Module 1 Review of Visual C# Syntax

Module Overview Overview of Writing Application by Using Visual C# Data Types, Operators, and Expressions Visual C# Programming Language Constructs

Lesson 1: Overview of Writing Application by Using Visual C# What Is the .NET Framework? Key Features of Visual Studio 2012 Templates in Visual Studio 2012 Creating a .NET Framework Application Overview of XAML

What Is the .NET Framework?

Key Features of Visual Studio 2012

Templates in Visual Studio 2012

Creating a .NET Framework Application In Visual Studio, on the File menu, point to New, and then click Project. In the New Project dialog box, choose a template, location, name, and then click OK.

Overview of XAML

Lesson 2: Data Types, Operators, and Expressions What are Data Types? Expressions and Operators in Visual C# Declaring and Assigning Variables Accessing Type Members Casting Between Data Types Manipulating Strings

What are Data Types?

Expressions and Operators in Visual C# Example expressions: + operator / operator + and – operators + operator (string concatenation)

Declaring and Assigning Variables Declaring variables: Assigning variables: Implicitly typed variables: Instantiating object variables by using the new operator

Accessing Type Members Invoke instance members Example:

Casting Between Data Types Implicit conversion: Explicit conversion: System.Convert conversion:

Manipulating Strings Concatenating strings Validating strings

Lesson 3: Visual C# Programming Language Constructs Implementing Conditional Logic Implementing Iteration Logic Creating and Using Arrays Referencing Namespaces Using Breakpoints in Visual Studio 2012 Demonstration: Developing the Class Enrollment Application Lab

Implementing Conditional Logic if statements select statements

Implementing Iteration Logic for loop foreach loop while loop do loop

Creating and Using Arrays C# supports: Single-dimensional arrays Multidimensional arrays Jagged arrays Creating an array Accessing data in an array: By index In a loop

Referencing Namespaces Use namespaces to organize classes into a logically related hierarchy .NET Class Library includes: System.Windows System.Data System.Web Define your own namespaces: Use namespaces: Add reference to containing library Add using directive to code file

Using Breakpoints in Visual Studio 2012 Breakpoints enable you to view and modify the contents of variables: Immediate Window Autos, Locals, and Watch panes Debug menu and toolbar functions enable you to: Start and stop debugging Enter break mode Restart the application Step through code

Lab Scenario You are a Visual C# developer working for a software development company that is writing applications for The School of Fine Arts, an elementary school for gifted children. The school administrators require an application that they can use to enroll students in a class. The application must enable an administrator to add and remove students from classes, as well as to update the details of students. You have been asked to write the code that implements the business logic for the application. During the labs for the first two modules in this course, you will write code for this class enrollment application. When The School of Fine Arts ask you to extend the application functionality, you realize that you will need to test proof of concept and obtain client feedback before writing the final application, so in the lab for Module 3, you will begin developing a prototype application and continue with this until then end of Module 8. In the lab for Module 9, after gaining signoff for the final application, you will develop the user interface for the production version of the application, which you will work on for the remainder of the course.
