There was a problem hiding this comment.
Hey @ArgoZhang - I've reviewed your changes - here's some feedback:
- The Layout.razor changes reference private fields
_enableErrorLoggerand_showToast—make sure those backing fields are declared and initialized so you don’t introduce runtime errors. - Your Dispose method calls
GC.SuppressFinalize(this)even though there’s no finalizer; either remove that call or add a matching finalizer to avoid misleading code. - Consider renaming the
HandlerExceptionmethod toHandleExceptionto follow standard verb-based naming conventions and reduce confusion.
Here's what I looked at during the review
