The underlying connection was closed: Unexpected error on a receipt

I have a web site that communicates with a WCF. This Wcf communicates with my "DAO" which is a Library class where I have the.edmx model for access to the bank. I referenced my DAO on WCF, and my WCF on my web site.

I am using Entity framework and webForms.

In Inner Exception is generating the following error.

The underlying connection was closed: Unexpected error on a receiving.

In my code generates the following error.

Error while receiving HTTP response to http://locahost:4614/Service.svc. This may be related to the fact that the service end point association does not use the HTTP protocol. It may also be related to the cancellation of a HTTP request context by the server (possibly due to shutdown of the service). See the server logs for more details

Can someone help me?

Add to your connectionString in the archive Web.config:

"MultipleActiveResultSets=true;"

Example:

"Data Source=.\SQLEXPRESS;Initial Catalog=MeuSistema;Integrated Security=True;MultipleActiveResultSets=true;"

  • @Marconi This "transform" we call "serialize". To answer your question I will need code examples. Can you please edit the question?

  • Camila, welcome to the OS-pt. Usually here on the site we add link with your content. Links themselves break and leave the content unusable. I recommend reading on tour to understand a little more about the operation of the site!

  • vlw Marconi and Everson, my inattention, I have already arranged the post change.
