150-150: Consider enhancing memory formatting.The current formatting only shows MB. Consider adding more units for better readability.
Here's an improved implementation:
- static string FormatMemory(long bytes) => $"{bytes / (1024.0 * 1024.0):F2} MB"; + static string FormatMemory(long bytes) + { + string[] units = ["B", "KB", "MB", "GB"]; + int unitIndex = 0; + double size = bytes; + + while (size >= 1024 && unitIndex < units.Length - 1) + { + size /= 1024; + unitIndex++; + } + + return $"{size:F2} {units[unitIndex]}"; + }src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Services/PubSubService.cs (2)
24-31: Be mindful of concurrent modifications
UsingweakHandlers.ToArray()is a common pattern to avoid enumeration errors ifweakHandlerschanges. However, you still risk race conditions if unsubscribes occur while publishing. Consider a clearer locking or concurrency strategy for multi-thread scenarios.
67-129: Validate reflection invocation & consider performance
- The array literal syntax
[payload]is non-standard in older C#. Verify that it’s valid in your target C# version or replace withnew object?[] { payload }.- Reflection can be expensive; in high-frequency scenarios, caching a delegate for invocation might provide better performance.
- Overall approach for managing weak references is solid, ensuring garbage-collected subscribers don’t linger in memory.

3-3: Adoption of partial class is appropriate for Blazor code-behind.
The switch to a partial class is consistent with best practices in Blazor projects, allowing separation of markup and logic.
21-25: Asynchronous disposal method adheres to modern IAsyncDisposable practices.
Unsubscribing fromPubSubServiceand then callingawait base.DisposeAsync(disposing)is aligned with recommended patterns and helps prevent resource leaks in asynchronous operations.src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Components/Layout/IdentityHeader.razor.cs (2)
3-3: Use of partial class is valid and clear.
Defining a partial class aligns with Blazor’s component model, keeping code organization flexible.
54-58: Async disposal pattern is well-implemented.
Invoking the unsubscribe action ensures cleanup, and calling the base class’sDisposeAsyncmaintains consistency across the component lifecycle.src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Components/Pages/Identity/SignIn/SignInPage.razor.cs (2)
7-7: Partial class use is appropriate.
No issues with adopting a partial class structure, as this is common in Blazor components for better code separation.
228-232: Transition to asynchronous disposal is correctly handled.
Unsubscribing fromPubSubServicewithinDisposeAsynchelps avoid event leaks. The call toawait base.DisposeAsync(disposing)is likewise essential for proper cleanup.src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Components/Layout/JsBridge.razor.cs (1)
3-3: LGTM! Improved disposal pattern implementation.The transition to async disposal pattern and proper base class cleanup is a good improvement for resource management.
Also applies to: 36-40
src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Components/Layout/DiagnosticModal.razor (1)
68-71: LGTM! Well-integrated UI control for GC.The new GC button follows the existing UI patterns and is appropriately placed within the diagnostic tools section.
src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Components/Layout/DiagnosticModal.razor.cs (1)
10-10: LGTM! Improved disposal pattern implementation.The transition to async disposal pattern and proper cleanup of subscriptions is a good improvement.
Also applies to: 193-197

1-1: Import usage is valid
No concerns here; reflection is needed for the subsequentWeakSubscriptionclass.
3-3: Namespace declaration is consistent
No issues identified with the new namespace.
42-44: Check handling of persistent messages & dictionary initialization
- Re-check
GetOrAdd(message, _ => []): it's the same potential issue with[]usage. Prefer a valid list initializer, e.g.new List<WeakSubscription>().- If multiple persistent items share the same message, you currently handle only the first one (given the single
TryTake). Confirm whether this is the desired logic.Also applies to: 46-46, 51-51
62-62: Method rename adheres to conventions
Renaming fromhandleExceptiontoHandleExceptionaligns well with .NET naming standards.
