Selecting a Class In C#

[Mark-Phillipson]

In Visual Studio code unable to select a class in C#

Error Message: could not find containing class

Example Code:

public class Messages
{
    public string SendMessage(string message)
    {
        return message;
    }

}
SendMessage("testing")

Note it works perfectly well when there is a namespace:

namespace PacktexWebApp.Controllers
{
    public class Messages
    {
        public string SendMessage(string message)
        {
            return message;
        }

    }
    SendMessage("testing")
}
