CRM检索实体 - 错误：无法缩小“Microsoft.xrm.sdk.entity”类型的对象键入“crentities.list”

Question

我生成了如此：的CRM

CrmSvcUtil.exe /url:http://<servername>/<organizationname>/XRMServices/2011/Organization.svc
    /out:<outputfilename>.cs /username:<username> /password:<password> /domain:<domainname>
    /namespace:CRMEntities /serviceContextName:XrmServiceContext

.

对于 serviceContextName i set xrmserviceContext 。 我想使用下一个代码从CRM检索一些实体：

var context = new XrmServiceContext(myorgserv);
var marketingList = context.ListSet.Where(item => item.Id == new Guid("SOME GUID"));

.

，我收到错误：

Message "Unable to cast object of type 'Microsoft.Xrm.Sdk.Entity' to type 'CRMEntities.List'."

.

'添加到观看'后，我看到上下文中的每组实体都有相同的消息。 我错过了什么？

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();
