Initialize 0.2.4

Overview

High performance automatic DTO mapper and properties initializer based on Roslyn dynamic code and compilation

Example Usage

	var test = new Test();
	var test2 = new Test2();

	// INITIALIZER EXAMPLE
	test.Dump("Test Pre Init");

	// 1.Optional If you want to manipuate the default initialization logic.
	Initializer<Test>.Template.Clear();

	Initializer<Test>.Template.Add(typeof(string),
		(obj, propInfo) => "string.Empty");
	Initializer<Test>.Template.Add(typeof(Nullable<>),
		(obj, propInfo) => string.Format("{0}.{1}!.InitValueOrDefault()", obj, propInfo.Name));
	Initializer<Test>.Template.Add(typeof(ValueType),
		(obj, propInfo) => string.Format("{0}.{1}.InitValueOrDefault()", obj, propInfo.Name));
		
	// 2. Call initialize 
	Initializer<Test>.Initialize(test);
	test.Dump("Test Post Init");
	

	//MAPPER EXAMPLE
	test2.Dump("Test2 Pre Map");
	Mapper<Test, Test2>.Map(test, test2);
	test2.Dump("Test2 Post Map");

Mapper Benchmarks

Initializer's Mapper is roughly 4x faster than AutoMapper...
