Does anyone know of a free package that will solve quadratic programming problems in C#?
I've googled and found a few. But it's hard to tell which is the best and fastest. Does anyone have a favorite?

The standard form of a quadratic equation is: ax2 + bx + c = 0, where a, b and c are real numbers and a != 0. The term b2; - 4ac is known as the discriminant of a quadratic equation. It tells the nature of the roots. If the discriminant is greater than 0 , the roots are real and different.
A quadratic programming (QP) problem has a quadratic cost function and linear constraints. Such problems are encountered in many real-world applications. In addition, many general nonlinear programming algorithms require solution of a quadratic programming subproblem at each iteration. As seen in Eqs.
C-value - also called the y-intercept of the parabola, this is where the x-value is zero, and graphically, this is where the graph intersects the y-axis.
ALGLIB is a great library with both free (GPL) and commercial licenses available. It has good documentation and offers a number of optimization algorithms.

Perhaps the MS Solver Foundations?
