7. Microsoft.Bcl.Simd
Modern processors can issue 4-8 integer/fp
operations per cycle; RyuJIT supports it
int ArithmeticSeriesSumSimd(int n) {
Vector4f vsums = new Vector4f(0, 0, 0, 0);
Vector4f viter = new Vector4f(1, 2, 3, 4);
Vector4f vstep = new Vector4f(4, 4, 4, 4);
for (int i = 1; i <= n / 4; ++i) {
vsums = vsums + viter; // ADDPS
viter = viter + vstep; // ADDPS
}
return (int)(vsums.W + vsums.X + vsums.Y + vsums.Z);
}

8. Roslyn and C# 6.0
Roslyn is coming, in the meantime many new
C# 6.0 features were publicly revealed
And Roslyn went open source!
var salaries = new Dictionary<string, int> {
["Kate"] = 1200,
["Dave"] = 1100
};
if (int.TryParse(1700, out var result)) {
Console.WriteLine(result);
}
customer?.Address?.AddressLine[0]?.Print();

9. More C# 6.0 Features
using System.Math;
class Point(int x, int y) {
public int X { get; set; } = x;
public int Y { get; set; } = y;
public double Magnitude => Sqrt(X*X + Y*Y);
}
try {
Parallel.ForEach(...);
} catch (AggregateException ex) if (ex.Count > 1) {

{
decltype(terms) results;
for (auto term : terms)
{
auto translated = await translate_async(term);
results.push_back(translated ? translated : "N/A"s);
}
parallel_sort(results.begin(), results.end());
return results;
