Does this skill support production diagnostic tools?

The skill includes guidance on using advanced CLI tools like dotnet-trace for performance, dotnet-dump for memory analysis, and dotnet-counters for real-time monitoring.

How does this skill help with Dependency Injection (DI) errors?

It provides specific patterns to identify missing registrations, resolve circular dependencies, and fix captive service lifetimes where singletons hold scoped services.

Can it help optimize Entity Framework Core queries?

Yes, it detects N+1 query problems and provides implementation patterns for eager loading, split queries, and AsNoTracking for read-only operations.

How does it handle ASP.NET Core middleware issues?

It provides a blueprint for the correct middleware execution order and offers diagnostic code snippets to trace requests through the pipeline to find where responses are being blocked or mismanaged.
