Hi Iswaraya,
can you add TLS1.2 code before calling CrmServiceClient. I have highlighted the changed section
All responses (
Answers (
public class CRMService
{
public IOrganizationService _orgService;
public IOrganizationService CreateConnection(string un,string pw)
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
var conn = new CrmServiceClient(GetConnectionString(un, pw));
_orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
if (_orgService == null)
{
return null;
}
return _orgService;
}
private string GetConnectionString(string username, string password)
{
try
{
var connectionString = default(string);
string strOrgUrl = ConfigurationManager.AppSettings["OrganizationUri"].ToString();
try
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
connectionString = "RequireNewInstance=True; Url=" + strOrgUrl + "; Username=" + username + "; Password=" + password + "; AuthType=Office365;";
}
catch (Exception ex)
{
throw;
}
return connectionString;
}
finally
{
}
}
}
Thanks

Hi,
This is my code , i already used this SecurityProtocol but error remain same
public class CRMService
{
public IOrganizationService _orgService;
public IOrganizationService CreateConnection(string un,string pw)
{
var conn = new CrmServiceClient(GetConnectionString(un, pw));
_orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
if (_orgService == null)
{
return null;
}
return _orgService;
}
private string GetConnectionString(string username, string password)
{
try
{
var connectionString = default(string);
string strOrgUrl = ConfigurationManager.AppSettings["OrganizationUri"].ToString();
try
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
connectionString = "RequireNewInstance=True; Url=" + strOrgUrl + "; Username=" + username + "; Password=" + password + "; AuthType=Office365;";
}
catch (Exception ex)
{
throw;
}
return connectionString;
}
finally
{
}
}
}
Hi,
It generally happens when you are using tooling connector for connection to Dynamics 365 Online.
In order to resolve the issue you have to specify the security protocol before you make calls to your Microsoft.Xrm.Tooling assembly.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
The connection to Dynamics 365 will not be available unless TLS12 is being used as Security Protocol.connection.
Hope it helps.
BR,
Judy

Appreciate to Mark as Answer if it is useful.
Hi Iswarya,
This might be TLS1.2 issue. Please add following highlighted code before calling IOrganizationService.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; CrmServiceClient crmSvc = new CrmServiceClient(ConfigurationManager.ConnectionStrings["online"].ConnectionString); IOrganizationService _orgService = crmSvc.OrganizationWebProxyClient != null ? crmSvc.OrganizationWebProxyClient : (IOrganizationService)crmSvc.OrganizationServiceProxy;
<connectionStrings>
<add name="Online" connectionString="; Username=; Password=; authtype=Office365" />
</connectionStrings>
Thanks

Maybe this, then.. the TLS 1.2 requirement is relatively new, I believe.. But your Dynamics instance may have been updated recently so it may be enforced now:

Hi,
did you try the latest nuget package for Microsoft.CrmSdk.XrmTooling.CoreAssembly ?
It was released 12 days ago, though, not yesterday.. so not sure if that's the problem.. But, if your code stopped working suddenly, that's the first thing I would try:
