unity development.

January 2025 monthly summary for JetBrains/resharper-fsharp focused on stabilization and correctness in F# tooling. No new features delivered this month. Major bug fix: resolved a FSharpRequest compilation error by renaming property from BaseExpressionTypes to EligibleExtensionArgumentTypes, implemented in commit 38bde3f6461a57e62b549705eb11a49ca1fd3e31. This change clarifies the intent of request typing, reduces compile-time failures, and improves downstream tooling reliability. Technologies/skills demonstrated include debugging, code maintenance, and Git-based change management within a C#/F# tooling context. Business value includes shorter debugging cycles, more reliable builds, and stronger IDE support for F# projects.

Month 2024-11 — Delivered Unity Language Level Detection Improvements for ReSharper in JetBrains/resharper-unity. Refactored the language level detection pipeline, added caching for project language level data, and enhanced logic to determine the latest supported language level by considering Unity installation paths and Roslyn compiler versions, providing more accurate recommendations for Unity developers and reducing misconfigurations.
