I followed these step to deploy Asp.net Core 2.0 Web Api Code First to Local IIS.

after created an Asp.net Core 2.0 Web Api Code First (DB)

I did the following:

1) Install Microsoft.Net core 2.0.6-windows server Hosting

2) Create a Folder with name below in C-drive for Publishing the WebApi Project 

   C:\PublishedTestCoreWebApi\CoreWebApiTest1

3) Launch IIS (with inetmgr) in local PC

3.1) create an Application Pool with following info:

Name: NoManagedCodePoolTest1
.NET CLR version : No Managed Code
Managed pipeline mode: Integrated

3.2) Create a website in IIS with these info:

sitename : myAspCoreWebApi 
Application pool : NoManagedCodePoolTest1
Physical path:  C:\PublishedTestCoreWebApi\CoreWebApiTest1
Binding:
Type: http
IPAddress : (use the local IpAddr like: 192.168.x.x)
Port : 8383
Host name : leave it blank

2.3) Check the Website created contains AspNetCoreMudule: Yes.


3) Open TCP Port: 8383 on Firewall for the Website

4) configure SQL Server
There is only one Sqlserver in PC with its name :Sql2017Express ( so this is named instance)

4b) Configure Port 49xxx for SQL Server thru SQL Server Configuration manager with the settings:
