OpenBLAS.NET
OpenBLAS.NET is a CSharp binding of OpenBLAS library: https://www.openblas.net/
In scientific computing, OpenBLAS is an open source implementation of the BLAS (Basic Linear Algebra Subprograms) API with many hand-crafted optimizations for specific processor types. It is developed at the Lab of Parallel Software and Computational Science, ISCAS.

Example Dot Operation
static Array Dot(float[,] a, float[,] b, float alpha, float beta)
{
unsafe
{
int m = 2;
int k = 3;
int n = 2;
int lda = 2;
int ldb = 3;
int ldc = 2;
float[,] c = new float[m, n];
sbyte nta = (sbyte)BlasOp.NonTranspose;
BLAS.Sgemm(&nta, &nta, ref m, ref n, ref k, ref alpha, ref a[0, 0], ref lda, ref b[0, 0], ref ldb, ref beta, ref c[0, 0], ref ldc);
return c;
}
}Invoke the function:
static void Main(string[] args)
{
int num_threads = 2;
BLAS.OpenblasSetNumThreads(ref num_threads);
float[,] a = new float[,] { { 1, 2 }, { 3, 4 }, { 5, 6 } };
float[,] b = new float[,] { { 2, 2, 2}, { 3, 3, 3 } };
var c = Dot(a, b, 1, 0);
Console.ReadLine();
