Static linking requires additional runtime libraries to be linked as well. You can find the list of all required libraries by publishing the project as shared library (/p:NativeLib=Shared) with detailed verbosity (-v d), and looking at the output generated by the LinkNative target.

We have #70277 opened on improving this experience.

Everything works. Thank you. But there was another problem. When adding #include iostream, compilation errors appear. Without using this "#include", compilation completes without errors.

Before applying #include iostream:

Sorry. I have solved the problem. I set the "Multithreaded /MT" setting in "code generation" and added "#pragma comment(lib, "libcmt.lib")".
