.NET is a cross-platform runtime for cloud, mobile, desktop, and IoT apps.
Role in this project:Back-end Developer
Back-end DeveloperContributions:143 reviews, 82 commits, 143 PRs in 3 years 6 months
Contributions summary:Nathan contributed to the .NET runtime project by implementing an imprecise version of the `GetTotalAllocatedBytes` method within the Mono runtime. This involved modifying several files related to garbage collection, including `icall-def.h`, `sgen-alloc.c`, `sgen-mono.c`, and related header files, suggesting a focus on memory management and garbage collection optimization. Further commits involved integrating and testing the implemented functionality, alongside modifications to related sample projects.
