Blazor authentication with multiple claims sources

[wiwichu]

Hi,

This is a follow-up to #28362, which has been closed.

I have actually set up an IDP (Identity Provider) and am able to authenticate, but what I want to do is after getting claims from the IDP, make a call to the app's API and get more app specific claims to merge with those from the IDP. This approach is described in a Pluralsight course by Kevin Dockx https://app.pluralsight.com/library/courses/dealing-credentials-when-securing-aspdotnet-core-3-application/table-of-contents. It uses Microsoft.AspNetCore.Authentication.OpenIdConnect, but the client is not Blazor. Do you know how I might implement this approach with a Blazor client?

Thanks,

Patrick
