Light Task
The Light task wraps light.exe, the WiX linker. It supports a variety of settings that are described in more detail below. To control these settings in your .wixproj file, you can create a PropertyGroup and specify the settings that you want to use for your build process. The following is a sample PropertyGroup that contains settings that will be used by the Light task:
<PropertyGroup> <LinkerTreatWarningsAsErrors>False</LinkerTreatWarningsAsErrors> <LinkerVerboseOutput>True</LinkerVerboseOutput> <SuppressIces>ICE18;ICE45;ICE82</SuppressIces> <SuppressSpecificWarnings>1111</SuppressSpecificWarnings> <TreatSpecificWarningsAsErrors>2222</TreatSpecificWarningsAsErrors> <WixVariables>Variable1=value1;Variable2=value2</WixVariables> </PropertyGroup>
The following table describes the common WiX MSBuild parameters that are applicable to the Light task.
