Q:

Accessing alternate data streams in files

On an NTFS file system, it is possible to have alternate data streams within a single file.  Is it possible to access this information in a fully managed way? 
EDIT: additionally, I want to read from the alternate stream in an existing file.  How is this achieved (using PInvoke if not possible using managed code only)? 
This question is similar, but is from early 2009 and the .Net answer uses PInvoke to write to a file, not read from it.  Has support for this been added since then (to .Net 4.0?)  that can do it without using PInvoke? 

A:

Unfortunately no, there is still no access via a managed .Net Framework API. 
Update
Here's a library\source for an ADS access wrapper:
