Join us for another great event on October 20-21, 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 to 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.

We are looking for seasoned speakers with highly technical sessions - this audience is demanding and unforgiving, so please make sure you do not inflate your session level. 300 and 400 level sessions are most desired, and we would be happy to consider "500" level. Very few 200 level sessions are accepted to this event.

We also have limited opportunities for 1-day pre-con and both 1-day and 2-day post-cons - if interested, please inquire about the details.

PRE-CONS: 19 October 2026
POST-CONS: 22-23 October 2026 (two day post-cons!)

We look forward to seeing you in Warsaw!

We cover return airfare and hotel for accepted speakers.
