ERROR AFTER UPDATING _layout.cshtml navbar

Copper Contributor

Hello guys. I have problem in my MVC code _layout.cshtml. whenever I add new code an internal server error occurs. But when I remove the code, the program runs properly. I tried adding the bootstrap nuget package and popper.js, but nothing is changing. The commented code is the one that is bringing the internal server error after removing the comment.


what could be the problem? please help
