fix: use IHostEnvironment for environment detection in PlayerService

[abdulrahmanelnory1]

What

• Refactor PlayerService to use IHostEnvironment interface for environment detection
• Remove direct access to Environment.GetEnvironmentVariable()

Why

• Follows ASP.NET Core recommended patterns for environment detection
• Uses framework-provided IHostEnvironment instead of manual environment variable checks

Changes

• Replace Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") with _hostEnvironment.IsDevelopment()
• Update service constructor to inject IHostEnvironment

Summary by CodeRabbit

• Refactor
  • Improved internal environment detection mechanism to use standard framework utilities, enhancing code maintainability and reliability.

Walkthrough

The PR refactors the PlayerService class to accept IHostEnvironment via dependency injection. It replaces manual environment variable checking with the built-in IHostEnvironment.IsDevelopment() method and removes the associated static constants.

Changes

Cohort / File(s)	Change summary
PlayerService refactoring src/Dotnet.Samples.AspNetCore.WebApi/Services/PlayerService.cs	Added IHostEnvironment parameter to constructor. Replaced Environment.GetEnvironmentVariable() with hostEnvironment.IsDevelopment(). Removed obsolete static environment constants.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~5-15 minutes

• Verify the constructor parameter addition is correctly injected and used
• Confirm IHostEnvironment.IsDevelopment() behaves identically to the previous environment variable check
• Ensure all dependent code paths still execute correctly with the new environment check

Possibly related issues

• Refactor PlayerService to use IHostEnvironment instead of Environment.GetEnvironmentVariable #320 — Directly implements the same IHostEnvironment injection and environment variable replacement refactor described in this issue.

🔇 Additional comments (3)

src/Dotnet.Samples.AspNetCore.WebApi/Services/PlayerService.cs (3)

57-60: Perfect use of IHostEnvironment.IsDevelopment().

The replacement of direct environment variable checking with hostEnvironment.IsDevelopment() is exactly the right approach. This follows ASP.NET Core best practices, eliminates magic strings, and improves code maintainability.

---

1-5: The AutoMapper using statement is correctly added; no additional using directives are required.

IHostEnvironment is not used in this file, so the concern about a missing using Microsoft.Extensions.Hosting; directive is unfounded. The project has ImplicitUsings enabled, which automatically includes common framework namespaces anyway. The four explicit using statements shown are appropriate for the code's actual dependencies.

Likely an incorrect or invalid review comment.

---

7-13: Refactor to use IHostEnvironment instead of Environment.GetEnvironmentVariable for environment detection.

The current implementation at line 71 uses Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") to check the development environment. This should be refactored to inject IHostEnvironment via dependency injection and use IHostEnvironment.IsDevelopment(), which is the ASP.NET Core recommended approach.

Update the constructor to accept IHostEnvironment hostEnvironment, add the using Microsoft.Extensions.Hosting; statement, and replace the environment check with hostEnvironment.IsDevelopment().
