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.

The following table describes the parameters that are specific to the Lit task.

Parameter	Description
LibAdditionalOptions	Optional string parameter. Specifies additional command line parameters to append when calling lit.exe.
LibBindFiles	Optional boolean parameter. Specifies that the library creation 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 in lit.exe.
LibPedantic	Optional boolean parameter. Specifies that the library creation tool should display pedantic messages. This is equivalent to the -pedantic switch in lit.exe.
LibSuppressAllWarnings	Optional boolean parameter. Specifies that all library creation tool warnings should be suppressed. This is equivalent to the -sw switch in lit.exe.
LibSuppressIntermediateFileVersionMatching	Optional boolean parameter. Specifies that the library creation tool should suppress intermediate file version mismatch checking. This is equivalent to the -sv switch in lit.exe.
LibSuppressSchemaValidation	Optional boolean parameter. Specifies that the library creation tool should suppress schema validation of documents. This is equivalent to the -ss switch in lit.exe.
LibSuppressSpecificWarnings	Optional string parameter. Specifies that certain library creation tool warnings should be suppressed. This is equivalent to the -sw[N] switch in lit.exe.
LibTreatSpecificWarningsAsErrors	Optional string parameter. Specifies that certain library creation tool warnings should be treated as errors. This is equivalent to the -wx[N] switch in lit.exe.
LibTreatWarningsAsErrors	Optional boolean parameter. Specifies that all library creation tool warnings should be treated as errors. This is equivalent to the -wx switch in lit.exe.
LibVerboseOutput	Optional boolean parameter. Specifies that the library creation tool should provide verbose output. This is equivalent to the -v switch in lit.exe.
LinkerBindInputPaths	Optional string parameter. Specifies a binder path that the library creation tool should use to locate all files. This is equivalent to the -b <path> switch in lit.exe. Named BindPaths are created by prefixing the 2-or-more-character bucket name followed by an equal sign ("=") to the supplied path.
