What are the ways to deploy an assembly?
MSI installer

CAB archive

XCOPY command
What is the .NET datatype that allows the retrieval of data by a unique key?
Can you change the value of a variable while debugging a C# application?
Yes, in Visual Studio use the Immediate window
How can you sort the elements of a the array in descending order?
By calling Sort() and then Reverse() methods
What are delegates?
A delegate defines a reference type that can be used to encapsulate a method with a specific signature. A delegate instance encapsulates a static or an instance method.

Delegates are roughly similar to function pointers in C++ however, delegates are type-safe and secure.
What is the CLR
Common Language Runtime
Common Language Runtime

the virtual machine component of the .net framework responsible for managing the execution of .net programs.
Functions of the CLR
compiled code (CIL) is converted into machine instructions that are then executed by the computer's CPU. additionally:

memory management
type safety
exception handling
garbage collection
thread management
Common Intermediate Language

.net compatible languages compile to a second platform-neutral language called CIL

The CLR compiles CIL to machine-readable code that can be executed on the current platform
virtual machine (VM)
a software implementation of a machine (i.e.: a computer) that executes programs like a physical machine.
what is a constructor?
the method of a class that is called when an object of that class is created.

the constructor initializes class parameters and has the same name as the class
what is a destructor?
deletes an object of the class from memory

gets called:
1. when the object is explicitly deleted by the code you write
2. when the object passes out of scope (i.e.: when the program exits a function)
how are methods overloaded in C#?
by specifying different numbers or types of parameters in the method definition

overloading allows flexibility with different types of data input
what is encapsulation?
combining function definitions and data together into a class
why use encapsulation?
to separate parts of the code from the rest of the program

allows the private data of an object to be hidden from the rest of the program

also allows classes to be reused in other programs
what is the difference between a class and a struct?
classes are passed by reference - structs are passed by value

classes can be inherited - structs cannot

structs generally give better performance as they are stored on the stack rather than the heap
