title: COM Reference 'XyzLib' is the interop assembly for ActiveX control 'AxXyzLib' but was marked to be linked by the compiler with the /link flag
body: <p>I'm referencing an OCX control written in C++ targeted to native x86 code from a .NET 3.5 C# DLL.  I'm getting this non-critical error message.  Looking for how to get rid of it.  I've searched online but the references I found so far have not been helpful.</p>
  
  <p><em>COM Reference 'SIGPLUSLib' is the interop assembly for ActiveX control 'AxSIGPLUSLib' but was marked to be linked by the compiler with the /link flag. This COM reference will be treated as a reference and will not be linked.</em></p>
  
  <p>I've looked through the properties for both the references <strong>SigPlusLib</strong> and <strong>AxSigPlusLib</strong> but I don't see any place where either of them has been marked to be linked with /link flag.</p>
  
  <p>Links I've looked at to no avail</p>
