What is the difference between sandboxed and farm solution in SharePoint 2010

Question

I am new to SharePoint 2010. What is the main difference between sandbox and farm solution. Can you give me 5 differences to remember. I googled, but there is lot of matter to understand. As a start up guy, i want to know the basic difference. Thanks for your help.

Answer 1

Farm Solution: Farm solutions, which are hosted in the IIS worker process (W3WP.exe), run code that can affect the whole farm. When you debug a SharePoint project whose Sandboxed Solution property is set.

Sandbox solution: Sandboxed solutions, which are hosted in the SharePoint user code solution worker process (SPUCWorkerProcess.exe), run code that can only affect the site collection of the solution. Because sandboxed solutions do not run in the IIS worker process, neither the IIS application pool nor the IIS server must restart. Visual Studio attaches the debugger to the SPUCWorkerProcess process that the SPUserCodeV4 service in SharePoint automatically triggers and controls. It is not necessary for the SPUCWorkerProcess process to recycle to load the latest version of the solution.

Answer 2

Farm Solutions:

• Farm solutions are hosted in the IIS worker process (W3WP.exe).
• If you run any code in farm solution the whole farm will got affected.
• If you deploy any feature or retract any feature the whole application pool got recycled.
• Since they are scoped as farm level, they have full trust access to all the resources.
• When the Sand boxed Solution property is set to False, selecting Build\Deploy will deploy the solution to the Farm Solution Gallery.

Sand boxed Solution:

• Sand boxed solutions are hosted in the SharePoint user code solution worker process (SPUCWorkerProcess.exe).

try to this link - The process runs under a CAS policy that restricts programmatic access to any resource outside the sandbox. - So it never restart the IIS application pool. - If you run any code it will affect only the site collection of the solution. - Helpful if you have shared hosting. - When the Sandboxed Solution property is set to True, selecting Build\Deploy Solution deploys the solution to the site collection Solution Gallery.

One major difference in the deployment is Farm solutions are installed and deployed. Sandboxed solutions are uploaded and activated.
