24,815 PointsYour matchingBirds variable should have two elements - but it actually has 3
Create a variable named matchingBirds and assign it a LINQ query on the birds variable that have the same Color property as the mysteryBird object. In the query, return an anonymous type with a property named BirdName and assign to it the Name property of the birds. Not sure what I am doing wrong.
I can not not figure out the syntax for this challenge!
var birds = new[]
{
new { Name = "Pelican", Color = "White" },
new { Name = "Swan", Color = "White" },
new { Name = "Crow", Color = "Black" }
};
var mysteryBird = new { Color = "White", Sightings = 3 };
var matchingBirds = from b in birds where mysteryBird.Color == "White" select new { BirdName = b.Name};

231,198 PointsYour syntax is good, but you're comparing the wrong values.
You have this conditional expression: where mysteryBird.Color == "White"
ā but the mystery bird's color is always white.
What the challenge asks for are the "birds ... that have the same Color property as the mysteryBird". That would be:
Ā Ā where b.Color == mysteryBird.Color
