ASP.NET Course with the SVILUPPATORE MIGLIORE method
Build scalable, secure and high-performance APIs and web applications. The backend framework chosen by Stack Overflow, Microsoft and thousands of enterprise companies worldwide.
1-on-1 Mentor On YOUR code Measurable results
Your team builds APIs and web applications with ASP.NET. Perhaps you still have code on ASP.NET Framework 4.x. Perhaps you are on .NET Core but the architecture has grown without a plan, controllers doing everything, dependency injection half-used and zero automated tests.
The result: a backend that works, but is fragile, slow to evolve and impossible to scale without rewriting critical pieces.
ASP.NET Core is the most performant web framework in the .NET ecosystem, in TechEmpower benchmarks it outperforms Node.js, Django and Spring Boot in almost every category. But the framework's performance is worthless if the code is written poorly.
If you are a CTO who needs robust and scalable APIs, a team leader who wants to introduce clean architectures in the backend, or a senior developer who wants to master ASP.NET Core at the enterprise level, this path is designed for you.
Why ASP.NET Core is the enterprise choice for backend
ASP.NET Core needs no introduction for those working in the Microsoft ecosystem. But few teams truly exploit its potential:
- Top-tier performance, Up to 7 million requests per second. Faster than Express.js, FastAPI and Spring Boot.
- Cross-platform, Runs on Windows, Linux and macOS. Deploy on Azure, AWS, Docker, Kubernetes.
- Mature ecosystem, Entity Framework Core, SignalR, gRPC, Blazor: all natively integrated.
- Enterprise security, Identity, JWT, OAuth2, policy-based authorization: enterprise-grade authentication out of the box.
What you learn: the complete programme

PHASE 1: ASP.NET Core Foundations (Weeks 1-4)
- 1
How to build APIs that don't become a nightmare after 6 months
Many .NET backends grow by addition: one controller at a time, one endpoint at a time, without an architecture to guide decisions. The result is 800-line controllers, inconsistent routing and documentation nobody updates, because nobody set the right structure from the beginning. Here you build the architecture of a professional API before writing the first endpoint.
Programma
- Minimal API vs ControllerNot just a style question, an architectural choice with concrete implications for testability, organisation and code scalability
- Advanced routing and versioningHow to structure URLs that still make sense in 2 years and how to add v2 without breaking those still on v1
- Dependency Injection in depthHow to register services with the correct lifecycle, the wrong choice between Transient and Scoped is the cause of the hardest bugs to reproduce
- Options patternHow to read configuration in a type-safe, startup-validated way instead of Configuration['key'] strings scattered across every class
- OpenAPI with SwaggerAutomatic documentation that always reflects the real code and how to generate type-safe clients for frontend teams in one command
- Problem Details (RFC 9457)How to return structured errors the client can interpret instead of generic messages that help nobody
Risultato
APIs designed to last: versionable, documented, with clear conventions the team follows naturally instead of working around.
- 2
What really happens to every HTTP request (and how to control it to the millisecond)
The middleware pipeline is the heart of ASP.NET Core. Every request traverses it from start to finish. Those who know it well add logging, authentication, caching and error handling in one place. Those who don't duplicate the same logic in every controller, and every new cross-cutting requirement becomes an intervention across dozens of files. Here you learn to build custom middleware and use the pipeline as the single control point for cross-cutting behaviour.
Programma
- Request pipeline in depthExecution order, path branching, short-circuit, why middleware order is not arbitrary and getting it wrong produces unexpected behaviour
- Custom middlewareHow to build a logging middleware that automatically adds correlation ID, tenant ID and trace context to every request
- Global exception handling with ProblemDetailsHow to transform any unhandled exception into a structured response without try/catch in every controller
- Output caching and response cachingHow to reduce server load for endpoints with rarely-changing data, configuration and invalidation strategy
- Health checks and readiness probesHow to expose endpoints that Kubernetes and Azure use to know whether the application is ready to receive traffic
- Structured logging with SerilogHow to write logs that can be queried, filtered and correlated, instead of text strings that help nobody in production
Risultato
Total control over every HTTP request. Structured logging, consistent error handling, optimised performance. No surprises in production.
