VCProjectConfigurationProperties.WholeProgramOptimization Property

Enables cross-module optimizations by delaying code generation to link time. Exposes the functionality of the compiler's /GL (Whole Program Optimization) option.

Namespace:  Microsoft.VisualStudio.VCProject
Assembly:  Microsoft.VisualStudio.VCProject (in Microsoft.VisualStudio.VCProject.dll)

WholeProgramOptimizationTypes WholeProgramOptimization { get; set; }

It is better to set the VCConfiguration object's WholeProgramOptimization property rather than to set the compiler property of the same name and the linker's LinkTimeCodeGeneration property.

The compiler's version of this property and the linker's LinkTimeCodeGeneration property are not available via the property pages.

See How to: Compile Example Code for Project Model Extensibility for information on how to compile and run this sample.

[Visual Basic]

The following example code modifies the VCConfiguration object's WholeProgramOptimization property in the development environment:

' add reference to Microsoft.VisualStudio.VCProjectEngine
Imports EnvDTE
Imports Microsoft.VisualStudio.VCProjectEngine

Public Module Module1
    Sub Test()
        Dim Test As Boolean
        Dim prj As VCProject
        Dim cfgs As IVCCollection
        Dim cfg As VCConfiguration
        Dim MyDbg As VCDebugSettings
        prj = DTE.Solution.Projects.Item(1).Object
        cfgs = prj.Configurations
        cfg = cfgs.Item(1)
        cfg.WholeProgramOptimization = True
    End Sub
End Module
