Early Binding
As you can see, so far the method to use and access the Organization service is a little difficult, and also you need to type the entities’ and attributes’ names, making the code hard to write. Fortunately this version of CRM 2011 has a new way to use the services by using early binding that provides IntelliSense support and better use of the code and .NET technologies such as the .NET Framework language-integrated query (LinQ). To use early binding, you will need to generate the entity classes by using the code generation tool called CrmSvcUtil.exe, which is a console application found in the sdk\bin folder of the CRM 2011 SDK.
An example of calling this tool is as follows:
CrmSvcUtil.exe /url:http://crm2011/Webfortis/XRMServices/2011/Organization.svc ...
