When /EHsc is enabled, the compiled module is not included?

Question

C++ / C#

In general, the essence of the issue is this. I am writing a DLL module for a specific program, inside the module I use standard libraries, which in turn use the throw catch exception model, but when I include it (/EHsc) the module is compiled, but the module is not defined as a module in the target program. How to fix this matter?
