asp.net 6 React User.Identity.Name

Question

We are migrating to React .net 6 from 5. Our apps are internal and we use windows authentication. No issue with this in previous versions getting user.identity.name in a controller with react. I understand the dev environment is working differently. I and another programmer have blogged this issue for a day now and tried many things but are at a point that we cannot get user.identity.name to work in a controller. So could someone give me exact directions on adding this line "var userName = User.Identity.Name" in the Get method on the WeatherForecastController in the default React Template in VS 2022 actually returning something other then null. Thanks .

Answer 1

I don't believe it is supported in developer mode. when you run dev mode, the .net 6 app starts a node express web server (actually just npm start which does it) to host the react code. the node web server does a reverse proxy to the net 6 webapi server.

the node express server does not support windows identity.

if you do publish to IIS and configure windows identity it should work.

note: this is reverse of .net 5, in which the spa services reverse proxied to the node server. this why windows identity works in .net 5 projects.
