try it with fluentAPI
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<IdeaViewModel>()
.HasOne(i => i.User)
.WithMany()
.HasForeignKey("UserId")
.HasConstraintName("FK_IdeaViewModel_User");
base.OnModelCreating(modelBuilder);
}

The Column is still Id :thinkHeadSideWaysCutePondering:
You need to explicitly define a foreign key property in addition to your navigation property
just noticed
[Column("UserId")]
public string UserId { get; set; } = null!; // this one
[ForeignKey(nameof(UserId))]
public virtual ApplicationUser? User { get; set; }
[Column("UserId")]
public string UserId { get; set; } = null!; // this one
[ForeignKey(nameof(UserId))]
public virtual ApplicationUser? User { get; set; }
