Good to know
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.

This training course is part of our Development Training Courses. Explore our other development trainings to design modern, performant and maintainable applications.

FAQ
What's new in C# 14?

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.

Is .NET 10 LTS?

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.

What is the difference between .NET and .NET Core?

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.

Should I upgrade from .NET 8 to .NET 10?

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.
