Retracts a solution.
|Retract(DateTime)||Creates a timer job to retract the specified solution at a particular time.|
|Retract(DateTime, Collection<SPWebApplication>)||Creates a timer job to retract the specified solution from the specified web applications at a particular time.|
When a solution is retracted, all files for that solution are retracted, even if another solution points to the same file. This can be avoided by ensuring that each solution points to a unique set of files.
