I found this tool this morning, ieHTTPHeaders. This Internet Explorer plug-in shows all of the HTTP Headers on a page. Quite useful for those times when you need to see what headers your site is sending the client.
Last week, Microsoft announced Sandcastle which produces MSDN style documentation for your Visual Studio projects. Sandcastle is used internally to build the .Net Framework documentation. About the same time, Kevin Downs the creator of NDoc an open-source .Net documentation tool, announced that he will not be working on future versions of NDoc. It's kinda sad to see a good project go wrong but it just goes to show you how frail the open source movement is. It is difficult enough to manage a project team that's on your payroll. It's exponentially more difficult to do so when contributors are doing so...
