You will now, per tradition, build a very simple command-line application — an executable program that writes the "Hello World" string. You will build three versions of this application, one in each of the Visual Studio .NET languages: Managed Extensions for C++, Visual Basic, and Visual C#.
Installing the sample files that accompany this tutorial places each of the three Hello World programs in a separate subdirectory (\vc, \cs, or \vb) below the InstallDirectory\Samples\Tutorials\PlatformIntroduction\HelloWorld directory. Each application uses a single source-code file and a batch command-line build file.
