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 |
| 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. |
