Extension method resolution with nullable value type params

Question

public static class Extension
{
    public static void Test(this DateTime? dt)
    {
    }
}


void Main()
{
    var now = DateTime.Now;
    Extension.Test(now); //          


        

Answer 1

As Tim said nullable +1

Fix:

  public static class Extension
  {
    public static void Test(this DateTime? dt)
    {
    }
  }

  public class Program
  {
    private void Main()
    {
      DateTime? now = DateTime.Now;
      Extension.Test(now); 
      now.Test();  
   }
  }
