LNK2028, LNK2019 without extern "C"

I wrote a Win32 dll in VS2005 and a CLR-Console client, the CLR-Console client is the caller of Win32 dll. In the Win32 dll, using /TC compiler option to build it and using /clr option to build the CLR-Console client. The all things is fine, such as 'dllexport/dllimport', 'Additional Include Deirectories' and 'Additional Dependencies'. But I got LNK2028 unresolved token and LNK2019 unresolved external symbol, the reason is I forgot using the extern "C" to include all dllexport functions.
