OrganizationServiceProxy vs CrmServiceClient ?

(0) ShareShare
ReportReport
Posted on by Genato 56

Hello,

can anyone explain what is the difference between this two "services" when opening connection to CRM from web application?

Why should i use one over other one?

And this thing is confusing, why do you create an instance of CrmServiceClient with OrganizationServiceProxy ?

CrmServiceClient(OrganizationServiceProxy);

or even better after you create an instance of CrmServiceClient, why do you cast it to IOrganizationService 

 

CrmServiceClient conn = new Xrm.Tooling.Connector.CrmServiceClient(connectionString);
private IOrganizationService _orgService;
_orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

Thank you :)

    you can just use CrmServiceClient and you don't need to cast to IOrganizationService

    CrmServiceClient service = new Xrm.Tooling.Connector.CrmServiceClient(connectionString);

    and after use service with the same methods as IOrganizationService, so you can do service.Create, service.Update, service.RetrieveMultiple

    Hi Guido

    I've tried this but I'm seeing a error. Any advise please?

    Dim service As CrmServiceClient = New CrmServiceClient(ConfigurationManager.ConnectionStrings("CRM").ConnectionString)


    Error at create method;

    Object reference not set to an instance of an object.

    Very late response but I think its good to put something here rather than leave an open question.
    In this case, put ConfigurationManager.ConnectionStrings("CRM").ConnectionString in to a variable then check it has a value.

    This is just a logical error and not related to CRM. 
    Chances are that CRM section wasn't found in the config so you passed a null to the next level.
