Introduction to Sandboxed Solutions

A new concept in SharePoint 2010 for rapid deployments of solutions.

A sandbox is a restricted execution environment that enables programs to access only certain resources, and that keeps problems that occur in the sandbox from affecting the rest of the server environment.

This is as simple as uploading a solution to solutions library. © 2011 www.salmanghani.co.uk. All rights

What can be achieved? Can access all classes under SPSite, SPWeb,

SPList and SPListItem Can create

web parts list definitions and list instances content types and fields modules workflows event receivers

Can read and write to the lists and libraries within same site collection

What is Good? Easy Deployment / Upgrade Activate / Deactivate Solutions No Server Reset Ideal for demonstration purpose on live

environments (Good for the business case) Good for developers Farm administrator can monitor and validate

solutions Easily convert to Farm solution Can be deployed by site collection

Limitations No code with elevate permissions Cannot use visual web parts No access to internet to make web service

calls No access to hard drive for read/write files Cannot access code that is not marked for

partially trusted callers No deployments to GAC

Development of Sandboxed

Support in Visual Studio

Develop IntelliSense Support No error messages if use wrong classes Instead run time exceptions

Deployment

Just upload to the solutions library (Solutions library per site collections)

Activate the solution Easy Upgrade Deactivate Remove

Debugging

Code runs under sandboxed worker process Debug against SPUCWorkerProcess.exe Debug rest of the page against w3wp.exe

Load Balancing for Sandboxed

Local load balancing The sandboxed solution runs on the same server that

received the request Remote load balancing  

The server that the sandboxed solution runs on is selected based on solution affinity, and the sandboxed solution is run on a server where it is already loaded and has already been run. This saves time in servicing the request for the solution.
