Hi.
I've been using the CrmServiceClient with Tls12 in C# for a while now but last night it stopped working.
The LastCRMError is "Unable to Login to Dynamics CRM"
I haven't made any changes to this and testing the connection with XrmToolBox succeeds.
Any ideas
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
CrmServiceClient service = new CrmServiceClient(ConfigurationManager.ConnectionStrings["CRM"].ConnectionString);
Hi,
Try below code and you should be able to connect to CRM from console/c#
// e.g. yourorg.crm.dynamics.com
string url = "";
// e.g. you@yourorg.onmicrosoft.com
string userName = "";
// e.g. y0urp455w0rd
string password = "";
string conn = $@"Url = {url};AuthType = OAuth;UserName = {userName};Password = {password};
AppId = 51f81489-12ee-4a9e-aaae-a2591f45987d;
RedirectUri = app://58145B91-0C36-4500-8554-080854F2AC97;
LoginPrompt=Never;RequireNewInstance = True";
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
var svc = new CrmServiceClient(conn);
AppId and RedirectUri is provided by microsoft and it will work for all crm online instance.
Please mark my answer verified if i were helpful

public class DynamicsCeClientIdClient
{
public string TenantId = ""; // from your app registration overview "Directory (tenant) ID"
public string ClientId = ""; // from your app registration overview "Application (client) ID"
public string ClientSecret = ""; // secret generated in step 1
public string LoginUrl = "https://login.microsoftonline.com"; // aad login url
public string OrganizationName = ""; // check your dynamics login url, e.g. https://..dynamics.com
public string OrganizationRegion = "crm4"; // might be crm for north america, check your dynamics login url
public DynamicsCeClientIdClient(string organizationName, string clientId, string clientSecret, string tenantId, string region = "crm4")
{
TenantId = tenantId;
ClientId = clientId;
ClientSecret = clientSecret;
OrganizationName = organizationName;
OrganizationRegion = region;
}
private string GetServiceUrl()
{
return $"{GetResourceUrl()}/XRMServices/2011/Organization.svc/web";
}
private string GetResourceUrl()
{
return $"https://{OrganizationName}.api.{OrganizationRegion}.dynamics.com";
}
private string GetAuthorityUrl()
{
return $"{LoginUrl}/{TenantId}";
}
public async Task CreateClient(string sdkVersion = "9.1")
{
var context = new AuthenticationContext(GetAuthorityUrl(), false);
context.ExtendedLifeTimeEnabled = true;
var token = await context.AcquireTokenAsync(GetResourceUrl(), new ClientCredential(ClientId, ClientSecret));
return new OrganizationWebProxyClient(new Uri(GetServiceUrl()), true)
{
HeaderToken = token.AccessToken,
SdkClientVersion = "9.1"
};
}
public async Task CreateContext()
{
var client = await CreateClient();
return new OrganizationServiceContext(client);
}
public async Task TestApiCall()
{
var context = await CreateContext();
// send a test request to verify authentication is working
var response = (WhoAmIResponse)context.Execute(new WhoAmIRequest());
}
}
and this is how you create the client:
var organization = "myorg";
var clientId = "myclientid";
var clientSecret = "myclientsecret";
var tenantId = "mytenantid";
var region = "crm4";
var client = new DynamicsCeClientIdClient(organization, clientId, clientSecret, tenantId, region);
var c = client.CreateClient("9.1").Result;
