Property Value
true
to enable code analysis (/analyze
).
- Attributes
Examples
The following example demonstrates how to use the EnablePREfast and AdditionalOptions properties to set the /analyze:WX-
switch. (Both properties are required to do this.) Specifying /analyze:WX-
means that code analysis warnings will not be treated as errors when compiling with /WX
. For more information, see /analyze (Code Analysis).
