At this point, we are planning .NET Developerdays 2021 as in-person event!

What is .NET DeveloperDays


.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.

Important information

Due to the current pandemic situation, we are not sure if the conference will be possible in its usual in-person form. Therefore, depending on the regulations in place at the time of the event, it will take one of the following forms:
– if the in-person events are allowed: as a in-person
– if the in-person events are not allowed: as a fully virtual conference (similar to our 2020 event)
Please refer to our decision tree diagram for details.
