Using Parallel Patterns Library (ppl.h)

I'm trying to learn how to use ppl.h in c++ . But I'm not sure what kind of solution I should create in VS2010 to use it. If i create a Win32 Console app without CLR'concurrency' is not recognized and if i create Win32 Console app with CLR i get an error saying

Concurrency Runtime is not supported when compiling /clr.

#include "stdafx.h" #include <ppl.h> using namespace System; void BubbleSort(int* input, int n) { concurrency::parallel_for(0,n,[=](int y) { for(int k = 0; k< n - 1 -y; k++) { if(input[k]> input[k+1]) { auto temp = input[k+1]; input[k+1] = input[k]; input[k] = temp; } } } } int main(array<System::String ^> ^args) { Console::WriteLine(L"Hello World"); return 0; }

You can make a Win32 Console Application (no CLR). Once you #include <ppl.h>, the Concurrency namespace should be available. Note that it's Concurrency::parallel_for (captial "C").

For details, see the PPL example on MSDN.
