I have the following function in C# and in JAVASCRIPT when I place a stop point (F9) on the function in c# it works normally, but the debugger No, he won’t stop, I’m doing something wrong?

I’m using Visual Studio 2017

 @functions{

        public string obterDado2()
        {
            string Validador = TipoPecaController.validar2;
            return Validador;
        }
        public string alterar()
        {
            TipoPecaController.validar2 = "";
            return TipoPecaController.validar2;
        }
    }

    <script type="text/javascript">
        var vd = "";

        window.onload = function() {
            debugger;
            vd = @obterDado2();
            debugger;
            if (vd == "True") {

                alertify.alert("Aviso", "Esse Tipo de Peça já existe, tente cadastrar um diferente", function () {
                    alertify.message('OK');
                });
                vd = @alterar();
            }
            else if (vd == "Trues") {
                    alertify.alert("Aviso", "Essa sigla já existe, tente cadastrar uma sigla diferente", function () {
                        alertify.message('OK');
                    });
                    vd = @alterar();
            }
        }
    </script>

Well, I’m a beginner and I didn’t know it was necessary the F12, I’ll test, thank you

This is for if you want to debug without ide.. I don’t know if that’s your case

I’d like it to go through the ide, but thanks, I’ll get to learn about debugging by the browser

What kind of VS project are you talking about?

I don’t know exactly understood the question, but I work with Asp.net

It seems to me Razor Pages, the question is whether you are talking about MVC, Razor Pages, Web Forms, Blazor or other structure.

Well, I don’t know if I’m going to answer this question correctly, as I said I’m a beginner, but it must be Web Forms, because I’m working with forms, I’m not in the company anymore, but I’m going to post the code all tomorrow when I get there

If you want to debug javascript by VS 2017 you have to use/navigate that page that it opens automatically when you press F5

Except for some points to be noted here, you are declaring your strings in javascript without using quotes...

The result of vd = @obterDado2(); would be vd = True; and not vd = "True";, see the correction.

@functions{

    public static class TipoPecaController
    {
        public static string validar2 { get; set; } = "True";
    }

    public string obterDado2()
    {
        string Validador = TipoPecaController.validar2;
        return Validador;
    }
    public string alterar()
    {
        TipoPecaController.validar2 = "";
        return TipoPecaController.validar2;
    }
}

<script type="text/javascript">
        var vd = "";

        window.onload = function() {

            vd = "@obterDado2()";

            if (vd == "True") {

                alertify.alert("Aviso", "Esse Tipo de Peça já existe, tente cadastrar um diferente", function () {
                    alertify.message('OK');
                });
                vd = "@alterar()";
            }
            else if (vd == "Trues") {
                    alertify.alert("Aviso", "Essa sigla já existe, tente cadastrar uma sigla diferente", function () {
                        alertify.message('OK');
                    });
                    vd = "@alterar()";
            }
        }
</script>

Then... the statement debugger, is for the browser only. Visual Studio will not pause execution at this point. To debug from the IDE just place a breakpoint where you want to stop...

... But you need to make sure that the debuggar JS functionality is enabled on Tools -> Options -> Debugging
