Why / How should I be building a (static?) constructor for this puzzle?

Hopefully my code snippets transfer to this post. I'm not sure what I missed, when learning constructors in C#. Any help is valued, as I'm trying to figure out how / why a static constructor is suggested in this scenario.
Thanks!

IUnaryOperation.cs 
namespace Treehouse.CodeChallenges
{
    interface IUnaryOperation
    {
        double Perform(double value);   
    }
}
Increment.cs 
namespace Treehouse.CodeChallenges
{
    abstract class Increment : IUnaryOperation 
    {
        public double Value;

        //static Increment()
        //{

        //}

        // double Perform(double value);
        public double Perform(double value)
        {
            return Value;
        }
    }
}

I can see two issues:

  • the "Increment" class should not be abstract
  • the instructions say, "The Perform method should increment the value passed in by one."

Not sure why I was thinking I needed an abstract class. Set it to public to fix. The “return value” was just trying to bypass that section, while troubleshooting. I was focused on resolving the increment class not having any parameters (or whatever the resulting prompt was). Thanks !!!!
