Yes, but our copyright/license text must be included visibly with your application. See also the actual MIT/X11 license text. An in-app about/info tab as most apps have these days would be a good place, and mentioning the dependency on "Math.NET Numerics (MIT/X11)" in the marketplace description would be nice.

NOTE: This only applies to Math.NET Numerics, not to other Math.NET libraries (e.g. Symbolics): Most of the other non-Numerics projects use more restrictive license terms like the GPL. If a library is available only under the terms of the GPL, then it can NOT be used in a closed source WP7 application. However, Math.NET Numerics does not depend on any other Math.NET project or any other code with copyleft-clauses, so you're safe to use it in closed source proprietary applications.
