Lesson 12. Basic Concepts of .NET

Objective: Provides a systematic understanding of the fundamental principles of building modern software platforms and the features of data management in the runtime environment. At the lowest level of Knowledge/Remembering, the student must identify key historical stages in the development of programming languages, such as the emergence of the C language in 1972 and the .NET platform in 2002, as well as name the two main types of types in the CTS system - value types and reference types. The Understanding level requires the student to explain the prerequisites for the emergence of object-oriented programming due to the limitations of the C language in working with large projects and to formulate the fundamental difference in the behavior of data when copying: creating a duplicate value for value types versus creating an additional reference to the same object in memory for reference types. At the Applying level, the student must demonstrate an understanding of memory mechanisms by applying object rules to predict changes in the program, for example, realizing that changing a property through one reference variable will affect all other references to the same object. The fourth level, Analyzing, requires the student to analyze the impact of the advent of the Internet on the transformation of programming languages ​​into tools for creating distributed Internet applications and to distinguish the logical structure of data types (numbers, characters, boolean types) and their physical organization in the CTS system. At the Evaluating level, it is necessary to justify the advantages of using a unified type system (CTS) to ensure interoperability between different programming languages ​​within the same platform and to criticize the disadvantages of manual memory management and pointers inherent in the C language compared to the safety of managed code in .NET. At the highest level of Creating, the student must develop (plan) the optimal data structure for a specific application, rationally combining value types for simple calculations and reference types for complex objects, as well as design a conceptual diagram of a portable software module that takes advantage of the .NET architecture to work in different operating environments.
