I've got the following code to connect to Dynamics 365 Online organization. It throws a null reference exception on orgService.Execute(new WhoAmIRequest()); and error log is below the code. I've tried this on two machines with different console apps. I've tried both the 8.2 and 8.0 SDK DLLs. If I rewrite this using CrmConnection with the 7.x SDK DLLs everything works fine. I can browse to the organization using the same credentials (cut & pasted to be sure there is not a typo.)
The connection string format is taken from the example at https://msdn.microsoft.com/en-us/library/mt608573.aspx:
Named account using Office 365
<add name="MyCRMServer"
-connectionString="AuthType=Office365;Username=jsmith#contoso.onmicrosoft.com;
Password=passcode;Url=https://contoso.crm.dynamics.com"/>
The basic code.
var connectionString = #"Url=https://ORGNAME.crm.dynamics.com; Username=username#ORGNAME.onmicrosoft.com; Password=43JF##$j##Ha; Authype=Office365;";
var client = new CrmServiceClient(connectionString);
var orgService = (IOrganizationService)client.OrganizationWebProxyClient ?? client.OrganizationServiceProxy;
orgService.Execute(new WhoAmIRequest());

As per latest Microsoft recommendation we are not supposed to use “AuthType=Office365”.
https://learn.microsoft.com/en-us/powerapps/developer/common-data-service/authenticate-office365-deprecation
We can use Application Account (Client ID & Secret Key) to generate Token & access Dynamics CRM Organization Service. But if you want to use User ID & PWD then Use (AuthType = OAuth)
Sample Code :
string connectionString = "AuthType = OAuth; Url = 'https://*****.crm.dynamics.com'; Username = '*******'; Password = '*******'; AppId = 51f81489-12ee-4a9e-aaae-a2591f45987d; RedirectUri = app://58145B91-0C36-4500-8554-080854F2AC97;LoginPrompt=Never";
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
CrmServiceClient crmServiceClient = new CrmServiceClient(connectionString);
WhoAmIResponse whoAmIResponse = crmServiceClient.Execute(new WhoAmIRequest()) as WhoAmIResponse;
Note : While trying to use this from Azure Function I got below errors :
ERROR REQUESTING Token FROM THE Authentication contextNeed a non-empty authority
One or more errors occurred. => An error occurred while sending the request. => The underlying connection was closed: An unexpected error occurred on a send. => Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. => An existing connection was forcibly closed by the remote hostERROR REQUESTING Token FROM THE Authentication context
CurrentAccessToken = 'crmServiceClient.CurrentAccessToken' threw an exception of type 'System.NullReferenceException'
Easily you can resolve these using just one additional line : ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Pls let me know if you are facing any other issues.

Have you tried passing the parameters directly to the CrmServiceClient instead of the connection string?
I can connect successfully to Dynamics365 by using this following method
public CrmServiceClient(string crmUserId, SecureString crmPassword, string crmRegion, string orgName, bool useUniqueInstance = false, bool useSsl = false, OrganizationDetail orgDetail = null, bool isOffice365 = false);
And here's how I applied
var pwd = ConvertToSecureString("userpassword");
CrmServiceClient client = new CrmServiceClient("user#mail.com", pwd, "NorthAmerica", "orgname", isOffice365: true);
And here's the method to convert the password to secure string
private System.Security.SecureString ConvertToSecureString(string password)
{
if (password == null)
throw new ArgumentNullException("missing pwd");
var securePassword = new System.Security.SecureString();
foreach (char c in password)
securePassword.AppendChar(c);
securePassword.MakeReadOnly();
return securePassword;
}
I was getting error
Unable to login to Dynamics CRM, Error was :
Data[0] = "The provided uri did not return any Service Endpoints!
I received this error when attempting to connect to Dynamics using a connection string with AuthType=ClientSecret. Previously I was connecting successfully using username and password with a connection string of the form
"Url={dynamicsConnectionString};Username={username};Password={password};AuthType=Office365;"
The connection string was changed to have the form
"AuthType=ClientSecret;RequireNewInstance=false;Url={CrmDynamicsPrivatePrimaryConnection};ClientId={CrmDynamicsPrivateClientId};ClientSecret={CrmDynamicsPrivateClientSecret};LoginPrompt=Never;"
The error occurred because I was using an outdated version of Microsoft.CrmSdk.XrmTooling.CoreAssembly. I was using version 9.0.2.27, and according to a web report, version 9.1.0.13 is needed for connecting with ClientSecret. I updated to version 9.1.0.68 using NuGet, and the Dynamics connection worked.
I was struggling on fixing this issue because everything I did except installing higher version (On MS docs also They didn't mentioned this) of Microsoft.CrmSdk.XrmTooling.CoreAssembly since lower version of this dll doesn't support ClientSecret authentiation.

