Stefan joins me on CodeChat this time. He and his team have a Startup called BizLogr and have a well-established service - MileLogr - that helps business types track their expenses without a lot of work and hassle. Now they're working on a service that a lot of us are excited about.

It's called FreeBusy and it aggregates your various personal and business calendars and makes your net availability easily accessible to folks you collaborate with. So the "when are you free" dance just got a lot smoother!


SPECIAL NOTE: I'm going to be taking a long holiday break from CodeChat to spend time with family. My wife and I are expecting our second son really soon now. The CodeChat engine will fire back up on Monday, February 2. See you then.

    Since we recorded this show has adopted the new Office 365 API which supports OAuth. This means there's no need to share your password if you are on Office 365 like Jeremy is doing in the video (same for GMail, Google Apps, and Hotmail).

    In the process of doing so we created an OAuth provider for Azure AD (which is used implicitly by Office 365 tenants) that plugs into the OWIN auth middleware pipeline (which strangely enough isn't provided by Microsoft?!). It's open sourced at

    @LeonMeijer: Same here :( video goes black after min 18 which is unfortunate since the second half is about the API we're putting out.

    The video issue has been fixed! Although its cause will forever be a mystery. And just when it was getting suspenseful!

    @codefoster congratulations on the expansion of team Foster. I was behind on my codechat views so I can make up by watching the ones I had skipped or missed till you're back.
