Delphi compilers with support for the inline directive (starting with Delphi 2005) failed to compile DIContainers *.bpl packages for the Demo and Commercial editions. They generated a “[dcc32 Fatal Error] DIUtils: F2051 Unit DIContainers was compiled with a different version of DIUtils.StrSameIW”. Regular *.exe applications compiled without problems. The DIContainers Source Code also compiled to both *.bpl packages and *.exe applications with no problems.
