SystemH is an attempt to bring the .Net framework to C++, only without the .Net using just C++11 native code. All (ok, 'most') code is well tested, both functionally and for performance. Compared to equivalent .Net code you can expect on average a 10-20% increase in performance, athough in some cases like with System::Collections::Generic::Dictionary it can be over twice as fast.

Simply include the System.h file in your project and start using all your favorite .Net classes like String, Func, Tuple, List, Dictionary, DateTime, Thread and many more. Here's a simple example to get you started, the C# code:

	List<string> lst = new List<string>() { "banana", "apple", "orange", "lemon" };
	List<string> filtered = (from str in lst where str.Contains("a") orderby str select str.Substring(0, 3)).ToList();
	for (int i = 0; i < filtered.Count; i++) {
		Console.WriteLine(filtered[i]);
	}

Which in SystemH becomes:

	List<string> lst = { "banana", "apple", "orange", "lemon" };
	List<string> filtered = lst.Where([](string str) { return str.Contains("a"); }).OrderBy<string>([](string str) { return str; }).Select<string>([](string str) {return str.Substring(0, 3); }).ToList();
	for (int i = 0; i < filtered.Count; i++) {
		Console::WriteLine(filtered[i]);
	}

Note: on ESP32/Arduino you'll need to explicitly activate the integrated memorypool by adding 'UseMemoryPool = true;' in the setup function of your sketch.

Have a nice play!

There is none and I don't plan to write any anytime soon. Check out the tests and the code itself to figure out how everything works.
