Marks the handle for releasing and freeing resources.
Assembly: mscorlib (in mscorlib.dll)
Calling the or Dispose method allows the resources to be freed. This might not happen immediately if other threads are using the same safe handle object, but will happen as soon as that is no longer the case. Although most classes that use the SafeHandle class do not need to provide a finalizer, this is sometimes necessary (for example, to flush out file buffers or to write some data back into memory). In this case, the class can provide a finalizer that is guaranteed to run before the SafeHandle critical finalizer runs.
