help with my code it does not want to compile

Code:

---

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


namespace GenericUse
{
    class Gen<T,U>
    {
        public T t;
        public U u;
       
        public Gen(T _t, U _u)
        {
            t = _t;
            u = _u;
        }
        static void Main()
        {
            Gen<string, string> ao = new Gen<string, string>("Hello,", "World");
            Console.WriteLine(ao.t + ao.u);
        }
    }
}

And your error messages are?

Don't just dump the code.

the error message is :GenericUse.exe does not contain a static 'Main' method suitable for an entry point

I would create a separate class for this:

Code:

---

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


namespace GenericUse
{
    class Gen<T,U>
    {
        public T t;
        public U u;
           
        public Gen(T _t, U _u)
        {
            t = _t;
            u = _u;
        }
    }

    public class Testing
    {
        static void Main()
        {
            Gen<string, string> ao = new Gen<string, string>("Hello,", "World");
            Console.WriteLine(ao.t + ao.u);
        }
    }
}

thanks, that worked :)

To address *why* this was needed, it's because a generic class isn't really a single class - it's a family of related classes. Gen<int,string>.Main() is a different function from Gen<string, string>.Main() which is a different function than Gen<int,int>.Main(), etc.

When you try to put the main method inside a generic, there isn't a way to know which specific class's Main() should be used as the entry point.
