About .NET DeveloperDays 2026
.NET DeveloperDays is the biggest event in Central and Eastern Europe dedicated exclusively to application development on the .NET platform. It is designed for architects, developers, testers, and project managers using .NET in their work, and for those who want to improve their knowledge and skills in this field. The conference content is 100% English, making it easy for the international audience to attend.
Event format
The conference will be held in hybrid mode:
- for people registered for an in-person participation – at the venue
- for those who registered for an online participation – remotely
The pre-cons and post-cons will be carried out in an in-person format only.
We are going to organize one-day pre-cons (October 20) and two-day post-cons (October 23-24).