- 3
Security that holds up to a security audit, not just 'works with Postman'
Poorly implemented security is worse than no security: it gives false confidence. Misconfigured JWTs, overly permissive CORS, absent rate limiting, secrets in code: these are exactly the vulnerabilities penetration testers find first, and that developers don't notice because the application works. This module builds real security, defensible in front of a security audit.
Programma
- ASP.NET IdentitySetup, table customisation, custom claims, how to integrate it into your domain model instead of using it as a black box
- JWT authentication and refresh token patternHow to implement stateless authentication that scales and how to handle token revocation without a session database
- OAuth2/OpenID ConnectHow to integrate Google, Microsoft, Entra ID as identity providers and when it makes sense to build your own
- Policy-based authorizationHow to build complex authorisation rules depending on claims, roles and resources, without if/else in action methods
- CORS, rate limiting, anti-forgeryThe three security settings almost always missing or misconfigured in ASP.NET Core backends
- Data Protection API and secretsHow to manage encryption keys, connection strings and certificates without ever putting them in a text file
Risultato
Backend secure by design. Enterprise-grade authentication that satisfies compliance requirements and that a security audit won't crack on the first try.
PHASE 2: Architecture and Data (Weeks 5-10)
- 4
EF Core in APIs: the traps that slow everything down and how to avoid them
EF Core used correctly in an ASP.NET Core API is a very powerful tool. Used badly, it is the cause of 90% of performance problems. N+1 queries, DbContext with the wrong lifetime, Include on every endpoint even when not needed: these are the real problems that slow .NET backends in production, and almost nobody notices them during development. Here you learn to use EF Core correctly in APIs, with measurable optimisations and patterns that hold up under load.
Programma
- DbContext scoping in ASP.NET CoreWhy Scoped is the correct choice and what happens when it accidentally becomes Singleton or Transient in a multi-request application
- Query optimisation for APIsProjections with Select, split queries, AsNoTracking for read-only operations, how to never load more data than needed
- Fluent API for rich domain modelsOwned types for value objects, TPH for entity hierarchies, how to keep the model clean without compromising queries
- Migrations in teamsHow to manage parallel branches with concurrent migrations without unresolvable conflicts and without breaking staging databases
- Raw SQL when neededHow to execute complex queries while keeping EF advantages, type safety on results and the change tracker respected
- Interceptors for audit trailsHow to automatically log every database change with who made it and when, without touching application code
Risultato
Performant, maintainable data access. Zero N+1 problems, optimised queries, migrations that don't cause fear.
- 5
The architecture that lets you add features without breaking existing ones
An application that grows without architecture quickly becomes a tangle where every new feature requires touching 10 different files. The problem is not domain complexity: it's that without an explicit structure every change becomes a risk, and every developer ends up afraid to touch other people's code. Here you build the structure that makes change predictable and safe.
Programma
- Clean Architecture in ASP.NET CoreDomain, application, infrastructure, a single direction of dependency, a controller that doesn't know the DbContext
- CQRS with MediatRHow to separate read operations from write operations, dedicated handlers that do one thing and do it well
- Vertical Slice ArchitectureHow to organise code by feature instead of by technical layer, the pragmatic alternative when Clean Architecture is excessive
- Validation pipeline with FluentValidationCentralised validation in the application layer, no more duplicated validation in controllers and services
- Domain events and integration eventsHow to notify other modules when something happens without direct coupling between modules
- Modular monolithHow to separate code into modules with explicit boundaries without the operational costs of microservices
Risultato
Architecture the team can evolve independently. Every feature is isolated, testable and independent. Adding something new doesn't break anything existing.
- 6
Real-time and background: the things that happen while the user isn't watching
Modern applications are not just request/response. Notifications arrive in real time. Emails are sent in the background. Reconciliations run at night. Those who don't know the right tools build timers, polling and workarounds that work in development but in production lose messages, block threads and consume resources uncontrollably. Here you build the parts of the application that work even when nobody calls them, with solid and monitorable patterns.
