The current visual studio (2017) doesn't have the option to add individual authentication locally. It allows that feature only for it's Azure cloud offering. I also checked in visual studio preview 2019 and the 'individual authentication' using Identity server is not provided locally but provided for Azure platform.

Check this stackoverflow link: No individual user accounts auth options in asp.net core web api template

​

I'm developing an app to just run on a desktop computer and don't want to use the Azure platform.

I tried this in cmd console using the .net core sdk: dotnet new webapi -au Individual

And it didn't work either. I checked the packages in the solution explorer and it showed the identity package for Azure.

​

How do I add Identity server to my existing web api?

Do you see Microsoft forcing developers to use it's cloud platform?

Thanks
