'error CS0103: The name 'UserContext' does not exist in the current context

I have inherited an ASP.Net 2.0 Web application built in VS 2005 and am trying to port it to VS 2017 and Framework 4.8. In a class that is trying to determine if the user is authorized to access the system it is erroring with "error CS0103: The name 'UserContext' does not exist in the current context" and when I am in the debug mode and evaluating the line where the error is occurring the UserContext essentially does not know who the user is (me in this case) at all. I assume that it is something wrong with the web.config file settings or something. Am I missing something in the web.config file perhaps? Do I need to change the use of the UserContext to something else for Framework 4.0?

using System;
using CoreServices; //CoreServices is a webservice


.... partial class code where authentication check is being called ....

public static void InitUserContext()
{
    if (UserContext.Current.Initialized)
        return;

    UserDTO user = null;
    CoreService proxy = new CoreService();

    DataContractUserDTO result = proxy.UserByLogin(UserContext.Current.GetLogin()); /// Code is erroring here

    if (!result.Success)
    {
        if (result.CriticalError)
            GotoErrorPage(result.ErrorMessage);

        user = new UserDTO();
        user.FullName = UserContext.Current.GetFullName();
        user.Login = UserContext.Current.GetLogin();

        DataContractOfFLRTUserDTO userResult = proxy.CreateUser(user);

        if (!userResult.Success)
        {
            if (userResult.CriticalError)
                GotoErrorPage(userResult.ErrorMessage);
        }

        user = userResult.Data[0];

    }
    else
        user = result.Data[0];

    string roles = (string.IsNullOrEmpty(user.Roles) ? "" : user.Roles);

    UserContext.Current.InitContext(user.UserID.Value, user.FullName, roles);
}

After further investigation this an issue much deeper in the solution with some flawed logic in the code.
