What experience using WLW to write to an ASP.NET web site?

Question

I find that WLW is a very comfortable way to write web pages.

I'd like to experiment writing to a standard ASP.NET web site using it.

If anybody around here has experience doing that I'd appreciate a heads up on what you've found like:

1)  Metaweblog versus Atom API.

2)  Best code to start with.  (I'll start off using something open source, BSD or similar license.  On an internal web server.)

3)  Running it on .NET 3.5 and 4.  (I'd like to experiment with 4.)

4)  General observations, coding it, debugging, operating...

Thanks.

At the end of the day, in my view, WLW is the way to go for all comments, wiki's etc. on the web.  I'd love to get away from the flaky, underperforming, often unique but at least incredibly varied content editors we tend to see every day.

(Heck I'd even like to be writing this question in something like WLW, though this forum has a good editor, unlike many!  That way I get to keep a copy for my own notes.)
