SIMD at System.Numerics.Vectors: Could not load type 'System.Numerics.Vector`1'

[cheers00]

Hi,
I wanted to try SIMD after reading the article at http://blogs.microsoft.co.il/sasha/2014/04/22/c-vectorization-microsoft-bcl-simd/ and I am getting the following error.

{"Could not load type 'System.Numerics.Vector`1' from assembly 'System.Numerics.Vectors, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.":"System.Numerics.Vector`1"}

I am using VS 15 CTP6 and the project is set to x64.

I've added the package using Nuget manager.

<package id="System.Numerics.Vectors" version="1.1.6-beta" targetFramework="net45" />

I can build without any problem but at execution I get the above exception. I can not also step-into MinMax vector function.

Wondering if I am missing any settings.

            for (int i = 0; i < a.Length; ++i)
            {
                min = Math.Min(min, a[i]);
                max = Math.Max(max, a[i]);
            }
            minimum = min;
            maximum = max;
        }

I think this is related to #13947

@mellinoe Can you take a look?

[mellinoe]

Unfortunately, this is going to be broken on preview versions of VS 2015 and the .NET 4.6 preview right now. In the meantime, I believe (not 100% sure) that it is possible to build the library yourself from source and use it, as long as the one you build yourself has a sufficiently high version number. When we release the final version of .NET 4.6, we will have a much better story for using the library, but in the current preview versions, it is not good, unfortunately :(

@mellinoe This is still broken in VS 2015 RC.

[mellinoe]

This should be fully addressed in 2015 RTM, or rather with 4.6 RTM installed. Let me know if there are any lingering incompatibilities.
