Can I use this with existing database schemas?

Yes, the skill provides patterns for implementing IXafEntityObject and IObjectSpaceLink manually if you cannot inherit from the default BaseObject.

Why does this skill emphasize virtual properties?

XAF requires all properties to be virtual to enable EF Core's change-tracking and lazy loading proxies, which are essential for UI notifications and data performance.

How do I handle many-to-many relationships?

The skill recommends using an explicit join entity to allow for better control and the addition of extra metadata fields within the XAF UI.

Does it handle EF Core migrations?

Yes, it includes standard CLI and Package Manager Console commands for creating and applying migrations within the XAF architecture.

What is the difference between AddDbContext and AddDbContextFactory?

XAF requires AddDbContextFactory because it manages its own ObjectSpace lifecycle, requiring fresh context instances on demand rather than relying on a scoped request context.
