So this is an odd one.

It seems that this is a newly introduced problem/bug with Delphi Prism 2011, as the same code compiles without error on Prism 2010.

I was eventually able to identify the offending code; the issue is with with some legacy code that relies heavily on the use of sets.

I've created a crappy work around that keeps me moving; but for the interested, here's how to simply and quickly re-create this problem:

1. Create 2 assemblies using the class template in VS (2008 or 2010).

2. In each assembly add the followings declarations:
a) in assembly1 - add the following
Type
enum1 = public enum(abc, def, ghi);
set1 = public set of enum1;
compile and create the assembly.
b) in assembly2 - add the following
Type
enum2 = public enum(jkl, mno, pqr);
set2 = public set of enum2;
compile and create the assembly.

3) Now using the VS template create a 3rd assembly and add the following
Type
enum3 = public enum(stu, vwx, yz);
set3 = public set of enum3;
Now add, Assembly1 and Assembly2 as references in the Assembly 3 project.

When you (or when I) try build Assembly 3; I get the folllowing compilation/build error:
Error
1
(CE73) Type "<PublicImplementationDetails>" used is defined in multiple assemblies (Assembly1, Assembly2)
C:\Program Files (x86)\MSBuild\RemObjects Software\Oxygene\RemObjects.Oxygene.targets
167
5
Assembly3

I am not happy with my workaround; I moved all the set and enum declarations into a single assembly and it now builds without an issue but this is not desirable so I'd really like to get some help on how to better move forward.
