I'm converting a project from vs2008 to vs2010 and getting linker errors for std:ifstream/ofstream

error LNK2001: unresolved external symbol "__declspec(dllimport) public: bool __thiscall std::basic_ofstream<char,struct std::char_traits<char> >::is_open(void)const " (__imp_?is_open@?$basic_ofstream@DU?$char_traits@D@std@@@std@@QBE_NXZ)

Building static (/MT) or dll (/MD) with unicode or standard and release/debug gives the same error. Manually adding libcpmtd.lib (static) or msvcprtd.lib (dll) to the linker doesn't help.

Has anyone else seen this?
