I need to understand how I get the HttpResponseMessageProperty from an async web service request.
I'm attempting to migrate a C# Console App into an Azure Function App and the only methods now available in the connected service are async.
The error I'm getting is:
System.Private.ServiceModel: This OperationContextScope is being disposed out of order.
From what I've read, the error is likely to be a result of the OperationContextScope running on a different thread and OperatonContextScope is thread specific.
There is advice on the MS docs site which states:
If you need to call "await" for an async call, use it outside of the OperationContextScope block.
Not sure how I achieve this though, hence my question here.
Here's my code:
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport)
{
AllowCookies = true,
SendTimeout = new TimeSpan(0, httpTimeout, 0),
ReceiveTimeout = new TimeSpan(0, httpTimeout, 0),
MaxBufferSize = int.MaxValue,
MaxReceivedMessageSize = int.MaxValue
};
/* set the https endpoint and create the service client object */
EndpointAddress serviceEndpoint = new EndpointAddress(serviceBaseUrl + serviceName);
AuthenticationServicePortTypeClient service = new AuthenticationServicePortTypeClient(binding, serviceEndpoint);
/* set the request attributes and login */
Login loginRequest = new Login()
{
UserName = authUser,
Password = authPass,
DatabaseInstanceId = databaseInstance,
DatabaseInstanceIdSpecified = true
};
using (new OperationContextScope(service.InnerChannel))
{
LoginResponse1 loginResponse = await service.LoginAsync(loginRequest);
if (loginResponse.LoginResponse.Return)
{
HttpResponseMessageProperty response = (HttpResponseMessageProperty)OperationContext.Current.IncomingMessageProperties[HttpResponseMessageProperty.Name];
sessionCookie = response.Headers["Set-Cookie"];
}
}
The exception is throw on the HttpResponseMessageProperty line.
I just need to be able to obtain the cookie from the header.
Any help would be extremely appreciated.
