You can try it as shown below using Fluent API.

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{

    modelBuilder.Entity()
                .HasMany(s => s.Users)
                .WithMany(c => c.Tasks)
                .Map(cs =>
                        {
                            cs.MapLeftKey("TaskRefId");
                            cs.MapRightKey("ApplicationUserRefId");
                            cs.ToTable("TaskApplicationUser");
                        });

}
