CrmService proxy for plug-ins that execute in the child pipeline.

We always come across creating a CrmService Proxy for plug-ins that execute in the child pipeline. In a Child pipeline, you must instantiate the CrmService or MetadataService manually. We just need to check the InvocationSource Property (Child = 1, Parent = 0) of the IPluginExecutionContext. Pass the InvocationSource Property value to the below method.

Below is very simple code which creates a proxy.

public class CRM4_ServiceProx
{


/// The execution context that was passed to the plug-in's Execute method.
/// Set to True to use impersonation.
/// A CrmServce instance.
        private CrmService CreateCrmService(IPluginExecutionContext context, Boolean flag)
        {
            CrmAuthenticationToken authToken = new CrmAuthenticationToken();
            authToken.AuthenticationType = 0;
            authToken.OrganizationName = context.OrganizationName;

            // Include support for impersonation.
            if (flag)
            authToken.CallerId = context.UserId;
            else
            authToken.CallerId = context.InitiatingUserId;

            CrmService service = new CrmService();
            service.CrmAuthenticationTokenValue = authToken;
            service.UseDefaultCredentials = true;

            // Include support for infinite loop detection.
            CorrelationToken corToken = new CorrelationToken();
            corToken.CorrelationId = context.CorrelationId;
            corToken.CorrelationUpdatedTime = context.CorrelationUpdatedTime;
            corToken.Depth = context.Depth;
	    //Get the server name form registry
            RegistryKey regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\MSCRM");

            service.Url = String.Concat(regkey.GetValue("ServerUrl").ToString(), "/2007/crmservice.asmx");
            service.CorrelationTokenValue = corToken;

            return service;
        }
    
}
