Add-Migration hangs on using context - no error

I'm having an issue with my package manager console. I run Add-Migrations name -Verbose and it hangs after finding the database context. Note - this is not my initial migration, that worked fine, this is a new migration. Also, this is a console app, not a web app, so I'm not worried about the error concerning hosting.

I've let this just sit for nearly an hour, nothing happens.

I had the same issue when trying to add a migration after changing the base class from DbContext to IdentityDbContext.

It was due to a mismatch in the references for Microsoft.AspNetCore.Identity.EntityFrameworkCore.

Project was on .Net Core 5 prev 7 but I mistakenly added a reference in NuGet for 3.1.
