The first step is to create a WCF REST service that will be used for downloading and uploading the file. I prefer to keep all my services in a separate WCF project. This project is then hosted in the IIS. Add a new Blank solution by the name of “FileHandling”. Add a new WCF Service Application and give it the name FileHandling.WCFHost. Right-click the FileHandling.WCFHost project in Visual Studio and go to the properties.

Under the Web tab click on “Use local IIS WebServer” and under the Project URL, write “and click on the button “Create Virtual Directory”. This will create a Virtual Directory for FileHandling.WCFHost in IIS. Go to IIS and check if the Virtual Directory is created. Ensure that the App Pool associated to the account is of.Net Framework 4.0. Also, the App Pool should be running under the identity of the user that has Read/write rights on any folder of the server.

WCF uses this identity for doing all its network operations. In this case I run the App Pool under my account, but it is not mandatory, you can choose a different account having permissions as well. Ensure that for the FileHandling.WCFHost, only Windows Authentication is enabled.With the preceding steps the IIS configuration is complete. Now it's time to add the service. Add a new WCFService in the FileHost.WCFHost project in VisualStudio and give it the name FileManagerService. In the IFileManagerService add the following methods. Please note that the Transfermode has been set to “Streamed”.

This will ensure that the file is streamed to the client. And also, notice that I have given maximum values to maxReceivedMessageSize, maxArrayLength, maxStringContentLength. This will ensure that large files can be transferred as well. Also note that for Security mode has been set to TransportCredentialsOnly and the ClientCredentialType has been set to Windows.

I am trying to build a WCF service that allows me to send large binary files from clients to the service.However I am only able to successfully transfer files up to 3-4MB. (I fail when I try to transfer 4.91MB and, off course, anything beyond)The Error I get if I try to send the 4.91MB file is:Exception Message: An error occurred while receiving the HTTP response to. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). Have you had a look at using Streaming Transfer?Windows Communication Foundation (WCF)can send messages using eitherbuffered or streamed transfers.

In thedefault buffered-transfer mode, amessage must be completely deliveredbefore a receiver can read it. Instreaming transfer mode, the receivercan begin to process the messagebefore it is completely delivered. Thestreaming mode is useful when theinformation that is passed is lengthyand can be processed serially.Streaming mode is also useful when themessage is too large to be entirelybuffered.
