What should you do?

You are creating an application that reads from a database.

You need to use different databases during the development phase and the testing phase by using conditional compilation techniques.

What should you do?
A . Configure the Define TRACE constant setting in Microsoft Visual Studio.
B . Specify the /define compiler option.
C . Run the Assembly Linker tool from the Windows Software Development Kit (Windows SDK).
D . Decorate the code by using the [assembly:AssemblyDelaySignAttribute(true)] attribute.

Answer: B

Explanation:

You can specify the compiler settings for your application in several ways:

* The property pages

* The command line

* #CONST (for Visual Basic) and #define (for C#)

Note: You can have either the Trace or Debug conditional attribute turned on for a build, or both, or neither. Thus, there are four types of build: Debug, Trace, both, or neither. Some release builds for production deployment might contain neither; most debugging builds contain both.

Incorrect answers:

Not A: TRACE is used to enable tracing. It is not used for conditional compilation.
