Please check the settings in the CodeRabbit UI or the You can disable this status message by setting the WalkthroughThis pull request implements refinements in both client and server components. On the client side, enhancements focus on improved cancellation token handling in a core component, updated routing for product pages, and refined queries limiting results. On the server side, modifications adjust cache purging and entity deletion logic in the product controller while expanding concurrency checks in the database context. These changes strengthen error handling and resource management across the application. Changes

232-240: Add safety check before creating new CancellationTokenSource.While disposing of the CTS is good practice, creating a new one immediately after could lead to race conditions if the component is being disposed.
Consider this safer implementation:
protected void Abort() { if (cts.IsCancellationRequested is false) { cts.Cancel(); } cts.Dispose(); - cts = new(); + if (!IsDisposed) + { + cts = new(); + } } + private bool IsDisposed { get; set; }This prevents creation of a new CTS if the component is being disposed.
249-260: Improve the disposal pattern implementation.The current implementation has potential race conditions and could be improved to follow .NET disposal pattern best practices.
Consider this enhanced implementation:
+ private volatile bool _disposed; + protected virtual async ValueTask DisposeAsync(bool disposing) { - if (disposing) + if (_disposed) + { + return; + } + + if (disposing) { + _disposed = true; await PrerenderStateService.DisposeAsync(); - if (cts.IsCancellationRequested is false) - { - cts.Cancel(); - } + try + { + cts.Cancel(); + } + finally + { + cts.Dispose(); + } - cts.Dispose(); } }This implementation:
- Adds proper disposal guard
- Ensures CTS is always disposed even if Cancel throws
- Uses volatile flag to prevent race conditions

61-63: LGTM! Performance optimization applied.The query now limits similar products to 10 items, which aligns with the UI's display capacity and reduces data transfer.
78-80: LGTM! Performance and logic improvements applied.The query now:
- Limits sibling products to 10 items
- Explicitly excludes the current product using Id comparison
src/Templates/Boilerplate/Bit.Boilerplate/src/Server/Boilerplate.Server.Api/Controllers/Products/ProductController.cs (2)
81-81: LGTM! Cache purging now handles product names correctly.The cache purging logic properly includes and escapes the product name in the URL, aligning with the new routing pattern.
93-102: LGTM! Improved error handling in delete operation.The changes enhance robustness by:
- Validating product existence before deletion
- Using the actual entity data for cache purging
- Maintaining proper concurrency checks
src/Templates/Boilerplate/Bit.Boilerplate/src/Server/Boilerplate.Server.Api/Data/AppDbContext.cs (1)
94-94: LGTM! Enhanced concurrency handling.The change ensures proper concurrency checks for both modified and deleted entities.
src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Components/Pages/ProductPage.razor (1)
1-3: LGTM! Improved URL patterns with consistent product name inclusion.The route attributes now:
- Consistently include product name in URLs
- Maintain culture parameter support
- Keep response caching configuration
