I am a student who wants to get a job as a developer this year. I couldn't figure out what to do because there were no lectures on WPF, but I came across it by chance, and I am grateful that you made such a great lecture beyond my expectations. Also, since there is no limit to the number of times you can take the course, I was able to understand the parts that I didn't understand well the first time by listening to them multiple times, and I think my skills have improved. Thank you.
