ClientContext and sharepoint

Question

If this is for Client so the Client does not need to have SharePoint installed on its computer to get it work? am I right?

I need some information to understand it, the code executed on client side so why he needs to have Sharepoint?

Answer 1

Client Object Model in SharePoint has basically 3 applications, nore requiring SP installed, but for which one you need certain libraries available during development: 1. ECMA Client OM - to be used by Javascript - no SharePoint whatsoever but you need the libraries (SP.js, etc.) 2. Managed - For use from Windows Forms, Console Applications, etc. - in this one you need the Managed SharePoint assemblies 3. Silverlight Client OM - Same as #2 but you need to also link to some Microsoft.SharePoint.Client.Silverlight and Microsoft.SharePoint.Client.Silverlight.Runtime

When using the Silverlight Client Object Model you have two way of getting a valid ClientContext.

Either you specify the url of the SharePoint site to work with in the constructor to a ClientContext like this:

ClientContext clientContext = new ClientContext("http://sharepoint");

Or the <object> tag used to load your SilverLight application should contain a <param> tag with name "initParams" and a value MS.SP.url = url. So you could use something like:

<param name="initParams" value="MS.SP.url=<%= Microsoft.SharePoint.Utilities.SPHttpUtility.HtmlEncode(Microsoft.SharePoint.SPContext.Current.Web.Url) %>" />

to specify it. The OOTB Silverlight web part does this. Then you can use ClientContext.Current.
