    Creating new AppDomains...how many is too many???

    Hi,

    I need to create seperate AppDomains to dynamically load assemblies.
    But...how many AppDomains is too many?

    Is it ok to create 100? Is 1000 too many???
    I am trying to work out what the overhead would be if my client app created 100 new AppDomains, one for each dynamic assembly.

    Cheers,

    Wojka

    Re: Creating new AppDomains...how many is too many???

    For a 24/7 running service mining data of a pharmacy-system, sending it to the "head quarter" I ran into a bug in the .Net framework where, on some systems the service had a memoryleak. Doing the sending (with WCF) in a separate appdomain for each message. This means the services create about 3.000 appdomains per day, giving a overhead of 30 seconds processortime per day.
    According to this link from MSDN running a lot at the same time time isn't gonna be a problem
    VB6 & C# (WCF LINQ) mostly


    If you need help with a WPF/WCF question post in the NEW WPF & WCF forum and we will try help the best we can
