System.Windows.MessageBox doesn't wait for user input before going poof!

Question

...and it makes no sense why. T-T

In my Application_Startup event handler I have code that looks kinda like this:

private void Applicati

Alexey is right, the splash screen closes the message box.

A simple way to avoid this is to use the native MessageBox function:

[DllImport("user32.dll", CharSet = CharSet.Unicode)]
public static extern int MessageBox(IntPtr hWnd, String text, String caption, uint type);

public static void Main()
{
   ...
   MessageBox(new IntPtr(0), "Hello World!", "MyApp", 0);
