causes all new .NET objects returned to the Wolfram Language during the evaluation of expr to be released when expr finishes.


  • To use NETBlock, you first need to load .NET/Link using Needs["NETLink`"].
  • It is an error to refer to a released object.
  • NETBlock only affects new objects, not additional references to ones that have previously been seen.
  • NETBlock is a way to mark a set of objects as temporary so they can be automatically cleaned up on both the Wolfram Language and .NET sides.
