Lit Task

The Lit task wraps lit.exe, the WiX library creation tool. 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 Lit task:

<PropertyGroup>
    <LibTreatWarningsAsErrors>False</LibTreatWarningsAsErrors>
    <LibVerboseOutput>True</LibVerboseOutput>
    <SuppressSpecificWarnings>1111</SuppressSpecificWarnings>
    <TreatSpecificWarningsAsErrors>2222</TreatSpecificWarningsAsErrors>
</PropertyGroup>

The following table describes the common WiX MSBuild parameters that are applicable to the Lit task.
