asp.net – blog code

Add Website and created folder eg . c:\iis\myapi
Change Application Pool to No Managed Code
Check Security of Folder, add
- IIS_IUSRS
- IIS AppPool\myapi
Browse Created Website (should result in HTTP Error 403.14 – Forbidden to list contents cause nothing is in)
Create new repo eg github
Create new VisualStudio ASP.NET Core API
Run and Debug
try api endpoints
publish to target Folder (best case: separate folder to copy after publish)
Copy contents (using TeraCopy eg , resp. diff sync tool)
try sampleendpoint
- take care that Swagger is not configured to show in default so dont despair
commit your state if working
checking git status is everything is correctly tracked.
rename WeatherForecast to dream name best with eg. Notepad++ replace all and change files names in VS later on.
test run and debug
publish again
test it on local IIS.

works till here. so integrate biz logic and repeat small steps cycle step by step.

Next steps if resolved: test from different computer, intranet:

connect to ip host and port
if connection is not working through, check firewall rules.
go to advanced settings
open up required port by adding Inbout Rule Port
test api from network computer
add /swagger , respectively the desired endpoint to url
