In this challenge : https://teamtreehouse.com/library/querying-with-linq/now-youre-querying/selecting-projecting-and-anonymous-types-2 on task 2 of 2 it is taking a long time to check my work any solutions?

The instructions say "Create a variable named matchingBirds and assign it a LINQ query ...". So you'll need to create a LINQ expression using the "birds" variable.
Then it says, "In the query, return an anonymous type with a property named BirdName and assign to it the Name property of the birds.". So you had the right idea about creating the anonymous object, but instead of the "Color" property you'll assign 'BirdName" with the "Name" property. And this will be done for each matching bird using the LINQ query. The final result will be a collection of anonymous objects instead of just one.
Another hint: when constructing my LINQ query I used both "Where" and "Select".

231,248 PointsHere's a few more hints:
- you won't be adding to "birds", but using it to select items to assign to "matchingBirds"
- the instructions ask for you to use a LINQ query to do this
- the LINQ methods of "Where" and "Select" may be useful (or the "query syntax" equivalents)
- the "BirdName" property should be a Name, not a Color
- "mysteryBird" will be used only for comparing, not for assigning
- as a last resort, look at answers to other questions about this same challenge

Courses Plus Student 13,331 PointsThis is actually a bug that I reported to treehouse support. Every time in challenge 2 of 2 the compiler freezes.
Steven Parker
231,248 PointsIt could also be a side-effect of the code. Show your code here and we can check it.

Courses Plus Student 13,331 PointsSure :
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 = new {BirdName = mysteryBird.Color};

Courses Plus Student 13,331 PointsWhen there is an error it gives me a compiler message though when there isn't the challenge freezes then after a short period of time asks me to reload the challenge then the whole thing starts again (This all happens in challenge 2).

Courses Plus Student 13,331 PointsThis has been reported to treehouse support though they do not have an issue on their end and I did try it on different devices though it is the same story.

Courses Plus Student 13,331 PointsI re watched the video though I don't know where I'm going with this :
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 = new {BirdName = mysteryBird.Color};
birds.Add(matchingBirds);

Tojo Alex
Courses Plus Student 13,331 PointsBefore you answered again I did a few more changes :
var birds = new[]
{
new { Name = "Pelican", Color = "White" },
new { Name = "Swan", Color = "White" },
new { Name = "Crow", Color = "Black" }
};
var mysteryBird = new { Name = "Bird" , Color = "White", Sightings = 3 };
var matchingBirds = birds.Where(b => ???).Select(b => ???);
