🌐PerigeeApplication

Application initialization

Both application starting points are nearly identical. The full callback has an IPC token and the initialize callback. Both are described in Hello Perigee.

Application(string appName, string IPCCancelToken, Action<IConfiguration> initialize, Action<ThreadRegistry> taskConfiguration, CancellationTokenSource cancelSource = null, Task HostTask = null, string[] CommandLineArguments = null)
ApplicationNoInit(string appName, Action<ThreadRegistry> taskConfiguration, CancellationTokenSource cancelSource = null, Task HostTask = null, string[] CommandLineArguments = null)

You may also run the ApplicationNoInit as an async method as well:

PerigeeApplication.ApplicationNoInit("async", async (c) => { 
    await Task.Delay(1000);
});

Initialize outside a PerigeeApplication

Sometimes you need to initialize outside of the scope of a PerigeeApplication. We do this for API applications, blazor applications, and other scenarios where we need to call something before Perigee.

static void Main(string[] args) {

   //To initialize perigee and the thread system:
   ThreadRegistry tr = ThreadRegistry.InstanceWithArgs(args);
   
   
   //Initializing credentials is not usually required unless changing working directories.
   //If you must initialize them, use either A or B:
   
   //A) Call instance
   var cinstance = CredentialStore.Instance;
   
   //B) Congiure
   CredentialStore.Configure()
}

Host Statistics

To get information about the host it's running on, there is a single method:

GetHostStatistics()

The response class, HostStatistics contains properties for the machine it's running on including machine name, drive info, cpu time and running directory.

Exit event

To get an exit callback, use the helper method supplied.

After return is executed and the domain/service is about to unload, OnExit has a few seconds to perform any last tasks, like persisting data.

static void Main(string[] args)
{
    PerigeeApplication.OnExit(() => {
        Console.WriteLine("Exiting");
    });

    return;
}
