I have a very old application developed in Delphi C++. It has an api for which it has access to it. The application has given a sample source code in which there is a windows application which uses this api using Windows messaging system which is RegisterWindowMessage. Now I would like to create a interface to a silverlight. I have presently thought of exposing the data as a service using WCF and consume it in Silverlight. Is it possible or is there any other alternate solution to it? Kindly give me a suggestion as I am a newbie.
A:
You will need to communicate via WCF or better still WCF RIA Services as Silverlight's security model won't allow you to communicate directly with another application on the client's computer.

There's a possiblity you could use the COM interop in Silverlight 4 to work with the desktop app in that way.