I have some integration code that intends to use the Organization Service via the CRM SDK.
On one environment, creating an IServiceManagement<IOrganizationService>:
IServiceManagement<IOrganizationService> orgServiceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(new Uri("dynamics uri")));
and then authenticating with service account credentials:
AuthenticationCredentials authCredentials = new AuthenticationCredentials();
authCredentials.ClientCredentials.UserName.UserName = _config.GetValue<string>("Dynamics:Username");
authCredentials.ClientCredentials.UserName.Password = _config.GetValue<string>("Dynamics:Password");
AuthenticationCredentials tokenCredentials = orgServiceManagement.Authenticate(authCredentials);
works fine.
On another Dynamics environment, the call to GetServiceManagement fails with the following error message:
System.InvalidOperationException

POSTing to this URL in PostMan yields the HTML for a browser login page, which explains the failure; this isn't what the ServiceConfigurationFactory expects. The scenario is not user-interactive, so this would never make sense, there is no browser and no user able to interact with it.
What do I have to change in Dynamics CRM Online to stop it doing this, and make it just work normally?
Do you instantiate your OrganizationServiceProxy depending on the AuthenticationProviderType right after the lines of code you have posted? Like this
var orgServiceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(new Uri(ConfigurationManager.AppSettings["CrmUrlService"]));
var authCredentials = new AuthenticationCredentials();
authCredentials.ClientCredentials.UserName.UserName = ConfigurationManager.AppSettings["CrmUserName"];
authCredentials.ClientCredentials.UserName.Password = ConfigurationManager.AppSettings["CrmPassword"];
var tokenCredentials = orgServiceManagement.Authenticate(authCredentials);
IOrganizationService _service;
switch (orgServiceManagement.AuthenticationType)
{
case AuthenticationProviderType.ActiveDirectory:
_service = new OrganizationServiceProxy(orgServiceManagement, tokenCredentials.ClientCredentials);
break;
default:
_service = new OrganizationServiceProxy(orgServiceManagement, tokenCredentials.SecurityTokenResponse);
break;
}
Even if this solves your problem, I recommend that you use CrmServiceClient instead. This class can be found in Microsoft.Xrm.Tooling.Connector dll. It is the go to authentication class when building Windows client applications that connect to Microsoft Dynamics 365. More information on this can be found here
Here is an example on how to initialize CrmServiceClient when connecting to Dynamics 365 online using Office 365:
var myConnectionString = "Url=https://[YourOrganization].crm4.dynamics.com;Username=[YourUser];Password=[YourPassword];AuthType=Office365;";
var crmClient = new CrmServiceClient(myConnectionString);
//Do your stuff
var response = crmClient.Execute(new WhoAmIRequest());
If you need other authentication methods in Dynamics Online check how to build your connection string here.
For on-premises check how to build your connection string here.
am trying to create a console application that connects to CRM 2016 (On Prem) using the 2016 SDK.
The below code fails. The conn.LastCrmError has the following details and the orgService is null.
Unable to Login to Dynamics CRMOrganizationWebProxyClient is null OrganizationServiceProxy is null OrganizationWebProxyClient is null OrganizationServiceProxy is null.
var connectionString = #"Url=http://xxxx/xxxx/; Username=xxxx; Password=xxxx;";
CrmServiceClient conn = new CrmServiceClient(connectionString);
IOrganizationService orgService = conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
The connection works when running old code, below, using the 2015 SDK
var connectionString = #"Url=http://wxxxxx/xxxx/; Username=xxxxx; Password=xxxxx;";
IOrganizationService orgService2 = new OrganizationService(CrmConnection.Parse(connectionString));
var results = orgService2.Execute(new WhoAmIRequest());
Any suggestions on how to resolve this?

This exception in most cases is thrown when you can't connect to CRM instance. Are you sure your connection string is ok? Here are connections strings described. Maybe lack of 'domain' attribute is the problem?

