Can I close the program from the main designer?

Question

Can you exit the application before completing the constructor and upload the main form?

At startup, I have a loading screen that appears before the main form loads. The loading screen is displayed from the designer until the designer completes.

I am doing something similar with an exit screen using a variable between the main form and the exit screen. I have an application exit in the main form if the exit screen returns true.

Finally, should the entire thread / class / loading / configuring the program be started in the main constructor, or am I doing it wrong?

Update:

I mean after program.cs and in the static main

namespace app
{
 public partial class app1 : Form
 {
   public app1()
   {  
      InitializeComponent();
      // open loading screen
      // initialize vars
      // create objects
   }
 // form opens when app1() finishes

• Is the app1()right place to initialize everything?
• "" app1(), - , .
