HasName() throws System.StackOverflowException

[HSchwichtenberg]

HasName() is marked "obsolete", but should not result in

System.StackOverflowException
HResult=0x800703E9
Message=Exception of type 'System.StackOverflowException' was thrown.

Steps to reproduce

protected override void OnModelCreating(ModelBuilder mb)
{
mb.Entity().HasIndex(x => x.FreeSeats).HasName("Index_FreeSeats");
}

Not happening if I use HasDatabaseName()

Further technical details

EF Core version: 5.0 Preview 7
Database provider: Microsoft.EntityFrameworkCore.SqlServer
Target framework: .NET 5.0 Preview 6 und 7
Operating system: Windows 10
IDE: Visual Studio 2019 16.6

This stack overflow comes after add-migration xxx?

I wanted to upgrade preview 6 to 7, but I got Stack overflow after add-migration in preview 7...

BTW I didn't have any obsolete mark for HasName() in my configurations while I was in preview 7

@dotnet/efcore This is a bad obsoletion; see below. Do we think this impact many existing migrations? If so we might want to fix it for preview 8.

[Obsolete("Use HasDatabaseName() instead.")]
public static IndexBuilder<TEntity> HasName<TEntity>([NotNull] this IndexBuilder<TEntity> indexBuilder, [CanBeNull] string name)
    => indexBuilder.HasName(name);
