What is the procedure here when the program won't take the correct answer?
public class Polygon
{
public int NumSides { get; private set; }
public Polygon(int numSides)
{
NumSides = numSides;
}
}
class Square : Polygon
{
public double SideLength { get; private set; }
public double Area { get => SideLength * SideLength; }
public Square(double sideLength) : base(4)
{
SideLength = sideLength;
}
}
namespace Treehouse.CodeChallenges
{
class Square : Polygon
{
public double SideLength { get; private set; }
public double Area { get => SideLength * SideLength; }
public Square(double sideLength) : base(4)
{
SideLength = sideLength;
}
public void Scale(double factor)
{
SideLength *= factor;
}
}
}
namespace Treehouse.CodeChallenges
{
class Polygon
{
public int NumSides { get; private set; }
public Polygon(int numSides)
{
NumSides = numSides;
}
}
}

4,771 PointsThe program is not taking the correct answer for this exercise: public double Area { get => SideLength * SideLength; } What is the procedure here ?

Treehouse TeacherHi there, Robert Stewart! You're very close! I'd encourage you to visit the preceding video and watch around the 1:54 mark. You have an extraneous get and some extra curly braces. Here is the C# documentation for expression body members for properties.
public double Area => SideLength * SideLength;
Hope this helps!

8,325 PointsYeah Thank you for the answer Jennifer Nordell, however it still bothers me that it took me 2 hours of rewatching the video and some previous ones to get to the answer. The instructions are not clear enough to guide one to the syntax that one is supposed to write and neither are the suggestions that the page makes when you have tried a wrong attempt, some of these suggestions talka about declaring the property inside Square and then it simply doesnt help much more in how one is supposed to calculate the square, since we cant use anything else like a Math.Pow function etc...
This whole C# course beginner course has just been a horrible experience, very little guidance, unclear project that you chose for us to work on, and stupidly organized order of things to learn. You are teaching us about error messages before having gone through various functions, training us how to write proper property and method syntax etc.
Sorry but after spending days on this one little course (and having ZOOMED through the Javascript one in less then a day and remembering almost everything) I had to voice my concerns, hope you take them to heart and don't just ignore this.

4,771 PointsThis is all fixed. I was just not used to the way the editor works with the course. I have it down now sorry about the terse comment I was just worried at the time that I was stuck in the course. Using the Team TreehouseCommunity supplies you with plenty of feedback for any troubles that you might have.
