Q6: What is Shredded Storage?

Ans: With Shredded Storage feature enabled, every document and the Changes made to the document, is stored in SQL as multiple “Shredded BLOBS“.

Q30: Can you Create & Deploy Sandbox Solutions in SharePoint 2013?
Sandbox Solutions are depreciated in SharePoint 2013.You can still Create them and deploy them but they are not supported by Microsoft (not 100% sure about this though).

Q: Can we deploy Solutions Created in SharePoint 2010 in SharePoint 2013?
Yes. Most of the Solutions Should work fine but it is Recommended to Re-Create a Solution in Visual Studio 2012, Re-add all the features,Components and then deploy it to SharePoint 2013.

Q: Why Would you Recommend Re-Creating Solutions?

SharePoint 2013 provides Support for both 14 Hive and 15 Hive.Both the directories are Created by default.So if you deploy a SharePoint 2010 Solution that refers to say _layouts folder, the reference will be made to 14 Hive and not 15 Hive by default. To make the solution refer to 15 Hive’s _layouts folder you need to Re-Create the Solution in Visual Studio 2012 and fix the _layouts reference to add ’15’ into it.

14 Hive – _/layouts/custompage.aspx
15 Hive – _/layouts/15/custompage.aspx

Notice the reference of 15 in _layouts folder reference.

Q: How do you Force a Solution to be Deployed to 15 Hive and not 14 Hive?

If the solution was Created in Visual Studio 2010, you would add SharePointVersion=”15.0″ attribute in Solution’s manifest.xml file to force it to deploy in 15 Hive instead of 14 Hive.If the Solution however is Created in Visual Studio 2012, you don’t need to do anything, it gets deployed to 15 Hive by default.

Q: How do you Deploy Solution to 14 hive or 15 Hive without modifying Solution.

In SharePoint 2013 with the new “CompatabilityLevel” parameter of Install-SPSolution cmdlet you can now Deploy your wsp Solutions to 14 hive, 15 hive or both.

Q: Are there any Changes to Solutions deployed in \bin directory and GAC in SharePoint 2013?
You can no longer add partial trust Solution Packages to the \bin directory.Any files deployed to the \bin directory must be full trust. Any deployment scripts needs to be updated to make sure that they specify the correct trust level. After the release of .NET Framework 4.0, the GAC was split into two, one for each CLR.
c:\windows\assembly is the location for .NET versions 1.0 through 3.5 and c:\windows\\assembly is location for all the dlls for project Created in .NET Framework 4.0.
