MSBuild task reference
Tasks provide the code that runs during the build process. The tasks in the following list are included with MSBuild. When Visual C++ is installed, additional tasks are available that are used to build Visual C++ projects. For more information, see Visual C++ tasks.
In addition to the parameters listed in the topics in this section, each task also has the following parameters:
||Optional parameter. Can contain one of the following values:
- WarnAndContinue or true. When a task fails, subsequent tasks in the Target element and the build continue to execute, and all errors from the task are treated as warnings.
- ErrorAndContinue. When a task fails, subsequent tasks in the
