Syntax Highlighter v0.2 has been released along with source code at Codeplex. This is an update to my original Windows Live Writer plugin which can be found at Windows Live Writer Syntax Highlighter.
As you might have noticed some of the features such as auto link detection, collapse, gutter (line numbering), toolbar, wrap lines and starting line number have been added.
