Dynamics 365内部部署异常元数据包含无法解析的引用：

尝试从昨天开始调试我的控制台应用程序，但没有成功。我的剧本继续投掷：

元数据包含无法解析的引用：“https://xxxxxxx/XRMServices/2011/Organization.svc?wsdl&sdkversion=8.2”。

xxxxxxx是我的crm域名的占位符。

我使用Dynamics 365内部版本1612（8.2.0.749）（DB 8.2.0.749）。 Dynamics 365是IFD。

要创建控制台应用，我已经

1）使用最新动态365 Sdk版本8.2.1.1 Microsoft Dynamics 365 SDK

2）是的，也将此sdk安装到我的GAC中。然后重启我的服务器。

3）要检查我的组织服务端点是否正确，我还会在浏览器中粘贴我的OrganizationService端点地址https://xxxxxxx/XRMServices/2011/Organization.svc，并通过返回服务来工作。**

4）我使用Visual Studio 2013，.net framework 4.5.2

使用Dynamics 365在线试用版时，它的工作正常。

这是我的示例代码：

static void Main(string[] args)
        {

            IOrganizationService organizationservice;
            // Get the CRM connection string and connect to the CRM Organization

            ClientCredentials Credentials = new ClientCredentials();
            Credentials.UserName.UserName = "username";
            Credentials.UserName.Password = "password";

            Credentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;

            organizationservice = new OrganizationServiceProxy(
                new Uri("https://xxxxxxx/XRMServices/2011/Organization.svc"), null, Credentials, null);

        }

异常投掷： Exception throw:

当客户端计算机无法发送HTTP请求时，会发生此问题。客户端计算机无法发送HTTP请求，因为连接已关闭或不可用。今天我意识到我的数据库服务器使用TLS1.2而不是SSL作为连接到CRM App Server的协议，因此当通过console app建立从DB到CRM的连接时，我必须明确在ServicePointManager上设置TLS版本。只需在调用CRM组织服务之前随时运行此代码。

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

希望将来有人会受益。

当我将应用程序升级到CRM365时，我不得不改变连接的方式。这就是我正在使用的

string crmConnectionString = $@"Url=https://<domain>;
    AuthType=Office365;
    UserName=<username>;
    Password=" + <password>;
CrmServiceClient crmSvcClient = new CrmServiceClient(crmConnectionString);
OrganizationServiceProxy proxy = crmSvcClient.OrganizationServiceProxy;
proxy.EnableProxyTypes();
OrganizationServiceContext orgContext = new OrganizationServiceContext(proxy);

这不是一个前提，所以我不肯定它会起作用。但是连接字符串必须指定AuthType，并且您需要使用CrmServiceClient进行连接。

我们已将IServiceManagement用于crm版本2011及更高版本。下面显示了F＃中的一个示例 - 它几乎直接转换为C＃。

let authenticate uri username password domain =
  let m = ServiceConfigurationFactory.CreateManagement<IOrganizationService(uri)
  let cred = AuthenticationCredentials()
  cred.ClientCredentials.Windows.ClientCredential <- 
    new NetworkCredential(username, password, domain)
  let ac = m.Authenticate(cred)
  let proxy = new OrganizationServiceProxy(m, ac.ClientCredentials)
  proxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
  proxy
