Learning objectives

  • Master multithreading and parallelism for high-performance apps
  • Implement async/await and Task for smooth asynchronous processing
  • Optimize queries with advanced LINQ and lambda expressions
  • Develop ORMs with Entity Framework Core and migrations
  • Apply advanced design patterns like Singleton and Observer
  • Profile and debug high-performance C# applications
  • Build secure and scalable APIs with .NET

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 advanced C# mastery, 70% of devs lose 15h/week on costly multithreading bugs, leading to slow apps that drive away 40% of mobile users.

  • Untrained teams see projects overcost by 25% in maintenance, with critical downtimes impacting revenue up to 10k€/day.

  • Risk obsolescence against .NET 8: competitors scale 3x faster, lost patents on mediocre performance.

  • Invest 35h to avoid 200h of debugging, gain promotions and high-value projects starting tomorrow.

Program

Module 1Multithreading: parallel tasks with Task and PLINQ (tools, exercises, real cases)

Dive into multithreading by coding parallel tasks with Task Parallel Library, test PLINQ on massive datasets, analyze deadlocks through practical exercises, create a concurrent image processor to boost performance, deliver a production-ready thread-safe module, all in Visual Studio for immediate and motivating results.

Module 2Async/Await: reactive asynchronous programming (methods, tools, deliverables)

Transform your apps by refactoring blocking I/O with async/await, configure asynchronous chains on HTTP APIs, simulate real scenarios like web scraping, debug with advanced breakpoints, produce a scalable notification service, gain fluidity and responsiveness for delighted users.

Module 3Advanced LINQ: expressive and optimized queries (expressions, exercises)

Master LINQ by building complex queries on XML/JSON, optimize with IQueryable for EF, chain aggregations and joins on live databases, solve performance challenges via benchmarks, export dynamic reports, become an expert in efficient and elegant data manipulation.

Module 4Entity Framework Core: advanced ORM and migrations (models, tools)

Model rich domains with Code First, migrate schemas live on SQL Server, integrate lazy/eager loading for optimal queries, manage complex relationships through business exercises, secure with owned types, deploy a complete and persistent CRUD, reach pro level in .NET persistence.

Module 5Design Patterns and Best Practices: C# capstone project (patterns, final deliverables)

Apply Factory, Decorator, and Dependency Injection on a real API project, profile performance with dotTrace, secure with JWT and middleware, unit test with xUnit, finalize a deployable portfolio on Azure, consolidate everything to shine in interviews or production.

Evaluation method

  • Daily interactive quizzes, graded final project, skills self-assessment, Qualiopi certification

Learning method

  • Active pedagogy through projects, hands-on exercises, real business cases, personalized feedback

Methods, materials and delivery

The Training C# Advanced - Master async and patterns for scalable apps 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# Advanced - Master async and patterns for scalable apps 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# Advanced - Master async and patterns for scalable apps 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.
