MSBuild compares what is in FileWrites with the Outputs of the target
and any file that exists in FileWrites but *doesn't* exist in Outputs
gets deleted with the assumption that it is no longer needed via the
IncrementalClean MSBuild target.
Since these tasks cannot know what the outputs will be until the task
is run, we cannot use FileWrites.

from IL, but will be needed at runtime to correctly serialize (or
deserialize) objects.
* OnDeserializedAttribute
* OnDeserializingAttribute
* OnSerializedAttribute
* OnSerializingAttribute
This, along with aad627c5e8ddf15397c87fa2d3e18b54f929c927, fixed bug
40574. The later part will have new unit tests in XI.
