QUESTION 1
You create an assembly by using .NET Framework 3.5.
The assembly creates a new text file in the root of the C: drive. The assembly will be used in a Windows Presentation Foundation standalone application. The assembly will also be used in a Windows Presentation Foundation XAML Browser Application (XBAP).
The assembly contains the following code segment.
(Line numbers are included for reference only.)

01 public void Save()
02 {
03
04 FileStream stream = File.Create(“c:\newfile.txt”);
05 try
06 {
07 StreamWriter writer = new StreamWriter(stream);
08 try
09 {
10 writer.WriteLine(“Bew line in text file”);
11 }
12 finally
13 {
14 writer.Dispose();
15 }
16 }
17 finally
18 {
19 stream.Dispose();
20 }
21
22 }

You need to ensure that the assembly functions without propagating errors in both standalone and XBAP applications.
What should you do?

A. Configure the assembly to use the Nothing Permission set.
B. Configure the assembly to use the Partial Trust Permission set.
C. Demand the FileIOPermissionAccess.Write permission in line 03 and add an exception handler at line 21.

The application interrupts the users in their tasks by prompting them to look for updates. You need to ensure that the application automatically detects updates without blocking the users interaction with the application.
What should you do?

A. Call the ApplicationDeployment.CheckForUpdate() function from the startup routine of the application.
B. Add an expiration element to the deployment manifest file. Set the maximumAge attribute to 24 and the unit attribute to hour.
C. Add the beforeApplicationStartup element to the deployment manifest file.
Configure a schedule job to launch another instance of the application in the background once a day.
D. Add a System.Windows.Threading.DispatcherTimer object and the ApplicationDeployment.CheckForUpdateAsync() function to the code-behind file.
Set the Interval property of the System.Windows.Threading.DispatcherTimer object to 1 day.
