Choose which window to open

[PlausiblyDamp]

So the MainForm.cs is the main file that opens. I've created another form Splash.cs, how do i get the Splash.cs to show before the MainForm loads. Doesn't matter if its in the background showing, just want to see the Splash.cs first.

I thought I could choose that open in the properties, but I can't find it.

So I presume its a piece of code probably related to window and show or something.

Any advice please?

Thanks

Normally you will find this in the Main method of your application, usually in Program.cs
