描述

The note in the targets file that sets the variable says these optimizations are relevant for net4.6, we're beyond that so we might be able to use the Microsoft.IO redist ones instead.

  1. decouple FEATURE_LEGACY_GETCURRENTDIRECTORY and FEATURE_LEGACY_GETFULLPATH from net472
  2. conditionally compile FileUtilities with using Microsoft.IO
  3. don't compile the custom methods outside of net35 taskhost project

研究方向
Locate the targets file that defines FEATURE LEGACY GETCURRENTDIRECTORY and FEATURE LEGACY GETFULLPATH. Identify the FileUtilities class and the custom methods to be replaced with Microsoft.IO.Redist equivalents. Check the Microsoft.IO.Redist package for available methods. Propose changes to conditionally compile FileUtilities to use the Microsoft.IO namespace instead of the custom implementations.
