New Post: MIT on top of LGPL

Although Wix# is licensed as MIT, I have noticed that you are using MsiInterop.cs which is licensed as GNU Lesser License V2.1. Does this mean that embedding the WixSharp.Msi dll in an installer for commercial distribution (like your WpfSetup sample), violates the terms of the LGPL? Also, it is at all legal to license your work MIT while it has some LGPL code inside?

Thanks a lot for your answer!
