Research direction

Start by reading the proposed extension method in the linked gist and compare its handling of DataAnnotations, default constraints, and Identity tables with EF Core's model-building behavior. Determine the intended scope for a modelBuilder.SetDefaults-style feature and define completion criteria for mapping table and property attributes to SQL defaults.

Description

area-model-building customer-reported
Is your feature request related to a problem?

I was trying to keep DataAnnotations from a legacy code we have made with .NET Framework, but rewriting all the defaults constraints for MS SQL as fluent in the OnModelCreating method was awful.

Describe the solution you'd like

Something simple, like modelbuilder.SetDefaults() and read the table attribute and the attributes of their properties.

Additional context

I made an extension method that works well, including the Identity tables:
