Using WSDL Proxies with CRM Online. It's different outside of North America

I've been spending more time than I'd like using WSDL Proxies with CRM Online (i.e. when I can't use the .Net 4.0 OrganizationServiceProxy class). I'll write up some more about this soon, but this is a quick post about a specific issue with connecting to CRM Online for an organisation in EMEA, rather than North America, which I've not found documented anywhere.

I was basing my code on the wsdlbasedproxies example in the CRM 2011 SDK. Once you find it, this code is reasonably well documented.

However, when testing it, I could connect to the IDiscoveryService without problems, but continually got the error 'An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail' when connecting to the IOrganizationService.

Ultimately the issue was with the AppliesTo constant. The setup.txt instructions tell you to set this based on data in the element from the Discovery.svc wsdl. This gave me "urn:crmemea:dynamics.com" when connecting to an Online organisation in EMEA, which worked for the IDiscoveryService, but not IOrganizationService.

** Update 2012-07-11. IOrganizationService now also uses urn:crmemea:dynamics.com **

So, this needed a few minor code changes to the code in Online\program.cs, as you need different tokens for each service. For EMEA, I used the following:

private const string AppliesToDiscovery = "urn:crmemea:dynamics.com";
private const string AppliesTo = "urn:crmemea:dynamics.com";

static void Main(string[] args)
//Authenticate the user
SecurityToken tokenDiscovery = Authenticate(UserName, UserPassword, AppliesToDiscovery, Policy, IssuerUri);
SecurityToken token = Authenticate(UserName, UserPassword, AppliesTo, Policy, IssuerUri);
//Execute the sample
string serviceUrl = DiscoverOrganizationUrl(tokenDiscovery, OrganizationUniqueName, DiscoveryServiceUrl);
ExecuteWhoAmI(token, serviceUrl);

Update July 2012: AppliesTo for EMEA should now be urn:crmemea.dynamics.com. See http://mscrmuk.blogspot.co.uk/2012/07/using-wsdl-proxies-with-crmonline.html
