Visar,
In order to fasten startup time, you can serialize the Configuration
object:
Configuration cfg = new Configuration().Configure();
IFormatter serializer = new BinaryFormatter();
using (Stream stream = File.OpenWrite("Configuration.serialized"))
{
serializer.Serialize(stream, configuration);
}
...
using (Stream stream = File.OpenRead("Configuration.serialized"))
{
cfg = serializer.Deserialize(stream) as Configuration;
}
