TypeInitializationException thrown by aleagpu

I am trying to use aleagpu but I get the System.TypeInitializationException. I have tried to google what the problem is but I couldn't find any solution, so please help. The program is the simplest possible:

class Klazz
private const int N = 100;
private const int Length = 10000000;
var gpu = Gpu.Default;// here is the Exception thrown
public static void Unmanaged()
var data = new int[Length];

for (var k = 0; k < N; k++)
gpu.For(0, data.Length, i => data[i] += 1);

I am imagining that there is something wrong in my installation, because the program is a copied example from aleagpu's homepage.

My system is:

  • Windows 10

  • .NET v4.5.2

  • VS 2015 Community
    NVIDIA GPU computing toolkit CUDA v8.0

Alea is installed from NuGet November 9. 2016

  • Alea (3.0.1)

  • Alea.IL (

  • Alea.CUDA (

  • Alea.CUDA.IL

  • Alea.CUDA.Unbound (

The variables in PATH is correct.

I have tried the AleaSample.CS.ParallelForAutoMemMgt as well with the same result.

It turns out that aleagpu is written in F#, and when you install FSharp.Core the program works. Thanks to Ghosthack answering the question: Alea GPU Tutorial not compiling on VS 2015 Update 2 with FSharp.Core
