如何在本地 IIS 中部署 WebAPI 项目

Question

I have created a WebApi project with EF6,it is working good in local. I have published in local IIS. But I am getting " HTTP Error 404.0 - Not Found " error after publishing

I am using VS2015 and IIS7.5 . Am I missing something. Below is the code.

Answer 1

Have you created an application pool & mapped the website to that pool?

Allocated the port of the website to 80?