Programma
- SignalRHow to push notifications from server to client the moment an event happens, without polling or manual refresh
- IHostedService and BackgroundServiceHow to build services running in parallel to the application for periodic processing and message queues
- Hangfire and Quartz.NETJob scheduling with automatic retry, monitoring dashboard and job state persistence
- Message queues with RabbitMQ and Azure Service BusHow to decouple producer and consumer so they can scale independently
- Outbox patternHow to guarantee a message is published only if the transaction succeeded, no ghost messages, no lost messages
- gRPC for inter-service communicationEnd-to-end type safety, superior performance to REST for synchronous internal calls between microservices
Risultato
Your applications handle real-time and background scenarios with solid patterns. No job disappearing into the void. No late-arriving notification.
- 7
APIs without tests are time bombs: the strategy that actually works
Testing APIs is different from testing classes. You need to test routing, authentication, serialisation, middleware and the real database call. Those who stop at unit tests of business logic have false confidence: the integrations between layers are exactly where the most serious bugs hide, the ones that only emerge in production. Here you build the right testing strategy for every level, with tools that detect real bugs.
Programma
- Service unit testsHow to test business logic in isolation with minimal mocks, without building a mini-application for every test
- Integration tests with WebApplicationFactoryHow to test the entire ASP.NET Core pipeline in memory, real routing, real middleware, real database
- TestContainersReal SQL Server or PostgreSQL in Docker for tests, no behavioural difference between tests and production
- Contract testing with PactHow to verify that your backend and frontend actually understand each other, without an always-broken integration environment
- Performance testing with k6 and NBomberHow to simulate 1,000 concurrent users and find where the API breaks before real users do
- Test pyramid for enterprise teamsHow many tests of each type, what to cover with unit and what with integration, the strategy that balances coverage and speed
Risultato
Safe releases with end-to-end coverage. Bugs found in automated tests. Regressions discovered within seconds of commit, not by customers on Monday morning.
PHASE 3: Production and Performance (Weeks 11-14)
- 8
How to take APIs from 100 to 100,000 requests per second without rewriting everything
ASP.NET Core is already among the fastest frameworks in the world. But code written without attention to performance can negate this advantage. Most performance problems don't come from the framework: they come from missing cache, badly-used async, unoptimised database connections, all things solvable in hours if you know where to look. Here you measure, optimise and verify in the correct order, with tools that give certain answers.
Programma
- Three-level cachingIn-memory for session data, Redis for shared data between instances, output caching for complete responses, when to use which
- Response compression and HTTP/2How to reduce every response payload and multiplex requests over the same socket
- Async end-to-end with CancellationTokenHow to free threads while waiting for the database or an external call, the foundation for scaling without adding servers
- Connection pooling and resource managementHow to manage database connections so they don't exhaust the pool under load
- BenchmarkDotNet to measure optimisationsHow to verify the applied optimisation actually improved things and didn't make them worse
- Profiling with dotTrace and Application InsightsHow to find the method consuming 40% of CPU in a production application
Risultato
APIs that hold up under production load. Performance measured with data, not guessed. And when traffic doubles, you already know what to do.

From commit to production in 10 minutes: automating the entire lifecycle
The best code in the world is useless if you can't distribute it reliably. Every manual deploy is a risk. Every staging environment different from production is a time bomb. A well-built CI/CD pipeline eliminates the entire category of errors that happen 'only in production'. Here you build complete automation from commit to production, with rollback, monitoring and zero downtime.
Programma
- Optimised Dockerfile for ASP.NET CoreMulti-stage build producing 80MB images instead of 800MB, secure, reproducible and fast to distribute
- Docker Compose for local developmentHow to have SQL Server, Redis, RabbitMQ and the application running with a single command
- Azure App Service and Container AppsHow to choose between the two, configure automatic scaling and do blue-green deployment without downtime
- CI/CD with GitHub Actions and Azure DevOpsBuild, test, image push and production deploy, all automatic on merge to main
- Application Insights and OpenTelemetryDistributed tracing, custom metrics and structured logs, how to know exactly what's happening in production
- Feature flagsHow to gradually release a feature to 5% of users and measure it before enabling it for everyone
Risultato
Automated deploy and continuous monitoring. From commit to production in minutes. No more frightening Fridays before a release.

