Importing Accord.Net

I was working with accord.net both in visual studio and in grasshopper c# and python.

Several functions such as kmeans or linear regression worked well on both.

I am wondering if this really .NET framework issue. 

I have my own compiled libraries in 4.6 and it works within grasshopper scripting components.

Maybe there is very specific issue with net framework or related to C# 7

Hi Petras, thanks for your response. Actually, I realised I was mistaken about the .NET version. It turns out that the .NET framework with which GH is written is the newest. And to be precise, I have to say I have worked with many functions from Accord.NET in GH C# scripts but some namespaces do not import in GH C# component and I get error messages when trying to import the newest versions of Accord.Math.dll in the C# component. May I ask what is the version of Accord you have used successfully and where you downloaded it from?

I am wondering if you have managed to use the magic functionality of accord.net in "understanding" matrices and vectors. That is what I am missing mostly from accord.net in GH C# component: Let's say you declare a multi-dimensional array of doubles and then your c# editor must be able to understand it is potentially a matrix and provide you with the 'extension methods' operating on matrices: 

double[,] matrix =   {{1, 2},{3, 4},{5, 6}};
double[,] nextMatrix=matrix.Multiply(2);//this works in Visual studio but not in GH C#

Hi there,

If any GH developers need any help from the Accord.NET side, please do not hesitate to register this as an issue in the project's issue tracker.
