ASP.NET (C#) Question

EntityType ' ' has no key defined

So I have been following this tutorial on ASP.NET. I have created a Model and intend on generating a Controller with views, using Entity Framework. However I have been stuck on this error for nearly hours researching causes and its only 2 lines of code and I can't for the life of me understand how I am getting this error.

This is all the code I have written

Here we go:

You should to add the [KEY] attribute for your TaskID like this code:

public class Tasks
 public int TaskID {get;set;}
 public string taskStatus {get;set;}

Hope it helps;)
