First a terminology correction. The word you are looking for is "proprietary", not "commercial". Open source software is commercial in every sense of the word. It is created by businesses, sold to businesses, used by businesses. This is true in practice and was so recognized by the courts in a important legal case.
As for the license you are asking about, go to http://www.opensource.org/licenses/ms-pl.html and read the text. (Note that the license was created by Microsoft for use in software written by Microsoft - which is not known as a charity. That is commercial software.) Reading section 3d it is within the rights granted by the license to distribute a compiled binary including that software, however you have to abide by the terms of the software. So, for instance, you can't use the contributor's name, logo, etc for your software. (Odds are that the contributor is Microsoft.) It should be very easy to to comply with that license. But if you are in serious doubt about whether you are complying, consult with a lawyer.
