Microsoft is continuing its courtship of students, some as young as high school age, to bring new blood into the ranks of .NET developers and Microsoft platform users. Microsoft invited more than 150 college students to the MIX09 show here as well as more than 75 high school students. "We went to some of the top design schools in the country and we flew 153 college students here," he said. "And we decided we wanted to get some high school students here as well, so we flew in 77 high school students," said Abu-Hadba.
