I try to not get into endorsing this thing or that on this blog, but there is something generating interest this week that I think is pretty cool, and it’s called the Hour of Code. The idea is to get students (or really anyone that wants to know more about programming IMO) to give it…

Debugging SharePoint Apps That Are Hosted In Windows Azure Web Sites
Today, I'm going to be the lazy human I'm so frequently accused of being by my somewhat faithful dog Shasta, and bring together two posts written by two other folks into one uber "ain't it cool how this all works together post" by me. Here are the two concepts we're combining today: Publishing a provider-hosted…
Tool to Get Token Signing Certificate Out of ACS
I continue to be regularly annoyed when I want to go snag the token signing certificate out ACS for use with federating to my various projects, like SharePoint sites.

Getting the Current User Identity in a Low Trust App in SharePoint 2013
Today's post comes primarily because it's a common question, but not because it's a particularly brilliant answer; maybe just a bit unexpected.

Creating a Yammer-Centric Security Setup for SharePoint 2013

If you are working with sensitive content then this is probably (but not absolutely) NOT the best solution for you. However, if you…
Another "Could not load file or assembly" Error Resolved

Another Tip if Visual Studio Times Out Trying to Deploy Your App in SharePoint 2013
I've had this happen to me, seemingly randomly, a number of times before. You open Visual Studio and create a new SharePoint App. You go through the wizard and then hit F5 to run, deploy and debug your app. Something happens along the way though…you watch the output window and it just keeps counting time…

How To Control App Token Lifetimes in SharePoint 2013
Today's post is the first selection from the little twitter contest I announced on the Share-n-Dipity blog a few days ago: http://blogs.technet.com/b/speschka/archive/2013/09/04/use-social-tools-to-tell-me-what-you-want-to-see-here-next.aspx. Shariq wanted to know more about the lifetime for high trust app tokens, as he tweeted here: @speschka – I would be keen to understand more around caching tokens in High Trust Apps….
Security in SharePoint Apps – Part 8
PREVIOUS: Security in SharePoint Apps – Part 7 For this, the very last in the series, I just wanted to briefly talk at a high level about the process you should be doing when developing an App for a SharePoint site that uses SAML (or FBA for that matter). I’ve already written a detailed post…
