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.
