The SharePoint Client Object Model – CSOM has had a number of upgrading, compared to the previous version. Currently, the Client.svc, which was hidden at all times, is accessible by developers for being able to make REST appeals in order to be able to POST and Get requests.
The Client.svc executes the main features of oData stipulations.
SharePoint Client Object Model – Best Practices
• Applying Methods/Properties in the same query that restore client objects in a different method call.
A client object is different from a value object and it can be applied in a different method call, but within a similar query. The value object, in a .NET remoting, is a structure or value that is assembled by the value, whereas the client object is assembled by reference. For instance, UrlFieldValue is a value object, and ListItem is an example of a client value.
The subsequent server object in a client library has the {ClientCallable(valueObject=true)} ascribe. The values represented might not have methods, but have only properties. Ints and strings, some primal types, are regarded as value objects. Each value will be assembled between the server and the client, and the standard value of a ValueObject is always False. The client object is a complement of a value object. Suppose the matching server object the attribute, ClientCAllable(ValueObject = False), then that implies that the object will be a client object.
Call ClientContext.Execute Query prior to Accessing any value attribute
The Sharepoint Client Object Model compels that you apply a programming that almost resemble an SQL. For that, you will be required to specify what you need and perform the query, prior to accessing any data. If you attempt to display a title for your SharePoint site, without following the right procedure, an exception will be executed. For you to successfully create the title, you will need to:
• Create either a stored procedure or a makeshift SQL query.
• Perform an SQL query
• And Read the results from an SQL.
In the CSOM, you will be building a query, once you call a method. The queries build up, but they will not be set to the server, awaiting you to make an ExecuteQuery call. Other than that, you will be required to include a using attribute for the System.Linq. You will also add a pseudonym to the using attribute for the MSC – Microsoft SharePoint Client name in order to refer to the classes explicitly.
Apply Condition Scope to Test Preconditions, Prior to Loading Data
You will be required to place a provisional scope by applying a Conditional Scope Object, in order to execute the code conditionally. For instance, you will be required to recover the list property when the list has a value. In addition, you will be required to include attributes for the System.Linq and System.Collection.Generic. You should also include a pseudonym to the using attribute for the Microsoft.SharePoint.Client name filed, in order to refer the classes decidedly.
These are some of the best practices of SharePoint Client Object Model that will help you achieve a successful and functional SharePoint site.
