What is .NET Expert?
The .NET Expert skill transforms your AI agent into a senior-level engineer specializing in modern ASP.NET Core development and enterprise architecture. By integrating this into Openclaw Skills, you gain an assistant capable of architecting Modular Monoliths, implementing MediatR-based CQRS patterns, and enforcing strict clean architecture principles. It prioritizes production-grade practices like the Result pattern over traditional exception-based business logic, ensuring your backends are resilient, testable, and maintainable.
.NET Expert Use Cases
- Architecting scalable Modular Monoliths organized by feature and domain.
- Implementing robust Minimal APIs with JWT authentication and ASP.NET Identity.
- Developing complex business workflows using MediatR commands and queries.
- Optimizing database performance with Entity Framework Core 9 projection and eager loading.
- Ensuring data integrity through automatic FluentValidation pipeline behaviors.
How .NET Expert Works
- Identifies .NET or C# related triggers within your development context.
- Applies a feature-first organizational structure to your project modules (Core, Application, Infrastructure).
- Generates asynchronous, decoupled handlers using MediatR to separate read and write operations.
- Integrates FluentValidation and Result patterns to handle business rules without throwing costly exceptions.
- Configures Entity Framework Core 9 with optimized mapping and global query filters for features like soft-delete.
.NET Expert Setup
To utilize this skill within Openclaw Skills, ensure your development environment is ready with the latest .NET SDK. You can initialize your infrastructure components using the following commands:
# Install Entity Framework Core tools
dotnet tool install --global dotnet-ef
# Add a new migration for a specific module
dotnet ef migrations add InitialCreate -p src/Users.Infrastructure -s src/Api
# Apply migrations to the database
dotnet ef database update -p src/Users.Infrastructure -s src/Api
.NET Expert Data Schema & Taxonomy
The skill organizes code into a standardized Modular Monolith structure to ensure scalability and separation of concerns:
| Layer | Responsibility | Directory Path |
|---|---|---|
| Api | ASP.NET Core Host & Minimal API Endpoints | /src/Api |
| Domain Core | Entities, value objects, and domain interfaces | /src/Modules/[Name].Core |
| Application | MediatR commands, queries, and validators | /src/Modules/[Name].Application |
| Infrastructure | EF Core DbContext, migrations, and external clients | /src/Modules/[Name].Infrastructure |
| Shared | Common Result types, audit interfaces, and cross-cutting logic | /src/Shared |
.NET Expert Advanced Features
- Global Validation Behavior: Automatically validates every MediatR request before it reaches the handler.
- Smart Audit Tracking: Automatically populates CreatedAt and UpdatedAt fields during SaveChangesAsync.
- Idempotent Scripting: Generates production-ready SQL migration scripts for CI/CD pipelines.
- Strongly-Typed IDs: Implements value objects for IDs to eliminate primitive obsession errors.
- Result Pattern Matchers: Provides functional matching for API responses to handle Success and Error states gracefully.
