Link against the Boost.Thread DLL. Build your app with BOOST_THREAD_USE_DLL defined to force the auto-link to choose this, and ensure that the code is compatible.
Many thanks for taking time to clarify the issue. Defining BOOST_THREAD_USE_DLL in the mini demo project helps. (Only ilmerge fails to merge the C++/CLI DLL with the C# executable ...) Alas, for the RealWorld example containing some more spirit parser code this does not help either. The linker now correctly chooses the DLL: Linking...

Any further idea? Am I not allowed to mix the static inclusion of date_time with the dynamic version of threads? I also tried BOOST_DYN_LINK, but even then libboost_date_time-vc90-mt-1_37.lib ist used by the linker. Then used BOOST_DATE_TIME_DYN_LINK which should have the same effect, but then linking chooses the correct libs: Searching libraries [...] Searching D:\FEV-Data\Sourcen\FEV\TOPexpert\3rdParty\BOOST\boost_1_37_0 \stage\lib\boost_thread-vc90-mt-1_37.lib: Searching D:\FEV-Data\Sourcen\FEV\TOPexpert\3rdParty\BOOST\boost_1_37_0 \stage\lib\boost_date_time-vc90-mt-1_37.lib: This looks odd to me. Ain't this a bug for DATE_TIME? Anyway, even then System.BadImageFormatException is thrown. I am lost again. regards, Markus
