Course objectives

The objective of the course is to introduce students to Windows Forms, WPF, and MAUI technologies, event-driven programming, data binding, and user interface design. In addition, students will master data management methods, including database management (Entity Framework Core, ADO.NET, LINQ) and data storage in various formats (JSON, XML). Furthermore, the course aims to develop students' problem-solving and application development skills through practical assignments and project work.

Autonomy and responsibilities

- He/she feels responsible for IT systems analysis, development and operation, both individually and as part of a team.

Requirements, evaluation and grading

Mid-term study requirements

The requirements and assignments to be completed during the semester are: - Theoretical quiz (in the form of a Moodle quiz during lab class), which will be worth 40 points. The minimum requirement is 20 points. - The practical part is worth 60 points, of which the minimum requirement is 30 points. The specific task will be defined by the instructor. Here, the students, working in teams of two or three, have to develop a WPF or MAUI application using database management. The application must implement CRUD functionality. The database manager must be MS SQL Server Express. - Students may earn additional points by completing assignments given by the instructor.

Generative AI usage

Use of GAI tools is permitted in a limited manner (e.g., for literature search support or specific tools). In this case, the course instructor is responsible for defining where and how GAI tools may be used in assignments. The course description must specify in detail how GAI tools may be used during the course.

Study aids, laboratory background

Recommended literature, outline of the lecture, programmes written in the exercises, a guide to the development environments. Each student will be provided with separate computer access for the exercises. 1. Required Visual Studio components - .NET desktop development workload - .NET Multi-platform App UI development workload - Individual components: SQL Server Express LocalDB, Class Designer 2. Additional software required - SQL Server Management Studio (SSMS) - Devart Entity Developer Express
