When including any managed class to my managed unit test the compile spits out these errors:
1>UnitTest.obj : error LNK2020: unresolved token (0A000360) "extern "C" int __cdecl _CrtDbgReportW(int,wchar_t const *,int,wchar_t const *,wchar_t const *,...)" (?_CrtDbgReportW@@$$J0YAHHPB_WH00ZZ)

I am using a clr project as well as including a managed class. Removing the include allows the test to compile.
回答1:
To solve this issue you must remove
"_DEBUG"
from the test project in
[TestProject] -> Properties -> C/C++ --> Preprocessor --> Preprocessor Definitions
Alternitively you can change
"_DEBUG" to "NDEBUG"
