I just read a very cool NHibernate trick to let your application start faster that was mentioned by Ricardo Peres:
Configuration cfg = new Configuration().Configure();
IFormatter serializer = new BinaryFormatter();
using (Stream stream = File.OpenWrite("Configuration.serialized"))
{
serializer.Serialize(stream, cfg);
}
...
using (Stream stream = File.OpenRead("Configuration.serialized"))
{
cfg = serializer.Deserialize(stream) as Configuration;
}
