I generated entities from CRM like this:
CrmSvcUtil.exe /url:http://<servername>/<organizationname>/XRMServices/2011/Organization.svc
/out:<outputfilename>.cs /username:<username> /password:<password> /domain:<domainname>
/namespace:CRMEntities /serviceContextName:XrmServiceContext
For serviceContextName I set XrmServiceContext. I want to retrieve some entity from CRM using next code:
var context = new XrmServiceContext(myorgserv);
var marketingList = context.ListSet.Where(item => item.Id == new Guid("SOME GUID"));
And I'm getting error:
Message "Unable to cast object of type 'Microsoft.Xrm.Sdk.Entity' to type 'CRMEntities.List'."
After 'add to watch' I saw that every set of entities in context have the same message. What have I missed?
Problem solved. After initializing OrganizationServiceProxy, I have to call EnableProxyTypes method.
OrganizationServiceProxy orgserv;
ClientCredentials clientCreds = new ClientCredentials();
clientCreds.Windows.ClientCredential.UserName = username;
clientCreds.Windows.ClientCredential.Password = password;
clientCreds.Windows.ClientCredential.Domain = domain;
IServiceConfiguration<IOrganizationService> orgConfigInfo = ServiceConfigurationFactory.CreateConfiguration<IOrganizationService>(orgServiceUri);
orgserv = new OrganizationServiceProxy(orgConfigInfo, clientCreds);
orgserv.EnableProxyTypes();
Key thing is: orgserv.EnableProxyTypes();
