WCF services for OCR, barcode, image conversion and processing.
Window Communication Foundation Services (WCF) provides the .NET Framework with a basis for writing code to communicate across components, applications, and systems. WCF was designed according to the tenets of service orientation. A service is a piece of code you interact with through messages. Services are passive. They wait for incoming messages before doing any work. Clients are the initiators. Clients send messages to services to request work.
WCF services may be accessed via several protocols including HTTP, TCP, IPC and MSMQ. Depending on how you want to access the services, they may be hosted in IIS, Window Activation Service or any .NET managed application process including console, Win Forms, WPF, Silverlight and Windows service applications.
