C# 14 and .NET 10 Training

Description of the C# 14 and .NET 10 Training Course

This C# 14 and .NET 10 training course enables you to master the development of modern applications on the Microsoft platform. You will learn the fundamentals of the language, object-oriented programming and the .NET architecture while discovering new features designed to improve performance and productivity. The programme also covers ASP.NET Core, EF Core and essential development tools. Through practical workshops, you will develop a complete application applying best practices for maintainable code. Upon completion, you will be able to design robust and scalable solutions with C#.

Also discover our MAUI .NET Training Course – Develop Mobile and Desktop Applications with C#, our REST API – Create, Expose and Integrate Secure and Scalable Web Services, our Flutter 3 Training Course – Cross-Platform High-Performance App Development with Dart, our JMeter Performance Testing Training – Simulate, Measure and Optimise your Web Applications at Scale, our Load Testing Training – Simulate Real User Behaviour to Evaluate the Limits of your Applications and our IT Specifications Training Course – From Requirements to Project Specification.

It is possible to customise the training content to meet the needs of your professional project.

GOOD TO KNOW

This training course includes many exercises (60% practice) for better learning. Sessions are guaranteed from 1 registered participant (except in cases of force majeure). A preliminary interview takes place between the participant and/or a company representative to properly account for the participant’s profile (level, needs, professional context, challenges…).
Assessment: during the training, the trainer evaluates the pedagogical progress of participants through MCQs, role-play scenarios and practical exercises. Participants receive a certificate of skills validation at the end of the training.

Objectives of the C# 14 and .NET 10 Training Course

Upon completion of the training, the participant will be able to:

  • Understand the concepts, architecture and technologies of the .NET platform.
  • Master the syntax and features of the C# language.
  • Configure and use development tools such as Visual Studio for .NET projects.
  • Leverage the new features of C# 14, designed to improve productivity and code quality.
  • Design web, API or desktop applications thanks to improvements in ASP.NET Core and the .NET 10 ecosystem.

Prerequisites

  • Basic structured or object-oriented programming skills recommended.
  • Familiarity with a development environment.
  • Prior experience with a language such as Java, C++ or JavaScript is a plus.
  • Because each participant is unique, a personalised interview with our expert allows us to design a training course perfectly aligned with their objectives, level and professional challenges.

Target Audience

  • Developers wishing to create modern applications with C# and .NET.
  • Software engineers and technical consultants working in the Microsoft ecosystem.
  • IT professionals wanting to adopt the latest framework versions to improve performance and maintainability.

FAQ – C# 14 and .NET 10 Training

C# 14 introduces extension members (properties and operators on existing types), the field keyword inside auto-implemented properties, params collections improvements, partial constructors and events, null-conditional assignment, and enhanced unbound generic types. It targets .NET 10 and continues C#’s push toward expressiveness and performance. MFE-IT trains developers on C# 14 features through hands-on refactoring of existing C# codebases.

Yes, .NET 10 is a Long-Term Support release with three years of support, released by Microsoft in November 2025. LTS releases are recommended for production applications and enterprise migrations. The MFE-IT C# 14 / .NET 10 training covers the migration path from .NET 8 (the previous LTS) and identifies breaking changes you need to handle.

There is no longer a distinction in 2026: .NET Core was renamed to simply .NET starting with version 5 (2020), unifying the previously separate .NET Framework, .NET Core, and Xamarin platforms. .NET 10 is the current LTS in this unified line. The MFE-IT C# 14 / .NET 10 training clarifies the .NET versioning history and the modern unified runtime model for teams maintaining legacy code.

Upgrading from .NET 8 (current LTS) to .NET 10 (new LTS) is recommended for most projects: significant performance gains in JIT and GC, new C# 14 productivity features, longer support window, and continued framework innovation. Most .NET 8 applications upgrade with minimal code changes. Through MFE-IT’s hands-on approach, learners migrate a real .NET 8 project to .NET 10 during the training.
