There has never been official support from Microsoft for Doxygen?

If you use Visual Studio .NET have a look at Steve King's set of
addins. Greg Engelstad has written a perl script to parse a Visual
Studio .NET solution file (.sln) and run doxygen for each separate
project contained therein.
Jason Williams has written an Addin for Visual Studio 2005 & 2008
which is able to auto-generate doxygen (or DocXml) style comments from
most code elements (file, namespace, class, struct, enum, function,
etc). It parses C, C++, C# and Java code to produce fully formed
doxygen comments, and can update those comments if the code element is
changed, and word-wrap the descriptions to keep them tidy. It uses a
set of user-editable rules to provide automatic descriptions of
elements, parameters and return codes, minimizing the effort involved
in generating doc comments.
jgallardo has also written a Addin for Visual Studio that eases
browsing the documentation generated by doxygen.
An addin for Visual Studio 2005 called DoxyComment was created by
Troels Gram. It is designed to assist you in inserting context
sensitive comment blocks into C/C++ source files. DoxyComment also
comes with an xslt template that lets you generate documentation like
the MSDN library.
If you are using Microsoft's Developer Studio 6.0, an add-in called
DoxBar is available that can be used to run doxygen from within
Developer Studio and to search through the generated HTML help files.
Note: I do not have enough time to maintain DoxBar myself anymore, so
I moved DoxBar to sourceforge. Olivier Sannier has introduced a number
of improvements to DoxBar. If you too want to join the development
team, please register as a user at sourceforge and mail me your user
name.
Bernhard Nowara has written a profile editor, which is a
doxywizard-like tool for Windows. He also created an enhanced version
of DoxBar that includes his editor and some macros for Visual Studio
to ease the preparation of the source code for doxygen. These changed
have been merged into more recent version of doxygen by Olivier
Sannier.
FeinSoftware has released a development tool for Microsoft Visual
Studio .NET (Visual C++) called CommentMaker, which creates
customizable function header that developers can adjust to most
specific documentation requirements. By default it generates doxygen
compatible comments.
