How do I share data with .net applications?

[Guest]

I have several .net window form applications. How do share data among them so
that I only have to update data from one application and other applications
will see the changes?

Use a database,

By instance SQL server express, it is free to use

Dear Cor:
My application is very time critical. essentially it processes real-time
stock tic data.
Won't using a database slow down the process?
