We invite you to the two-day free conference WUG Days 2026, where leading Czech experts in Microsoft technologies will speak in person and, in 40 professional, practically oriented lectures, they will introduce you to both new developments for administrators and developers, as well as best practices associated with currently used technologies. The conference will be held in person only, we are not planning a hybrid format with streaming. Our goal is to build a community and create a space where experts can meet their colleagues in person, share experiences and make new contacts. We consider these personal meetings to be one of the greatest benefits of the conference. Moreover, high-quality streaming involves a lot of extra work and its only added value compared to recordings is the ability to ask questions in the chat, which the participants of our online lectures did not use much. We therefore decided to go the route of publishing recordings of selected lectures. If you want to actively participate in discussions and meet other experts in the field, we would be happy to welcome you in person to the conference.
