Don't let this gap widen

Why this program matters

  • Without mastery of ReactiveUI, your reactive C# applications accumulate memory leaks and bottlenecks, causing unpredictable crashes and degraded user experience.

  • 70% of reactive development incidents stem from poor management of observables and commands, tripling debugging time.

  • A .NET team loses an average of 12 000 € per year on corrective maintenance and lost hours, eroding business competitiveness.

  • Your career and your company's risk obsolescence against fluid and scalable competitors – every month without advanced skills widens the gap irreversibly.

ReactiveUI training objectives

  • Acquire an advanced understanding of reactive design with ReactiveUI
  • Apply the MVVM pattern in designing reactive user interfaces
  • Effectively manage asynchronous data flows and complex user interactions
  • Implement unit tests on reactive views and ViewModels
  • Optimize the performance and maintainability of reactive applications in production

ReactiveUI curriculum: 3 modules over 3 days

Module 1 : Introduction to Reactive Design and ReactiveUI

History of reactive design, differences between Rx.NET and ReactiveUI, installation of the framework and its dependencies. Structuring a typical project with ReactiveUI, discovery of key concepts (Observables, Observers, Bindings). First project: displaying dynamic data.

Module 2 : Reactive MVVM Pattern and Navigation

In-depth exploration of the MVVM pattern in ReactiveUI: creating ViewModels, advanced use of ReactiveCommand, managing reactive navigation with RoutingState, advanced data binding (Binding, WhenAny, ToProperty). Multi-view scenarios and complex business logic.

Module 3 : Asynchronism, Testing, and Optimizations

Advanced management of asynchronism and event streams. Testing techniques (unit and integration) for ViewModels and reactive UI. Performance optimization, diagnostics and tools, best practices for long-term maintenance. Practical cases on a complete application.

How ReactiveUI skills are assessed

  • Daily practical exercises
  • Quiz to validate learning outcomes
  • Red thread project: building a mini-reactive application

How the ReactiveUI course is taught

  • Illustrated courses and guided demonstrations
  • Individual and group practical workshops
  • Access to a digital resource repository and course materials
  • Personalized feedback on the red thread project

Our method

How Learni guarantees the quality of your ReactiveUI training

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.
