Implement WCF sample

[constructor-igor]

Requirements:

• [x] inter-process communication
• [x] callback (subscribe)
• [x] TCP/IP
• [x] without reference
• [x] .NET 4.5 and above

Suggested architecture:

• [Shavuot.Contract] Project with definitions (interfaces, contracts, etc,).
• [Shavuot.Service] Project with service implementation (cannot be started).
• [Shavuot.ServiceHostingApp] Project (console application) for service hosting (self-hosting).
• [Shavuot.Client] Project "client" (console application): user types messages and client "sends" them to service.
• [Shavuot.Viewer] Project "viewer" (console application): shows messages, received from "service".

Code: https://github.com/constructor-igor/TechSugar/tree/master/WCF/Shavuot

Issues:

• Client requires definition of CallBack? (client doesn't use callback)
• Lifetime of service (seems, after 1 hour of idle time, connection is broken
• if browser should open http://localhost:8888/shavuotservice?
