Connection to Dynamics 365 in C# RRS feed

  • Question

  • Hi,

    I am using C# to connect to Dynamics 365. I used the same code and it works for one instance and not for another one. I get the following error : "ID3007: The element 'pp' with namespace '' is unrecognized."

    The code is the following

    namespace ConnectToCRM {
    	class Program {
    		static void Main(string[] args) {
    					IOrganizationService organizationService = null;
    					ClientCredentials clientCredentials = new ClientCredentials();
    					clientCredentials.UserName.UserName = "";
    					clientCredentials.UserName.Password ="MyPass";
    					// For Dynamics 365 Customer Engagement V9.X, set Security Protocol as TLS12
    					ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
    					// Get the URL from CRM, Navigate to Settings -> Customizations -> Developer Resources
    					// Copy and Paste Organization Service Endpoint Address URL 
    					organizationService = (IOrganizationService)new OrganizationServiceProxy(new Uri(""),
    					null, clientCredentials, null);
    					if (organizationService != null)
    						Guid userid = ((WhoAmIResponse)organizationService.Execute(new WhoAmIRequest())).UserId;
    						if (userid != Guid.Empty)
    							Console.WriteLine("DOTNET 2015 : Connection Established Successfully...");
    					Console.WriteLine("DOTNET 2015 : Failed to Established Connection!!!");
    				catch (Exception ex)
    				Console.WriteLine("DOTNET 2015 : Exception caught - " + ex.Message);

    I have the "Microsoft.CrmSdk.CoreAssemblies" package installed V and targeting the .NET Framework 4.7.2.

    the first instance in CRM that works fine with my code is a free trial with Server version: 9.1.0000.6227

    the second instance that is giving me the error is another free trial with Server version: 9.1.0000.6421
