Before to write your first C# program below points are worth to note

  1. C# is Case Sensitive.
  2. All statements and Expressions must end with a semicolon ( ; ).
  3. The program execution starts at the Main Method.
  4. Unlike JAVA, file name could be different from the class name.

01. Open your Visual Studio. ( In here i am using VS 2013).

02. From Start page click on the “ New Project ” or Go to menu “ File > New > Project “. you will get the ” New Project Window “.


03. Select “Console Application” as displays on above image under ” Templates > Visual C# > Windows from the Left hand side bar. Select a proper location for your project and click on “OK” button.

You have to consider about “Capitalization Rules“. There are rules we should follow when we are developing a software to meet Industry Standards. You can find read about Capitalization Rules from Microsoft MSDN. (click here).


04. Now you can start the writing your Hello World code in the program window. Once you wrote the complete program which i explained on ” Lesson 01 ” it will looks like below.

05. Now you can save the program and click on “ Start ” button or Menu ” Debug > Start Debugging ” to execute your first program.

06. Once your application executed you can see the output “ Hello World ! ” Print on a black screen like below.
