Deploying a VSTO Click Once Add-in - don't forget your MIME Types!

I just wanted to make a note of this for future reference and to help any one that might be struggling with this in the future:

I have just created a simple Excel 2007 office add-in and I wanted to deploy it to a local server on my intranet and allow other users to click a url and install the application. Using the project properties page I configured the relevant server details and successfully published the add-on on to the server.

But when I navigated to the specified install url I received 403 error This website requires you to login. After searching the web for a suitable answer I finally stumbled upon the answer on this web site:

In summary, don't forget to configure the .'vsto' MIME type with 'application/x-ms-vsto' on the virtual directory containing the add-in.

CodeKen - the replacement conference for StackOverflow DevDays

CodeKen London 2011 is a brand new developer conference delivering two days of hands-on coding oriented content over the 14 - 15th November in London. The event was organised in response to the cancellation of the Stackoverflow DevDays conferences and includes many of the original speakers like Jon Skeet, Robert Pickering and Richard Marr.

The talks cover a wide range of subjects including programming style, MongoDB, NodeJS, HTML5, REST services and more.

In addition to an eclectic mix of talks CodeKen 2011 is launching a developer side project competition. The goal is to encourage and publicise developers that are spending their spare time working on interesting projects. Five finalists will be given a free ticket to the conference and a chance to present their project at the event.
