Month: 2025-03 Key highlights: - Startup Performance Optimization for Extension NGen and Build Simplification in dotnet/razor: Consolidated changes to improve startup performance and streamline build dependencies; tuned NgenPriority for project references to potentially improve startup time and memory usage; removed custom RazorNgendVSIXSourceItem in favor of directly including Microsoft.CodeAnalysis.Razor.Compiler.dll with Ngen enabled. Impact and business value: - Improved startup responsiveness for Razor tooling, contributing to faster IDE experiences and reduced memory footprint during extension load. - Simplified build and dependency management, lowering maintenance overhead and risk of future regressions. Major bugs fixed (through the optimization work): - Resolved stability concerns tied to Razor tooling startup by removing a bespoke RazorNgendVSIXSourceItem workaround and migrating to a direct DLL inclusion; stabilized NGen-related behavior. Technologies/skills demonstrated: - .NET, NGen, build optimization, dependency management, Roslyn/Razor.Compiler.dll usage, and practical consolidation of tooling artifacts. Overall impact and accomplishments: - Delivered a focused performance and maintenance improvement for the Razor extension, with measurable improvements expected in startup time and memory usage, and a cleaner build surface.