MS support resolution, by add this line in the code before you connect to CRM.
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;
//need to add ref. System.Net dll
or
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
You are missing the AuthType in the connection string:
AuthType=AD;
I am getting frustrated with this error.
I am using the .NET Client library to connect and to post products to google shopping.
I keep getting this error (I have replaced the correct Id with x's):
The remote server returned an error: (400) Bad Request.
[GDataRequestException: Execution of request failed: https://content.googleapis.com/content/v1/xxxxxx/items/products/schema]
Google.GData.Client.GDataRequest.Execute() +159
In my code I am doing it like this after successfull authentication:
string serviceName = "structuredcontent";
string userAgent = "content-api-example";
GOAuth2RequestFactory requestFactory = new GOAuth2RequestFactory(serviceName, userAgent, _parameters);
_service = new ContentForShoppingService(userAgent, accountId);
_service.RequestFactory = requestFactory;
ProductEntry productEntry = _service.Insert(entry);
Can anyone see what is wrong?
I am trying to customize some lists for SharePoint Online and since I am new to the subject I do not know how to connect to the service.
When I use NAPA and from the cloud use the option "Edit in Visual Studio", I am prompted for credentials automatically when the project opens.
However, when I start from bottom-up, i.e. open a new project in Visual Studio, add all necessary dlls, this part of code throws an error (it is an authentication issue):
ClientContext context = new ClientContext("https://MYURL.sharepoint.com/n/");
context.ExecuteQuery();
I am using Microsoft.SharePoint.Client;
The error message:
An unhandled exception of type 'System.Net.WebException' occurred in Microsoft.SharePoint.Client.dll
Additional information: The remote server returned an error: (403) Forbidden.
I think I am missing part of the code which is responsible for authentication and which in case of NAPA app is hard-coded.
How can I authenticate to SharePoint Online? (it is enough if my code runs just once, it's not an app, I don't want to package it and publish)
I am guessing it has something to do with http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.sharepoint.remote.authentication.aspx, but that's as far as I got.
How to authenticate against SharePoint Online using the managed CSOM
The CSOM for SharePoint 2013 introduces the SharePointOnlineCredentials class that allows to perform an active authentication to SharePoint Online.
Example
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter the URL of the SharePoint Online site:");
string webUrl = Console.ReadLine();
Console.WriteLine("Enter your user name (format: username#tenant.onmicrosoft.com)");
string userName = Console.ReadLine();
Console.WriteLine("Enter your password.");
SecureString password = GetPasswordFromConsoleInput();
using (var context = new ClientContext(webUrl))
{
context.Credentials = new SharePointOnlineCredentials(userName,password);
context.Load(context.Web, w => w.Title);
context.ExecuteQuery();
Console.WriteLine("Your site title is: " + context.Web.Title);
}
}
private static SecureString GetPasswordFromConsoleInput()
{
ConsoleKeyInfo info;
//Get the user's password as a SecureString
SecureString securePassword = new SecureString();
do
{
info = Console.ReadKey(true);
if (info.Key != ConsoleKey.Enter)
{
securePassword.AppendChar(info.KeyChar);
}
}
while (info.Key != ConsoleKey.Enter);
return securePassword;
}
}
I am using
I am logged into a remote server for accessing Visual studio as well as MS CRM. I have taken sample code from SDK and trying to run the code:
CrmAuthenticationToken token = new CrmAuthenticationToken();
token.AuthenticationType = 0;
token.OrganizationName = "AdventureWorksCycle";
CrmService service = new CrmService();
service.Url= "http://10.16.16.205:5555/mscrmservices/2007/crmservice.asmx";
service.CrmAuthenticationTokenValue = token;
service.Credentials = new System.Net.NetworkCredential"username", "password", "domain");
// Create the account object.
account account = new account();
// Set the properties of the account object.
account.name = "Fourth Coffee123";
account.address1_line1 = "29 Market St.";
account.address1_city = "Sam";
account.address1_stateorprovince = "MT1";
account.address1_postalcode = "9999";
account.donotbulkemail = new CrmBoolean();
account.donotbulkemail.Value = true;
// Create the target object for the request.
TargetCreateAccount target = new TargetCreateAccount();
// Set the properties of the target object.
target.Account = account;
// Create the request object.
CreateRequest create = new CreateRequest();
// Set the properties of the request object.
create.Target = target;
// Execute the request.
CreateResponse created = (CreateResponse)service.Execute(create);
I am using Crm Web Service for this, but Its throwing exception:

One thing you are missing is a real username and password. I am assuming that you have omitted this for the purposes of this question.
Have you checked the security role on the user that you are using for the web service call? Add this user to the System Administrator role if you haven't already.
With CRM often times, this error has nothing to do with security but something else altogether.
First turn on CRM tracing and look there. This will give you more error detail. Here's how:
http://support.microsoft.com/kb/907490
Also you can try to use my exception formatter to get more detail on the error. This is an extension class that will allow you to format the exception and print it to stdout or to the http response. Find it here:
http://paste.ly/5Y66
Use it this way:
try {
// do all your stuff
} catch (Exception ex) {
ex.Print();
}
Notice that in the formatted exception output, you can see the "Details" property deserialized such that you can see the text version. This is where CRM hides the real exception most of the time.
