Differences Between Sandboxed and Farm Solutions

Farm Solutions

  • 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 to “farm solution,” the system’s IIS application pool recycles before SharePoint retracts or deploys the feature so as to release any files locked by the IIS worker process. Only the IIS application pool serving the SharePoint project’s site URL is recycled.

Sandboxed Solutions

  • 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.

Difference between claim based and classic authentication in sharepoint 2010

The following is an explanation of the 2 types of Authentication. This is well documented on the web!

Classic Mode: This is nothing but Windows Authentication. If any web application is created with Classic Mode Authentication then it cannot applicable to configure forms based authentication. That is basically it.

Claims Based: In SharePoint 2010 for a web application we can enable both windows AND forms authentication. In earlier implementation to do this, we have to create two web applications which has different zones and different authentication. But, with the new claims based authentication a single application can have the capability to configure both windows and forms under single URL. All this is possible because of the authentication framework is built on Microsoft Identify Foundation, and it uses “Geneva” framework to handle this authentication.

Convert from Classic Windows to Claims Based Authentication:  To configure a Windows Authentication application to use Forms Based Authentication then you can convert from Classic Mode to Claims Based. But, there is no UI exist for doing this conversion. The only way around is through PowerShell.

claimbasedauthentication

WARNING! This cannot be UNDONE!
At the PS Prompt Type the following commands and press enter after each one.

$app = get-spwebapplication “http://<your site’s URL>

$app.useclaimsauthentication = “True”

$app.Update()  Don’t forget the brackets!

IMPORTANT:  If an application is created using Claims Based Authentication and if you want to convert to Classic Mode then it is not possible either through the UI or through PowerShell.
