Class always tries to open in Design View, not Code View

Question

I have a class named Print.cs that always stubbornly opens in Design View, when I need to see its Code View (F7). It also has a different icon to the rest of my classes in the Solution Explorer.

I've looked in the Properties and can't see anything relevant. I've also tried deleting and re-creating the class, but the icon comes back.

How can I force Print.cs to always open in Code View?

NB: disregard the green squiggly line, it's just a warning that unreachable code was detected.

Answer 1

Taken from the suggestions from @LarsTech and @OrkunBekar, since neither posted this as an answer - this works:

[System.ComponentModel.DesignerCategory("Code")]

Added between the namespace and the class, e.g.

using System;
using System.Collections.Generic;
...

namespace POS
{

    [System.ComponentModel.DesignerCategory("Code")]

    public class Print : PrintDocument
    {
        ...
    }
}

Answer 2

Try right click on the file -> Open With -> CSharp Editor (remember to set it as default).

Answer 3

Funny enough, it was totally other thing in my case. If the filename equal (=) to the first class in it, then Visual Studio decides it is a simple C# file. If you have 2 classes and the first is not equal to the file name, then the solution icon changes and default editor is designer.

Answer 4

I don't know if you have same conditions in that link but opening your class in notepad, changing codes, replacing file then building the solution again may fix the problem.
