Learning objectives

  • Master advanced asynchronous programming with async/await and Task.
  • Implement expert design patterns like Strategy and Observer.
  • Optimize performance through profiling and fine-tuned garbage collection.
  • Develop secure applications with encryption and authentication.
  • Integrate CI/CD and advanced unit tests with xUnit.
  • Build cross-platform apps with .NET MAUI.
  • Analyze and refactor legacy code for scalability.

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without expert C# mastery, your apps risk asynchronous crashes costing 20% less performance, security breaches exposing client data to 1M€ GDPR fines, time-consuming legacy refactorizations multiplied by 3, project delays doubled by GC bottlenecks, outpaced by agile teams.

  • 70% of senior devs stagnate without upskilling, losing promotions and innovative projects.

  • Invest 35h for x10 ROI gains in productivity and reliability.

Program

Module 1Asynchronous Programming: async/await, Tasks and Parallel (Visual Studio tools, real cases).

Dive into advanced asynchronism mechanisms, code complex flows with Task.WhenAll and ConfigureAwait, simulate intensive I/O scenarios through practical exercises on REST APIs, analyze common deadlocks, produce a scalable reactive app prototype, gain fluidity for enterprise projects.

Module 2Advanced Design Patterns: Strategy, Observer, Factory (SOLID principles, refactored deliverables).

Apply expert patterns for robust architectures, refactor monolithic code into decoupled modules via collaborative workshops, integrate native Dependency Injection, test real e-commerce cases, generate interactive UML diagrams, transform your apps into maintainable and scalable systems.

Module 3Performance Optimization: Profiling, GC tuning (dotTrace tools, benchmarks).

Identify bottlenecks with professional profilers, optimize memory using spans and pooled arrays, measure gains up to 40% on benchmark exercises, tune the garbage collector for high-load apps, develop a performant microservices service, boost deployments for zero critical latency.

Module 4Security and .NET MAUI: Encryption, authentication (Azure AD tools, cross-platform apps).

Secure your apps with AES and JWT, implement OAuth through practical labs, migrate to .NET MAUI for mobile/desktop, code an end-to-end secure hybrid app, simulate attacks and defenses, produce a deployable deliverable for app stores, protect your data from costly breaches.

Module 5Advanced Testing and CI/CD: xUnit, GitHub Actions (pipelines, 90% coverage).

Master advanced mocks and integration tests, configure automated CI/CD pipelines, achieve 90% coverage on real projects, integrate SonarQube for code quality, deploy in Docker containers, finalize with an expert code portfolio, automate for zero-defect deliveries.

Evaluation method

  • Daily technical quizzes, graded final project, self-assessment of skills.

Learning method

  • Interactive pedagogy, hands-on exercises, real business cases, personalized feedback.

Methods, materials and delivery

The Training C# Expert - Optimize Performance and Security program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training C# Expert - Optimize Performance and Security program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training C# Expert - Optimize Performance and Security program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
