Who should attend

This course is highly recommended for:

  • Software engineers (C#)
  • C# developers
  • C# .Net developers
  • Software developers


Participants must know how to name, declare, initialize, and assign values to variables within an application. They should have experience using arithmetic operators to perform arithmetic calculations involving one or more variables, relational operators to test the relationship between two variables or expressions and Logical operators to combine expressions that contain relational operators.
Participants need to have experience creating code syntax for simple programming statements using C# language keywords and recognize syntax errors using the Visual Studio IDE, simple branching structure using an IF statement, simple looping structure using a For statement to iterate through a data array and function that accepts arguments (parameters and returns a value of a specified type.

Additionally, they must have an understanding of how to use the Visual Studio IDE to locate simple logic errors, design and build a simple user interface using standard controls from the Visual Studio toolbox, connect to a SQL Server database and the basics of how to retrieve and store data, sort data in a loop and recognize the classes and methods used in a program
