feature/c-sharp-12-primary-constructors #205
Conversation
WalkthroughThe changes refactor dependency handling and constructor usage across the API project. In the PlayerController and PlayerService classes, private fields are removed in favor of using constructor parameters directly, with corresponding updates to logging and caching operations. In the Repository class, the constructor is rewritten in primary constructor form, eliminating the separate DbContext field and initializing the DbSet directly from the passed parameter. These modifications simplify the code structure while retaining the original service call logic and behavior. Changes

151-152: Consider optimizing repository access for logging efficiency.In the logging statement, you're using string interpolation with the player object, which will serialize the entire object. For large objects, this could impact performance.
Consider using a more targeted approach if performance is a concern:
-logger.LogInformation("Simulating a random delay of {Milliseconds} milliseconds...", +logger.LogInformation("Simulating a random delay of {Milliseconds} milliseconds in {Method}", milliseconds + nameof(SimulateRepositoryDelayAsync) );

src/Dotnet.Samples.AspNetCore.WebApi/Services/PlayerService.cs (7)
8-13: Great use of C# 12 primary constructor.Your code now uses a C# 12 primary constructor to inject dependencies, eliminating the need for explicit private fields. This makes the code more concise while maintaining the same functionality.
15-23: Good refactoring of cache options.You've converted the previously method-based cache options into a static readonly field, which is more efficient since these options don't change at runtime. This approach avoids recreating the same options object for each cache operation.
25-42: Improved XML documentation.The documentation for static fields has been enhanced with better formatting and references to Microsoft documentation. This will make the code more maintainable and easier to understand for other developers.
50-55: Successfully refactored to use constructor parameters.Methods now directly use the injected dependencies from the primary constructor parameters rather than private fields. This simplifies the code without changing its behavior.
64-78: Successfully refactored cache access.The cache access code has been updated to use the constructor-injected
memoryCacheandloggerparameters directly, maintaining the same functionality with cleaner code.
87-87: Good use of static cache entry options.The code now uses the static
CacheEntryOptionsfield instead of creating new options for each cache entry, which is more efficient.
95-96: Consistently applied parameter-based dependency access.The repository and mapper access has been consistently updated throughout all retrieval methods to use the constructor parameters directly.
Also applies to: 101-102, 111-116, 130-134
src/Dotnet.Samples.AspNetCore.WebApi/Data/Repository.cs (3)
5-5: Excellent use of C# 12 primary constructor.The repository class now uses a primary constructor which simplifies the code while maintaining the same functionality. This is a good example of modern C# code.
8-8: Clean field initialization using constructor parameter.The
_dbSetfield is now initialized directly using thedbContextparameter from the primary constructor, which eliminates the need for a separate initialization in a constructor body.
13-13: Consistent use of constructor parameter.All instances of
_dbContexthave been replaced with thedbContextparameter from the primary constructor, maintaining consistent access to the dependency throughout the class.Also applies to: 23-23, 32-32
src/Dotnet.Samples.AspNetCore.WebApi/Controllers/PlayerController.cs (5)
12-16: Good adoption of C# 12 primary constructor.The controller now uses a primary constructor which eliminates the need for private fields for dependency injection. This makes the code more concise and follows modern C# practices.
44-44: Enhanced logging messages.The logging messages now include more specific context such as HTTP method and endpoint paths, which will make debugging and monitoring easier. The direct use of the injected
loggerparameter keeps the code clean.Also applies to: 50-53, 59-59

[warning] 34-44: CodeDuplication
This block of 10 lines is too similar to src/Dotnet.Samples.AspNetCore.WebApi/Controllers/PlayerController.cs:164
48-48: Direct service access using constructor parameter.The code now accesses the player service directly via the constructor parameter instead of a private field. This simplifies the code while maintaining the same functionality.
Also applies to: 57-57, 81-81
109-109: Improved multi-line logging format.The multi-line logging statements are now better formatted, making the code more readable while providing the same information to the logs.
Also applies to: 133-137
176-183: Consistently updated service access patterns.The PUT and DELETE operations consistently use the constructor-injected parameters, completing the refactoring approach across all controller methods.
Also applies to: 201-209
