WEBSERVICE ASP.NET Method not found

Question

I have a problem in a webservice that I created and I tried several adjustment options and could not solve.

I have the list of Methods available according to the image below

When I select the VAPS method the form to fill the fields appears correctly and fill and send works correctly.

The url that must be built to be invoked by GET must have the following format according to the documentation.

But when running this url I get the following message

All other methods are functional, the method problem not found occurs only with this one which is a new implementation, I believe there is something in the project that has not been updated.

Someone has already been through this and would have a solution?

I’ve restarted Machine, ISS, Visual Studio, changed input parameters, return type and none of it worked.

<WebMethod()>
    Public Function VAPS(CodTransacao As String, Email As String, Cod_Prod As Integer) As Boolean
        Dim cn As New MySqlConnection
        Dim sql As String

        Try
            sql = "SELECT * FROM TBL_CONCLUDED WHERE COD_PROD=@CodProd AND COD_TRANS=@CodTrans AND email=@email"

            Dim cmd = New MySqlCommand(sql, cn)

            cmd.Parameters.AddWithValue("@CodProd", Cod_Prod)
            cmd.Parameters.AddWithValue("@CodTrans", CodTransacao)
            cmd.Parameters.AddWithValue("@email", Email)

            cn.ConnectionString = ConfigurationManager.AppSettings("StrConn")

            Dim DA As New MySqlDataAdapter(cmd)
            Dim dt As New Data.DataTable

            cn.Open()

            DA.Fill(dt)

            MsgBox(dt.Rows.Count)

            If dt.Rows.Count > 0 Then
                Return True
            Else
                Return False
            End If

        Catch ex As Exception
            'MsgBox(ex.ToString)
            Return False
        End Try

        cn.Close()

    End Function

Good afternoon.

It’s hard to opine without seeing the code, but the first thing I would do is force a [Httpget] into your web method. Example:

[HTTPGet]
public string VAPS()
{
   ...
}

Have you tried that?
