C ++ / CLI: Build a static library with / CLR support

We have old (working) code which consists of a static library compiled with / CLR and a C ++ / CLI DLL that references the static lib. We are going to add new functions to this static library.

Now, I have heard from numerous sources that static CLR libraries are not supported by Microsoft, and so I am trying to clean this up and switch to DLLs before we start adding new functionality to this project. However, I could not find any official information from Microsoft regarding this (say from MSDN - other than their forums).

I will be grateful for any resources on this whole "static lib with CLR" issue.
