Step-by-Step Solution
Solution:
Step 1: Understand nested collection initialization
Each dictionary value is a List, so you must create new List instances inside the dictionary initializer. Step 2: Check syntax correctness
var dict = new Dictionary{1, 2} }, { "b", new List {3, 4} } }; correctly uses nested initializers: dictionary with key-value pairs, where values are new List with their own initializers. Final Answer:
var dict = new Dictionary{1, 2} }, { "b", new List {3, 4} } }; Quick Check:
Nested collections need explicit new List[OK]
Quick Trick: Use 'new' for nested collections inside dictionary [OK]
Common Mistakes:
MISTAKES- Omitting 'new List
' for nested lists - Using parentheses or brackets incorrectly
- Trying to use colon syntax inside C# initializers
