Can it help with database migrations?

Yes, it provides expert guidance on Entity Framework Core code-first migrations, DbContext configuration, and database-specific optimizations for SQL Server, PostgreSQL, and MySQL.

Does this skill support older versions of .NET?

The skill is optimized for modern .NET (version 8 and higher). While many patterns are backward compatible with .NET 6 or 7, it is not intended for legacy .NET Framework 4.x projects.

Can it handle background processing?

Yes, the skill includes implementation patterns for IHostedService, BackgroundService, and integration with libraries like Hangfire or Quartz.NET for scheduled tasks.

Does it include support for authentication?

Absolutely. It specializes in implementing ASP.NET Core Identity, JWT token generation and validation, OAuth 2.0, and complex policy-based authorization handlers.
