How is WCF used to transfer large data?
While the former is used to enforce security at the transport level, the latter is used to encrypt the message that is passed between the WCF server and the client. Therefore, sharding is an ideal solution for transferring large amounts of data over the wire using WCF in high data traffic scenarios. You can learn more about this in this MSDN article.

How to send a 75MB file using WCF?
This article tries to solve this problem using WCF and TCP and streaming, in this article we will build the client and server at the end, we will be able to send a 75 MB file in less than 12 seconds. The receiver will provide the sender with a simple method called (Put) this method will take a FileTransferRequest object, as you can see in the code:
How to transfer a file using WCF-codeproject?
The (Put) method will take a FileTransferRequest object and call the SaveFileStream method, which will speak the file content as a byte and convert it to stream, then save it to the given folder path, this is what the FileTransferRequest looks like:
What size message can I send in WCF?
The default message size is 64K (the maximum size it can support is 64MB), but you should increase the message size if you need to use streaming mode and transfer large amounts of data. This is how you can configure the message size in the service configuration file.
Can you use WCF functions when streaming is enabled?
You can’t use a significant number of WCF features when streaming is enabled: Digital signatures for the message body can’t be performed because they require computing a hash over the entire message content. The encryption relies on digital signatures to verify that the data has been correctly reconstructed.
How does security work on a WCF server?
Note that you can protect the communication between your WCF service and the client using either Transport Security or Message Security. While the former is used to enforce security at the transport level, the latter is used to encrypt the message that is passed between the WCF server and the client.
Why do large amounts of data need transmission mode?
Processing large amounts of data requires a large buffer and lots of available memory on both the client and server sides, therefore you should use streaming mode, which improves the scalability of the service, as you don’t need have large memory buffers to store data.
What are the two WCF transfer modes?
Provides support for two data transfer modes: buffered mode and transmitted mode. While in buffered mode (this is the default mode supported by WCF), the data is buffered in its entirety until the data transfer is complete.
What is the best way to transfer data?
WCF (Windows Communication Foundation) is a secure, reliable and scalable messaging platform for developing services on .Net. Provides support for two data transfer modes: buffered mode and transmitted mode.
