VCCLCompilerTool.EnablePREfast Property

Definition

Gets or sets whether Native Code Analysis is enabled.

[System.Runtime.InteropServices.DispId(89)]
[get: System.Runtime.InteropServices.DispId(89)]
[set: System.Runtime.InteropServices.DispId(89)]
public bool EnablePREfast { get; set; }
Property Value

true to enable code analysis (/analyze).

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).
