Worked on enhancing the dotnet/efcore repository by implementing support for binding UInt128 values as TEXT in SQLite through the SqliteValueBinder. This feature focused on parameter binding, allowing large integer values to be stored in SQLite databases while maintaining compatibility with existing read operations, which continue to return strings. The approach included developing comprehensive provider-level unit tests to ensure correct binding behavior across a range of UInt128 values. Leveraging C# programming, database management, and unit testing skills, the work addressed a specific gap in EF Core’s SQLite integration, enabling more robust handling of large numeric data within .NET applications.
