Trellis.EntityFrameworkCore

NuGet Package

EF Core conventions and helpers for Trellis value objects, Maybe<T>, and Result-based persistence.

Installation

dotnet add package Trellis.EntityFrameworkCore

Quick Example

using Microsoft.EntityFrameworkCore;
using Trellis;
using Trellis.EntityFrameworkCore;

protected override void ConfigureConventions(ModelConfigurationBuilder configurationBuilder) =>
    configurationBuilder.ApplyTrellisConventions(typeof(AppDbContext).Assembly);

// Reflection-free alternative — generated at compile time, no assembly scan:
//   configurationBuilder.ApplyTrellisConventionsFor<AppDbContext>();

Maybe<Customer> customer = await dbContext.Customers.FirstOrDefaultMaybeAsync(cancellationToken);
Result<int> saved = await dbContext.SaveChangesResultAsync(cancellationToken);

Key Features

  • Apply Trellis value converters and owned-type conventions with one registration point.
  • Query Maybe<T> naturally instead of dropping to storage-specific null handling.
  • Return Result<int> or Result from save operations instead of throwing on expected failures.
  • Idempotent inserts on a unique constraint via db.TryInsertUniqueAsync(entity, ct) — duplicate-key violations surface as a failed Result<TEntity> carrying an Error.Conflict with reason code "duplicate.key" and the provider-extracted ConstraintName / ConstraintTableName telemetry fields, so worker outboxes and "save unless exists" deduplication never throw on redelivery.
  • Cursor-based seek pagination via IQueryable<T>.ToPageAsync(pageSize, cursor, keySelector, …) — returns Result<Page<T>>, composes with PageBuilder and CursorCodec, and never throws on malformed input.
  • RepositoryBase<TAggregate, TId> — staging-only base class (Add/Remove/Query/Exists/Count).
  • IUnitOfWork / EfUnitOfWork<TContext> — single commit boundary for staged changes.
  • TransactionalCommandBehavior — Mediator pipeline behavior that auto-commits after successful command handlers (requires Mediator pipeline registration). Also commits on Result.FailAfterCommit<T>(error) outcomes so persist-on-failure handlers (e.g., a worker recording a permanent-failure transition) can stage state alongside the failed result.

Trellis.ServiceDefaults

Opinionated service composition defaults for Trellis web services. Provides a tiered builder that wires ASP integration, Mediator behaviors, FluentValidation, resource authorization, actor providers, and EF Core Unit of Work in canonical order.
Trellis.EntityFrameworkCore.Outbox

Transactional outbox for Trellis. Atomically captures aggregate domain events to an EF Core table in the same transaction as the aggregate change, then relays them to Trellis domain-event handlers — durable, at-least-once, in-process dispatch.
