I try .net6 for the first time and i got an error ask me to provide return value regardless that i already provided one.

That only returns if the condition in the if statement is true. You need a return regardless of conditions.

No, because now the for loop will only run ones.

static int Search(int[] nums, int target)
{
  for(int i = 0; i < nums.Length; i++)
  {
    if (nums[i] == target)
      return i;
  }

  return -1;
}

static int Search(int[] nums, int target)
{
  for(int i = 0; i < nums.Length; i++)
  {
    if (nums[i] == target)
      return i;
  }

  return -1;
}

there is no guarantee that the code will enter the for loop

You need to add a return at the very end where it is not based on any conditions or anything. Sort of like fallback if everything else fails/doesn't run at least that will return.

also, .IndexOf exists :)

[1, 5, 7, 3, 12, 54].IndexOf(7); => 2

[1, 5, 7, 3, 12, 54].IndexOf(7); => 2
