This is a common way for interviewers to start an interview for a software developer who needs to specialize in the .NET Framework. Show the interviewer your ability to utilize the .NET Framework effectively by describing what it is, when to use it and its main features. Try to show your practical knowledge of the system.
Example: “.NET is a Microsoft framework designed to help developers work with different coding languages. In simple terms, it’s a virtual machine that assists with the compilation, conversion and execution of code within a development framework. Using .NET, developers can create form- and web-based applications and services.”
