c# - Static Variables in WCF

Question

I have some WCF services. These services run in ASP.NET. I want these services to be able to access a static variable. My problem is, I'm not sure where the appropriate server level storage mechanism is. I don't want to use the database because of speed. But, I want the static variables to stay in memory as long as possible. In fact, I'd like it to stay until I restart my server if it all possible.

Can anyone provide me with any ideas?

Answer 1

You could use static variables in WCF but you must properly synchronize the access to them because they can potentially be accessed from multiple threads concurrently. The values stored in static variables are accessible from everywhere in the AppDomain and remain in memory until the server is restarted.
