What is WCF and how is it different from ASMX web services?

WCF, or Windows Communication Foundation, is a framework for building service-oriented applications in Microsoft .NET. It provides a unified programming model for building distributed applications.

One of the key differences between WCF and ASMX web services is that WCF supports multiple protocols and message formats, whereas ASMX web services are limited to HTTP protocol and XML message format. WCF also offers better support for creating secure and reliable services through features such as message encryption and transactions.

Overall, WCF is a more flexible and powerful framework for building distributed applications compared to ASMX web services.
