Worked on the FirelyTeam/firely-net-sdk repository to restore C# collection initializer support for the Parameters class, which had been lost during the SDK 6 migration. Addressed this by implementing the IEnumerable<ParameterComponent> interface, enabling developers to use familiar object initializer syntax and improving overall developer ergonomics. Added two unit tests to verify both collection initializer construction and direct enumeration, ensuring future compatibility and regression safety. This work focused on SDK development and unit testing in C#, directly addressing a migration-related break and increasing test coverage to maintain compatibility and reduce friction for teams upgrading to the latest SDK version.
