Auto hosted app no longer supported in Office 365

Since early evening I was able to host my Light Switch apps in Office 365 SharePoint 2013 flavor.
But this morning I started to update the same and got this error message saying that "Auto hosted apps no longer supported in Office 365".

Earlier,I heard about lot of news and read articles that MS going to snap this feature in Office 365. But I though they could extend the auto-hosted preview for at least another couple of years (Still lot of developers need to understand the newly introduced App Models ) and time corporate strategically move from SharePoint 2010 to SharePoint 2013.

But I am not believed it in couple of month from Microsoft announcement (support ends for auto hosted app on Office 365).

Now its cent percent sure,your auto hosted app model no longer fit for Office 365.

Allow unsafe updates and Form digest

When you SharePoint application throws this error
Microsoft.SharePoint.SPException: The security validation for this page is invalid.

You need to ensure to use the "AllowUnsafeUpdates" property of SPWeb class has been set to true where ever you are trying to update the SharePoint items.
After you update revert back to true in your code.

Because SharePoint restricts the cross-site script injection when you are trying to update or change over the HTTP Requests.

FormDigest  is the counterpart to AllowUnsafeUpdates in Server object model in Client side object model.
All SharePoint Forms uses the "FormDigest" value by default.Just open any of the edit form in SharePoint in the browser and see the "View Source code" of the page.
You can see the "FormDigest" value.

SharePoint Exam 70-488 preparation

I am preparing the study notes for SharePoint 2013 Exam - 70-448 Developing SharePoint 2013 Core Solution.

Altogether there are seven topics to be covered in the exam. On my plan to create the study notes I successfully compiled the first topic "Plan and Design SharePoint Sites".

In this topic almost the same as SharePoint 2010.So if you have little bit development experience on creating the content types,columns,List Definition and basic site collection administrative tasks then the questions from this chapter is a simple.

I would encourage you not to rely on free dumps available on the net.Absolutely It will makes you fool and leading you to miserable SharePoint career.

So it always best to have real time experience with each of the above aspects. Even if you fail on exam, you aware of it how to implement and apply your knowledge to real time business requirement.

I wanted to share this document with everyone who wanted to take this exam.
