working with multiple app domains

[sreekanth]

I have this interesting problem. I am creating multiple domains using AppDomain.ExecuteAssembly. I created domains App1, App2 and App3 (in the same order). If I close App1, both App2 and App3 close immediately. If you close App2, it will close App3 but not App1. It won't affect App1 and App2 if I close App3. I think they are kind of having parent-child relation. I wonder how to avoid this. I want to close only A, not B and C.


Thanks in advance.

private int i = 0;

private void button1_Click(object sender, EventArgs e)
{
MethodInvoker m = (MethodInvoker)delegate()
{
Evidence ev1 = AppDomain.CurrentDomain.Evidence;

AppDomainSetup domaininfo = new AppDomainSetup();
string appPath = Application.ExecutablePath;

i++;
string appName = "App" + i.ToString();

domaininfo.ApplicationName = appName;
domaininfo.ApplicationBase = "file:///" + System.Environment.CurrentDirectory;

AppDomain d = AppDomain.CreateDomain(appName, ev1, domaininfo);
d.InitializeLifetimeService();

d.ExecuteAssembly(@"C:\projects\WindowsApplication 2\bin\Debug\WindowsApplication2.exe");
MessageBox.Show("Closing " + appName);
};
this.BeginInvoke(m);
}
