How do you use collection initializers to create a new dictionary?

Question

If you can do this in List

List<int> a = new List<int>() {
   2, 4, 6, 8, 10
};

how can you do the same thing in Dictionary?

Dictionary<int, bool> b = new Dictionary<int, bool>() {
   ?, ?, ?
};

You just wrap each key-value pair in curly brackets.
