Windows Live Writer Plugin: Imtech MSDN Reference plugin
If you are a .NET developer and blog about your challenges using Windows Live Writer this plugin is definitely for you. What it does is it picks up the selected text and creates automatically a link to the right page at the on-line MSDN reference. The plugin works both with selected text but it allows you to type the object name in its dialog window as well.
The plugin has an installer, so it will be automatically added to your Live Writer plugins.