AI in APIs: from experiment to product feature that generates value
Integrating an LLM into an API is not difficult. Doing it reliably, measurably, securely and cost-effectively in production is a completely different matter. Most teams that integrate AI do it as an experiment: an endpoint that calls OpenAI, without error handling, without cost control, without a way to measure whether it actually works. This module shows how to do it correctly, with an end-to-end capstone project applying all the patterns from the path.
Programma
- Semantic Kernel to integrate GPT in ASP.NET Core APIsPlugins, function calling, memory, how to build an AI assistant that uses your APIs as tools
- Azure OpenAI Service with cost managementHow to calculate cost per request, set budget alerts and optimise prompts to reduce tokens
- RAG pattern in the APIHow to answer questions about company documents using Azure AI Search as a vector database, without making up data
- Capstone projectComplete end-to-end API architecture, authentication, CQRS, EF Core, SignalR, automated tests, CI/CD and AI integration
- Final code review with the architectAnalysis of the produced architecture, identification of improvement points and consolidation of patterns
- Post-course evolution planHow to keep growing, which components of your current project you can improve immediately
Risultato
You have built a complete enterprise API, tested, documented and production-ready. You know how to integrate AI as a core feature, not as a gadget.
The method: Progressive Mastery Architecture
We apply Progressive Mastery Architecture to ASP.NET Core. We start from the team's existing code, identify weak points and build the target architecture together.
We don't rewrite everything. We evolve progressively: controller by controller, endpoint by endpoint, introducing patterns and tests where they are most needed.
- Assessment, We analyse the current architecture, identify technical debt and define priorities.
- Reference architecture, We define the target structure (Clean Architecture, CQRS, or the most suitable approach for the context).
- Guided refactoring, Biweekly refactoring sessions on real code with code review.
- Testing, We introduce automated tests starting from the most critical points.
- Autonomy, The team acquires the method to continue evolving the code independently.

Who is Matteo Migliore
What professionals who have taken the path say
Those who study with Matteo have the opportunity to access a very meaningful and concrete experience, entering the world of software development with a reliable and competent guide.
His training is a real opportunity for young people who want to pursue a career as a software architect.
I definitely recommend him, especially for the professionalism he has always shown and his ability to explain numerous topics that are normally not covered in these types of courses.
The WPF course I had the fortune to take with Matteo Migliore literally opened up an incredible world for me, allowing me to acquire all the techniques that will enable me to tackle increasingly important projects.
I definitely recommend Matteo for the technical content and the experience he brings; the training journey was also rich in anecdotes where he shared his experiences going all the way back to when he was a child.
I recommend Matteo's course especially to beginners and anyone who needs to learn how to structure an application, because this way you can start already with a correctly built architecture.
One difference I notice compared to other courses is a great passion for training, understood in a very broad sense. It is a mission for them, and beyond the specific WPF course topics, I always find tips and suggestions on cross-cutting subjects like design, software control and testing — which gives me something extra in my overall development approach.
Often there is little time and great difficulty managing on your own the issues you encounter daily, and if you tend to limit yourself to your own knowledge you end up stuck in your own mistakes.
Going back over things I had studied at university, explained step by step in a new language I had not studied before, was extremely useful.
I turned to our consultant, Matteo Migliore, to enter this new world.
Thanks to the course I learned a programming approach built in a much more sensible way than what I was doing before.
I recommend Matteo because he is a very competent person who loves his work and cares about helping others, making them more productive and more capable of mastering technology.
What I liked most was the new management of the project structure: separating the UI from the design layer, and in particular not writing code directly in the UI but structuring it properly.
Matteo doesn't simply read from a pre-prepared script but is able to go deeper into syntactic elements and design patterns, perfectly following the needs of whoever is learning.
