SharePoint 2013 – App Model 3 Tier Diagram

I needed a quick reference to introduce developers with the SharePoint 2013 App Model. 

For traditional ASP.Net and Dot Net coders there is a wide philosophy gap to cross when considering new applications written mostly in front-end JavaScript, HTML, and CSS.   Instead of coding “in” SharePoint (to augment the core product) we now code “next to” SharePoint (with additive REST/JSON endpoints).  

The stability which comes from this approach is significant.  We wan to run on-premise SharePoint similar to how Microsoft operates Office 365.   No more SharePoint customization lost during patching.   No more late night WSP and IISRESET outages.   Code can be modified more fluidly and IE breakpoints can even be set at a single user’s desktop when troubleshooting.   Exciting and powerful tools – which require a new way of thinking.

Please fee free to download the poster I made below.   Hope you find it helpful!

Merry Christmas – HTML5, JS, and CSS3

I wanted to thank all of you for reading my blog and wishing you a Happy Holiday season.   After passing exam 070-480 about HTML5, it seemed like a great time to practice new skills and draw a <CANVAS> based Christmas Tree here.   Enjoy!

Merry Christmas!

Say Happy Birthday with Code!

Most people just say “Happy Birthday” to each other over social networks like Facebook and Twitter with the same 14 predictable letters.   Why not say it with code?   If you’re a developer you already understand.  


   Before you ask … Yes, I really did write and run the QBasic 4.5 version in 16-bit mode running on Windows 7 x64.   Oh, and no it’s not my birthday.

With C# Console Application

With JavaScript

With Command Prompt

With QBasic 4.5  (oh yes I did!)



An Unhandled exception CryptographicException occurred in OWSTIMER.EXE

I recently saw this error while patching SharePoint with a Cumulative Update.   Most people will never see this.  However, you are not most people.  You run Visual Studio. 


Visual Studio is trying to help us out with an unhandled exception by asking about launching debug.  That’s all well and good but I didn’t write the code and have no plans to change it.

Best way to work with this is to disable the JIT (Just-In-time Debugger) by following a few simple Registry Key changes:
