But that is the lesser problem. The question remains: How does .NET Runtime know which implementation to execute when you make a call to a virtual method on an object? We ask the same question about .NET Reflection, too. How does the GetType() method know the right type object to return when we call it on a reference to its base type? Such a confusion! This video dives into the structure of every instance of every reference type in .NET. You will learn about the type descriptor and the table of virtual methods - two fundamental traits of every object you instantiate. By understanding how method resolution works during run time, you will know everything about virtual methods in .NET and C# and any other object-oriented language, all the same. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⚡️RIGHT NOTICE: The Copyright Laws of the United States recognize a “fair use” of copyrighted content.
