ECMA SCRIPT SHAREPOINT 2010

SharePoint provides two sets of JavaScript file: minified and unminified/debug version.
For example sp.js file is minified and sp.debug is minified and debug version. The default master page in SharePoint has a scriptmanager in the page and whose ScriptMode is set to auto, as a result the minified version of js file loaded.
If you want to use debug version you can add the <deployment retail="false" /> in the <system.web> section of the web.config. In the production you need to remove this entry to make sure minified version is used.

Managed Client
DLL's needed : Microsoft.SharePoint.Client.dll, Microsoft.SharePoint.Client.Runtime.dll. Find these files in the 14/ISAPI folder. Usually, the location would be at "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI".

Silverlight
Microsoft.SharePoint.Client.Silverlight.dll and Microsoft.SharePoint.Client.Silverlight.Runtime.dll. They find at "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\ClientBin".

ECMAScript
SP.js file - The file fund at "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS".
