Issues using the Entra ID authentication scaffolder

[danroth27]

If I try to use the Entra ID authentication scaffolder when I'm logged in using my Microsoft organization account, the dotnet scaffold tool will take a long time during the "Discovering scaffolders" step, about 5min. The discovery step eventually seems to time out and then only the Aspire scaffolder is displayed. None of the other ASP.NET Core scaffolders including the Entra ID scaffolder show up. I believe this is a manifestation of #3279.

If I instead login with my personal Azure subscription, it seems to work around this problem and the ASP.NET Core & Entra ID scaffolders do show up.

But now if I select the Entra ID scaffolder, I'm asked to make from a very long list of usernames that all appear to be the same:

But none of these users are from my personal Azure subscription, so I'm not sure why they show up here.

If I just pick the first username and select that I want to create a new app registration I get asked to pick from a similarly long list of indistinguishable tenants. If I just pick the first tenant, I get stuck waiting on this Create or Select Application screen:

After waiting a long time, I get this connection aborted error from the Azure CLI:

I was able to get around the Entra ID scaffolder choking on my org subscriptions by logging out explicitly from my org account (az logout --username [username]). Now when I try to create a new app registration I hit this:

If I try to use an existing app registration, I get a similar error:

I also occasionally see the ASP.NET Core and Entra ID scaffolders just disappear when I run dotnet scaffold even when discovery the scaffolders doesn't take a long time.
