The 4DEVELOPERS Katowice 2019 conference
On October 21, 2019 I had the pleasure to participate in the Silesian edition of the 4DEVELOPERS conference in Katowice, which is the Silesian edition of the largest technology festival for programmers in Poland. The conference was addressed mainly to programmers who are familiar with Microsoft technologies. There were 32 lectures given by 32 speakers, and around 400 participants attended the entire event.
