Questions:

• How does the new operator work under the hood

Skipped topics/keywords:

• Boxing and unboxing

• Anonymous types:

  Using the new operator with object initialiser syntax. Avoids declaring types. Used frequently in LINQ queries

  var v = new { Amount = 108, Message = "Hello" };
  

• dynamic type

• await foreach

  • When a sequence is IEnumerable, you use foreach
  • When a sequence is IAsyncEnumerable, you use await foreach

• out, ref and in keywords

  • out: this method sets the value of the argument
  • in: this method doesn't modify the value of this argument
  • ref: this method may modify the value

  Write safe and efficient C# code

• yield return

• extension methods — you can extend types with further methods. Pretty cool
