How does the XmlSerializer work? What ACL permissions does a process using it require?

Purpose:

• Anybody that has worked extensively with either Web Services, APIs or Relational Mapping tools would have come across Serialization idiosyncrasies. Some may have written their own persistence frameworks or tried different serialization strategies to improve performance. This level of in depth understanding bodes well.

Potential Answer:
Creates a temporary assembly with the reader and writer type derived from the XmlSerialization equivalents in the .Net Framework. These methods do the actual serialization operation. ACL comes in with the writing of the temp assembly to the temp folder since it needs write and delete permissions to that folder.
