WiX Toolset

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.

Parameter Description
BindInputPaths Optional string parameter.

Specifies a binder path that should be used to locate all files. This is equivalent to the -b <path> switch.
Named BindPaths are created by prefixing the 2-or-more-character bucket name followed by an equal sign ("=") to the supplied path.
BindFiles Optional boolean parameter.

Specifies that the tool should bind files into a .wixout file. This is only valid when the OutputAsXml parameter is also provided. This is equivalent to the -bf switch.
Pedantic Optional boolean parameter.

Specifies that the tool should display pedantic messages. This is equivalent to the -pedantic switch.
SuppressAllWarnings Optional boolean parameter.

Specifies that all warnings should be suppressed. This is equivalent to the -sw switch.
SuppressIntermediateFileVersionMatching Optional boolean parameter.

Specifies that the tool should suppress intermediate file version mismatch checking. This is equivalent to the -sv switch.
SuppressSchemaValidation Optional boolean parameter.

Specifies that schema validation of documents should be suppressed. This is equivalent to the -ss switch.
SuppressSpecificWarnings Optional string parameter.

Specifies that certain warnings should be suppressed. This is equivalent to the -sw[N] switch.
TreatSpecificWarningsAsErrors Optional string parameter.

Specifies that certain warnings should be treated as errors. This is equivalent to the -wx[N] switch.
TreatWarningsAsErrors Optional boolean parameter.

Specifies that all warnings should be treated as errors. This is equivalent to the -wx switch.
VerboseOutput Optional boolean parameter.

Specifies that the tool should provide verbose output. This is equivalent to the -v switch.
