Entity Framework 6

Trigger On

• working in an EF6 codebase on .NET Framework or modern .NET
• deciding whether to keep EF6, move to modern .NET runtime, or port to EF Core
• reviewing EDMX, code-first, or legacy ASP.NET/WPF/WinForms data access
• planning a data layer migration strategy

Workflow

1. Audit current EF6 usage before planning any migration. Identify which features the codebase depends on:

   // Common EF6-specific patterns to inventory:
   // - EDMX designer models (check for *.edmx files)
   // - ObjectContext vs DbContext usage
   // - Lazy loading with virtual navigation properties
   // - Database.SqlQuery<T>() for raw SQL
   // - Stored procedure mappings in model
