The type or namespace name 'List' could not be found in C#

Error Message:

The type or namespace name 'List<>' could not be found (are you missing a using directive or an assembly reference?)

Error Description:

using System;

namespace ConsoleApp1

{

    class Program

    {

        static void Main(string[] args)

        {

            List<int> objList = new List<int>();

        }

    }

}

Error Solution:

You need to add using System.Collections.Generic;

 Namespace to get List<int>

using System;

using System.Collections.Generic;

namespace ConsoleApp1

{

    class Program

    {

        static void Main(string[] args)

        {

            List<int> objList = new List<int>();

        }

    }

}

Output:

Program compiled successfully.
