One of the first C# challenges

I'm showing error cs1605 and its detected on line (9,22). As you can see my code ends on line 3 and I can't even access the 9th line. Could somebody help me past this issue?

CodeChallenge.cs
Console.ReadLine();
string firstName;
Console.WriteLine(firstName);

You forgot to initialize your variable.

You didn't say which task you were on, but task 1 says, "Declare a variable named firstName and initialize it to the string returned from a call to Console.ReadLine()."

You do have a call to ReadLine, but you didn't assign the return value to anything. You should have something more like this for task 1:

string firstName = Console.ReadLine();

Apparently the challenge let your isolated call slip by task 1, you might want to report this as a bug to Support.

I was worried that that could have been the case with getting past the first part and not being able to complete the second afterwards. Thank you.

On the video Receiving Input about minute 3:44 shows the example explaining the answer for task 1

string entry = System.Console.ReadLine();
