The purpose of this final paper is to show the development of object-oriented web application using the C # programming language in Visual Studio framework through a web application for managing the seminar papers. Theoretical part of the paper explains object-oriented programming, basic concepts of object-oriented programming, C # programming language and three-layer architecture consisting of Model, View and Controller (MVC). All data and information contained in the theoretical part are collected through secondary research and synthesis methods. The second part of the application explains the process of developing the web application and the code sections are displayed. During development of application thirteen models, thirteen ViewModels and ten controllers (Controllers) were used and they are the key to the application's functioning. Views of user interfaces are with built with HTML code and CSS that serve to design the application. After that, the functionality or purpose of the application is displayed. The application is intended for professors and students to reduce the work associated with the seminar paper. The main advantage of this application is that all the jobs for managing seminar paper are united in one place and that all the actions on the application can be done with a few clicks. One of the disadvantages is the inability to load documents with the seminar papers on the application. The main issue that remains open is the modernization and virtualization of all parts of education at higher education institutions and universities.
