This document provides instructions for iLab 1, which involves creating a basic user interface in C# that collects a user's name, age, and car's gas mileage. The lab has 5 steps: 1) Review the program design, 2) Construct the program methods, 3) Compile and test the program, 4) Take screenshots of the program output, and 5) Submit all files and screenshots in a zip file to the Dropbox. The program uses methods like DisplayApplicationInformation(), GetInput(), and TerminateApplication() to prompt the user for input and display output.
