You are developing an application.
The application contains the following code segment (line numbers are included for reference only):

When you run the code, you receive the following error message: “Cannot implicitly convert type ‘object” to ‘int’.
An explicit conversion exists (are you missing a cast?).”
You need to ensure that the code can be compiled.

You are creating a console application named App1.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):

You need to ensure that the code validates the JSON string.
Which code should you insert at line 03?

HOTSPOT
You are developing an application that includes a Windows Communication Foundation (WCF) service. The
service includes a custom TraceSource object named ts and a method named DoWork. The application must
meet the following requirements:
Collect trace information when the DoWork() method executes.
Group all traces for a single execution of the DoWork() method as an activity that can be viewed in the WCF
Service Trace Viewer Tool.
You need to ensure that the application meets the requirements.How should you complete the relevant code? (To answer, select the correct code segment from each dropdown list in the answer area.)

HOTSPOT
You are developing an application in C#.
The application will display the temperature and the time at which the temperature was recorded. You have the
following method (line numbers are included for reference only):

You need to ensure that the message displayed in the lblMessage object shows the time formatted according to
the following requirements:
The time must be formatted as hour:minute AM/PM, for example 2:00 PM.
The date must be formatted as month/day/year, for example 04/21/2013.
The temperature must be formatted to have two decimal places, for example 23-45.
