Hello,

I am creating a an Azure API that connects to the CDS Web API and I am trying to use the class CDSWebApiService mentioned in the samples below:

https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/webapi/samples/cdswebapiservice

I have rebuilt all code in my API Project but the case that when i use the post to create a contact based on the sample , although the contact is physically created but there is no response getting back

 string connectionString = ConfigurationManager.ConnectionStrings["Connect"].ConnectionString;
 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;

 ServiceConfig config = new ServiceConfig(connectionString);
 using (CDSWebApiService svc = new CDSWebApiService(config))
 {
 // Console.WriteLine("--Starting Basic Operations--");

 
 ////Create a contact
 var contact1 = new JObject
 {
 { "firstname", "Rafel" },
 { "lastname", "Shillo" }
 };
 Uri contact1Uri = svc.PostCreate("contacts", contact1);
 return contact1Uri.AbsolutePath;
 }

Any Help will be appreciated !

I suspect there may be an issue with the async implementation that you are using - can you try and implement the call using the PostCreateAsync method?

@ScottDurow
I tried to use PostCreateAsync but it returned an Exception Task was cancelled.

This is how i call it from my API , it just never returns the URI
public string Post([FromBody]string value) { string connectionString = ConfigurationManager.ConnectionStrings["Connect"].ConnectionString; ServiceConfig config = new ServiceConfig(connectionString); using (CDSWebApiService svc = new CDSWebApiService(config)) { // Console.WriteLine("--Starting Basic Operations--"); ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11; //Create a contact var contact1 = new JObject { { "firstname", "Mira" }, { "lastname", "WEB API" } }; return svc.PostCreate("contacts", contact1).ToString(); } }
