[sdeming6543]

Module/Lab: 10

Exercise: 03

Task: 02

Step: 03

Description of issue:
In the code block, on lines #15 & #18, the reference to "default" is missing the null-suppression operator "!". The previous code block in Exercise 2/Task 2/Step 3 does have the null-suppression operators included.

#15 should look like:
static ServiceBusClient client= default!;

#18 should look like:
static ServiceBusProcessor processor = default!;
