>I haven't used it myself, but this post indicates support for UDFs was added to Code First in 6.1.1: http://blog.3d-logic.com/2014/08/11/the-beta-version-of-store-functions-for-entityframework-6-1-1-code-first-available/. The article is discussing the beta version though, so its possible that it was removed in the RTM version.

Thanks, Rob. According to this article http://blog.3d-logic.com/2014/10/18/the-final-version-of-the-store-functions-for-entityframework-6-1-1-code-first-convention-released/ it seems to be released. I'm going to email to my colleagues to see if we can switch to 6.1.1 (We're using 6.0.0 right now).
