Sorry, my mistake - that trick only actually works if you're inside the MathNet.Numerics.LinearAlgebra namespace. Please consider cuda's approach instead with an alias, or more general e.g.:

using DoubleLA = MathNet.Numerics.LinearAlgebra.Double;
using ComplexLA = MathNet.Numerics.LinearAlgebra.Complex;

var a = new DoubleLA.DenseMatrix(3,4);

Thanks,
Christoph
