C# – How to Fix this C# issue No test matches the given testcase filter `FullyQualifiedName =

I am new to C# and Selenium and I have pretty much made a number of scripts but there comes a problem when I make more than 1 method or more than 1 class single method and single class always runs good.

I have tried every possible solution on the internet and my self tried solution in which I made a new project and copied the main code other than class name, method name and namespace and pasted it onto new project it worked fine this is the same issue but I want to know what the problem really is.

These are the Four Classes:

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

using System.Threading.Tasks;

namespace SignUpPageAssignment
{

    public class SignUpDetails
    {
        public static string registerPageReDirect = "login_register";
        public static string signUpUserNameID = "username";
        public static string signUpPasswordID = "password";
        public static string confirmPasswordID = "re_password";
        public static string fullNameID = "full_name";
        public static string signUpEmailID = "email_add";
        public static string signUpUserName = "TouqeerABCDEFGHI";
        public static string signUpPassword = "Password@123";
        public static string confirmPassword = "Password@123";
        public static string fullName = "Touqeer Saleem";
        public static string email = "sabaloch67@gmail.com";
        public static string checkBox = "tnc_box";
        public static string captchaForm = "captcha-form";
        public static string signUpButton = "Submit";

    }
}

   {
       public static string loginUserNameID = "username";
       public static string loginPasswordID = "password";
       public static string loginUserName =   SignUpDetails.signUpUserName;
       public static string loginPassword = SignUpDetails.signUpPassword;
       public static string loginButton = "login";
       public static string redirectToLogin = "Click here to login";

   }

            driver.FindElement(By.Id(SignUpDetails.signUpButton)).Click();

            //SIGN UP END

            //LOGIN IN START

            driver.FindElement(By.LinkText(LoginDetails.redirectToLogin)).Click();
            driver.FindElement(By.Id(LoginDetails.loginUserNameID)).SendKeys(LoginDetails.loginUserName);
            driver.FindElement(By.Id(LoginDetails.loginPasswordID)).SendKeys(LoginDetails.loginPassword);
            driver.FindElement(By.Id(LoginDetails.loginButton)).Click();

            //LOGIN IN STOP

            //IWebElement result =     driver.FindElement(By.ClassName("reg_success"));


            //Assert.Equals("reg_success", result);

        }
