Dissecting the Program Class

Beyond providing implementation code for an initial Form-derived type, Windows Application proj-

ect types also provide a static class (named Program) that defines your program’s entry point—Main():

static class Program

{

[STAThread]

static void Main()

{

Application.EnableVisualStyles();

Application.SetCompatibleTextRenderingDefault(false);

Application.Run(new MainWindow());

}

}

As expected, the Main() method invokes Application.Run(), as well as a few other calls on the

Application type to establish some basic rendering options. Last but not least, note that the Main()

method has been adorned with the [STAThread] attribute. This informs the runtime that if this

thread happens to create any classic COM objects (including legacy ActiveX UI controls) during its

lifetime, they are to be placed in a COM-maintained area termed the single-threaded apartment. In

a nutshell, this ensures that the COM objects are thread-safe, even if the author of a given COM

object did not explicitly include code to ensure this is the case.
