The type '…' exists in both 'Util.dll" and 'Util (Silverlight).dll'

Question

I'm attempting to follow David Betz' wonderful advice on how to use a library project in both your .NET and Silverlight code. In particular, I'm using his File-Level technique: I have a .NET library project already set up, so I created a Silverlight project, and added links in the latter to the former's files.

Unfortunately, there is a problem. I get compilation errors like crazy, of the form:

The type '...' exists in both 'Util.dll' and 'Util (Silverlight).dll'

In all of my other projects, I only reference one or the other. Neither Util dll has a reference to the other, so I'm not sure why the compiler can see both DLLs from any of the other projects.

Any ideas?

Argh! It really was this simple :) I just fixed the compilation issues other then this one, and it suddenly stopped complaining.

I also added to the linked projects Project Dependencies on the real projects, and that helped keep the errors more consistent, at least.
