Document usage in how-to guides + +**Complexity:** Medium +**Value:** High - enables code-first auto-generation immediately + +### Phase 2: Assembly-Level Scanning +**Deliverable:** Generate manifests from `[assembly: GenerateManifest(...)]` + +1. Implement `AnalyzeAssembly` to scan compilation +2. Support assembly-level attribute with filtering rules +3. Add configuration options (include/exclude patterns) +4.

Support custom attributes for business rules + +**Complexity:** Medium +**Value:** High - parity with manual manifest creation + +### Phase 4: DbContext Model Introspection (Optional) +**Deliverable:** Generate manifests from EF Core `OnModelCreating` + +**Option A: Syntactic Analysis (Source Generator)** +- Analyze `modelBuilder.Entity()` calls syntactically +- Limited to simple, statically analyzable configurations +- Complexity: High, Value: Medium + +**Option B: Runtime Reflection (MSBuild Task)** +- Load compiled assembly and read `IModel` via reflection +- Full fidelity with all EF Core features +- Requires MSBuild task instead of source generator +- Complexity: Medium, Value: High + +**Recommendation:** Defer to v0.2.0, gather user feedback on Phase 1-3 first. + +### Phase 5: Integration with Snapshot/Diff +**Deliverable:** Auto-save generated manifests as snapshots + +1.

Users can still use DSL for complex scenarios. Attributes are just convenience. + +### Risk: Breaking changes in EF Core +**Mitigation:** Target stable EF Core APIs. For DbContext introspection, use runtime reflection (Option B) which is more resilient. + +## Alternative Approaches Considered + +### 1. Convention-Based Discovery (No Attributes) +**Example:** Scan all classes ending in "Entity" or implementing IEntity +**Rejected:** Too magical, conflicts with opt-in philosophy, high risk of false positives + +### 2. Fluent Configuration Files +**Example:** Manifest.cs file with fluent API configuration +**Rejected:** This already exists (Domain.Create() DSL), we want to reduce boilerplate + +### 3.

+ +### Traditional Approach Problems + +In typical .NET applications, business rules are scattered across: +- Property setters with throw statements +- Separate validator classes (FluentValidation, DataAnnotations) +- Application service methods +- Controller action methods + +This creates several issues: +- **Duplication** - Same rules repeated in multiple places +- **Inconsistency** - Different validation for API vs. domain vs. database +- **Fragility** - Easy to forget validation in one path +- **Poor discoverability** - Hard to find all rules for an entity + +### JD.Domain Approach + +JD.Domain provides a single source of truth for your domain: + +```csharp +// Define domain model and rules once +var domain = Domain.Create("ECommerce") + .Entity(e => e + .Property(c => c.Name) + .Property(c => c.Email)) + .WithRules(rules => rules + .Invariant("Name.Required", c => !string.IsNullOrWhiteSpace(c.Name)) + .Invariant("Email.Valid", c => c.Email.Contains("@"))) + .Build(); +``` + +Then generate or validate everywhere: +- ✅ Construction-safe domain types with `Result` +- ✅ FluentValidation validators for API request validation +- ✅ EF Core configurations for database constraints +- ✅ Runtime validation in services +- ✅ ASP.NET Core middleware for automatic API validation + +## Key Features + +### 1.

You've created: + +1. **Domain entities** - Simple POCO classes with standard data annotations +2. **Automatic manifest generation** - Metadata extracted automatically from your code at build time +3. **Business rules** - Declarative rules that validate entity state +4. **Runtime validation** - Automatic validation using the domain engine + +**No manual string writing was required!** The manifest was generated automatically from your entity classes. + +## Key Concepts Demonstrated + +### 1. Automatic Manifest Generation + +The `ManifestSourceGenerator` analyzes your entity classes at compile-time and automatically extracts: +- Property names and types +- Data annotations ([Key], [Required], [MaxLength]) +- Nullability information +- Table and schema names + +**No manual string writing required!** Your code is the source of truth. + +### 2. Opt-In Design + +Your `Customer` and `Order` classes use standard data annotations. JD.Domain attributes (`[DomainEntity]`) are explicit and opt-in - no magic discovery. + +### 3. Declarative Rules + +Rules are defined declaratively using lambda expressions: + +```csharp +.Invariant("Name.Required", c => !string.IsNullOrWhiteSpace(c.Name)) +.WithMessage("Customer name cannot be empty") +``` + +This is more maintainable than scattering validation logic throughout your codebase. + +### 3. Separation of Concerns + +Your entities remain pure POCOs, while rules are defined separately. This makes it easy to: +- Test entities without validation logic +- Reuse entities across different contexts +- Version rules independently from entities + +### 4. Explicit Validation + +Validation is explicit - you call `engine.Evaluate()` when you want to validate. This gives you full control over when validation happens. + +## Next Steps + +Now that you've built your first domain model, explore more features: + +### Add EF Core Integration + +Apply domain configurations to Entity Framework Core: + +```bash +dotnet add package JD.Domain.EFCore +``` + +See the [EF Core Integration Tutorial](../tutorials/ef-core-integration.md) for details. + +### Generate Rich Domain Types + +Create construction-safe types that enforce invariants: + +```bash +dotnet add package JD.Domain.DomainModel.Generator +``` + +See the [Domain Model Generator Tutorial](../tutorials/source-generators.md) for details. + +### Add ASP.NET Core Validation + +Automatically validate API requests: + +```bash +dotnet add package JD.Domain.AspNetCore +``` + +See the [ASP.NET Core Integration Tutorial](../tutorials/aspnet-core-integration.md) for details. + +### Explore More Examples + +- **[Code-First Walkthrough](../tutorials/code-first-walkthrough.md)** - Complete code-first workflow +- **[Database-First Walkthrough](../tutorials/db-first-walkthrough.md)** - Add rules to existing EF entities +- **[Hybrid Workflow](../tutorials/hybrid-workflow.md)** - Mix both approaches with snapshots + +## Common Questions + +### How do I validate nested entities? + +Use the `Validator` rule type for context-dependent validation: + +```csharp +.Validator("Address.Valid", c => ValidateAddress(c.Address)) +.WithMessage("Customer address is invalid") +``` + +### Can I use async rules? + +Yes!
