This pull request introduces a significant update to the web-api.web project, transitioning the ToDo functionality to use Entity Framework Core with a SQL Server database. The changes include the addition of a database context, repository pattern implementation, migration files, and updates to the application configuration and endpoints.

Database Integration and Configuration:

• Added ToDoContext class to define the Entity Framework Core database context for managing ToDo entities. Includes entity configuration for properties such as Title, Description, and IsCompleted. (src/web-api.web/Data/ToDoContext.cs, src/web-api.web/Data/ToDoContext.csR1-R29)
• Introduced connection string for SQL Server in appsettings.json to enable database connectivity. (src/web-api.web/appsettings.json, src/web-api.web/appsettings.jsonR2-R4)
• Updated web-api.web.csproj to include necessary Entity Framework Core packages (Microsoft.EntityFrameworkCore.SqlServer and Microsoft.EntityFrameworkCore.Tools). (src/web-api.web/web-api.web.csproj, src/web-api.web/web-api.web.csprojR12-R16)

Repository Pattern Implementation:

• Added IToDoRepository interface defining CRUD operations for ToDo entities. (src/web-api.web/Repositories/IToDoRepository.cs, src/web-api.web/Repositories/IToDoRepository.csR1-R13)
• Implemented ToDoRepository class for database operations, including logging for debugging purposes. (src/web-api.web/Repositories/ToDoRepository.cs, src/web-api.web/Repositories/ToDoRepository.csR1-R78)

Migration and Database Schema:

• Created initial migration (InitialCreate) to define the schema for the ToDos table. Includes columns for Id, Title, Description, and IsCompleted. (src/web-api.web/Migrations/20250604210641_InitialCreate.cs, src/web-api.web/Migrations/20250604210641_InitialCreate.csR1-R36)
• Added ToDoContextModelSnapshot for tracking the current database model state. (src/web-api.web/Migrations/ToDoContextModelSnapshot.cs, src/web-api.web/Migrations/ToDoContextModelSnapshot.csR1-R50)

Service and Endpoint Updates:

• Refactored ToDoSvc to use IToDoRepository for database operations instead of in-memory storage. (src/web-api.web/Services/ToDoSvc.cs, src/web-api.web/Services/ToDoSvc.csR2-R60)
• Updated API endpoints in Program.cs to align with RESTful conventions (/todos instead of /todo) and ensure proper integration with the database-backed service. (src/web-api.web/Program.cs, src/web-api.web/Program.csL36-R86)

These changes collectively enhance the scalability and maintainability of the ToDo functionality by leveraging Entity Framework Core and adhering to best practices such as the repository pattern.

Add an explicit route constraint ({id:int}) to ensure the id parameter is parsed as an integer and avoid unintended route matches.

Suggested change

	app.MapGet("/todos/{id}", async (int id, ToDoSvc toDoSvc) =>
	app.MapGet("/todos/{id:int}", async (int id, ToDoSvc toDoSvc) =>

Consider using AsNoTracking() (e.g., _context.ToDos.AsNoTracking().ToListAsync()) for read-only queries to reduce change tracking overhead.

Suggested change

	var toDos = await _context.ToDos.ToListAsync();
	var toDos = await _context.ToDos.AsNoTracking().ToListAsync();

[Copilot]

For read-only fetch, consider using AsNoTracking() before the query (e.g., _context.ToDos.AsNoTracking().FirstOrDefaultAsync(...)).

Suggested change

	return await _context.ToDos.FirstOrDefaultAsync(t => t.Id == id);
	return await _context.ToDos.AsNoTracking().FirstOrDefaultAsync(t => t.Id == id);
