C# 0 The Complete Reference

Compiling from the IDE

To compile the program using the Visual Studio IDE, first create a new Windows Application 

project. Do this by selecting File | New Project. Then select Windows Forms Application in 

the New Project dialog box. Call the project 

WinSkel

. Delete all C# source code files that 

were automatically created. Next, right-click on the WinSkel project name and select Add 

and then select New Item. From the Add New Item dialog box, select C# Code File, and 

name the file 

MyWinProject.cs

build the solution. To run the project, select Debug | Start Without Debugging.
