I think it would be easier to listen if you have basic thread knowledge. I'm a Java developer, but since the C# grammar is similar, I had no trouble understanding it! However, it doesn't explain the basics thoroughly for beginners, so I have to look it up here and there... I think it's better to look it up while studying than to just spoon-feed it to me, so it was okay for me. It gives examples using Microsoft .NET documents, and explains the basic operations of classes that require understanding. As someone who doesn't know much about C#, it felt like it suggested a way to look it up, so I liked it!
