Publishing and hosting Web API developed in .net core through IIS

Question

I have WEB API developed in .net core (VS 2017). I need to deploy this api in IIS. This is the procedure I have followed.

1. Open VS 2017, open the project -> right click on API , click on Publish.
2. Selected File System -> Give a path where binaries where to be placed-> Click on Publish button.

After it is finished, there are some files in the physical path. I have copied the files on to the server where it is supposed to be hosted.

In the server, this is what I have done:

1. Installed .Net core run time.
2. Opened IIS , right click on default website -> Add Application -> Give name of application (say ABC) -> give physical path (where binaries are copied)-> Click OK.

There is a simple Get method in the API for now, where it just returns a string.

Say if the IP address of the server is 10.1.1.1 , this is the URL I'm using.

http://10.1.1.1/ABC/api/GetData

I'm trying this through Postman. I'm getting 500 Internal server error.

When I follow the same process for Web API developed in .Net framework, it is working perfectly fine.

Is there any step which I'm missing for .net core?

You need to ensure the following:

1. .NET core hosting bundle is installed on the server
2. Your application pool .NET CLR version is set to “No Managed Code”
