P>

For example , I will create a DLL with fixed variable and install it on GAC then add to the context of my program.

How can this be done?

Basically you

1. value in storage available from different programs

Use of some process to act on the communication system (referred to by IPC @ S LUX)

which may come to my mind: database, The window registry, the settings file

process process can be WCF, or System.IO.Pipes, or other S:

This is all your requirements And depending on what it is important to perform? Do you need to inform the second process that the price has changed, or the second process will only request the price? How many processes will reach the value at the same time?
