Updated `SqlDatabaseVectorSearch.csproj` to include Dapper package reference, version `2.1.35`.
Updated Program.cs to include dimensions parameter for AddAzureOpenAITextEmbeddingGeneration sourced from aiSettings.Embedding.Dimensions. Reformatted SQL command texts in VectorSearchService.cs for better readability. Introduced EmbeddingServiceSettings class in AzureOpenAISettings.cs to allow optional dimensions configuration. Updated appsettings.json to include new Dimensions property under Embedding section.
The custom stylesheet injection for Swagger UI has been removed.
Specific width constraints for checkbox inputs in the Swagger UI
have been removed from the CSS.

Updated Swagger documentation title and endpoint description in Program.cs to reflect a shift towards general SQL Database usage instead of specific SQL Server implementation. Simplified the document upload endpoint by removing the `LinkGenerator` parameter and enhancing clarity in operation descriptions, emphasizing support for uploading documents to SQL databases for indexing and question answering purposes.
Refactored code to centralize configuration access through a single `AppSettings` instance in `ChatService` and `VectorSearchService`, improving maintainability and reducing verbosity. Introduced new configuration settings (`MaxTokensPerLine`, `MaxTokensPerParagraph`, `OverlapTokens`, `MaxChunksCount`) in `AppSettings.cs` and `appsettings.json` for enhanced flexibility in content processing. Adjusted existing settings usage (`MessageLimit`, `MessageExpiration`) to align with the new access method, and removed obsolete settings (`StoragePath`, `VectorDbPath`, `QueuePath`). These changes simplify the codebase, make the application more configurable and adaptable to different content characteristics, and allow for more controlled vector search operations.
- Updated README.md with details on Vector Support in Azure SQL Database, application functionalities, and setup instructions.
- Removed inheritance of `Question` class from `Search` class and deleted `Search` class.
- Minor adjustment in Program.cs for endpoint description consistency.
- Simplified appsettings.Development.json by removing the empty "ConnectionStrings" section.
- Enhanced Script.sql with SQL commands to create `DocumentChunks` and `Documents` tables, including schema for identifiers, content, embeddings, document names, creation dates, and established a foreign key relationship between the two tables.
- Converted `Question.cs` and `Search.cs` records to `record class` syntax for clarity.
- Organized API endpoints with tags and added new GET and DELETE endpoints in `Program.cs`, including OpenAPI documentation improvements.
- Removed commented-out code in `Program.cs` for cleaner codebase.
- Introduced `WithTags` for better API operation categorization in Swagger UI.
- Added a TODO comment in `ChatService.cs` for future improvement on chunk length check.
- Clarified `using` directives in `VectorSearchService.cs` with namespace aliasing to improve readability.
- Refactored document deletion in `VectorSearchService.cs` to use a private helper method and expanded service capabilities with a new `GetDocumentsAsync` method.
