Worked on reliability and resource-management improvements for storage sessions in the NServiceBus.Persistence.Sql and NServiceBus repositories. Addressed a race condition in StorageSession.Dispose by introducing IAsyncDisposable and ensuring proper disposal of transaction and connection objects, which enhanced concurrent message handling. Improved disposal robustness by updating tests for repeated disposal and suppressing finalization in derived classes, promoting more predictable resource lifecycles. Focused on backend development and concurrency control using C# and object-oriented programming, with additional attention to integration and unit testing. These changes reduced disposal-related errors and improved maintainability, particularly under high-load scenarios involving synchronized storage sessions and saga persistence.
