How to change the startup form in a project?

I made a test project and added in a couple files.

Now I want the startup file to be say form2.cs and not form1.cs.

I'm having a devil of a time finding the setting that tells the project which file to load 1st when being executed.

Can someone point it out to me please?

WinForms

in your Program.cs, which will look something like this

static class Program
{
   /// <summary>
   /// The main entry point for the application.
   /// </summary>
   [STAThread]
   static void Main()
   {
      Application.EnableVisualStyles();
      Application.SetCompatibleTextRenderingDefault(false);
      Application.Run(new Form1());
   }
}

Change 

Application.Run(new Form1());

To

Application.Run(new Form2());

WPF

To change startup window update App.xaml by changing Application.StartupUri

Application.StartupUri Property

Gets or sets a UI that is automatically shown when an application starts

Remarks

Typically, you set the StartupUri property declaratively in XAML. However, you can set StartupUri programmatically, such as from a Startup event handler, which is useful if for applications that can only load the necessary UI resources at run time. For example, an application might wait until run time to load its resources if the name of the UI resource is stored in a configuration file.

I saw a xaml file so I assume that thi is a WPF app. In that case you need to change this in App.xaml

<Application x:Class="WpfApp1.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:WpfApp1"
         StartupUri="MainWindow.xaml">
<Application.Resources>

</Application.Resources>

Change StartupUri to the one that you want.

I hope this will help.

You are looking for way of changing startup form.

As stated here: Changing startup form in C#

Look in Program.cs in the Main function for something like this

Application.Run(new MyForm()); Change MyForm to your other form.
