this is my contextDB

namespace Cadcc.Data {
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{

private readonly AppTenant tenant;

public ApplicationDbContext(AppTenant tenant)
{
this.tenant = tenant;
Database.EnsureCreated();
}


protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseNpgsql(tenant.ConnectionString);
base.OnConfiguring(optionsBuilder);
}


protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
// Customize the ASP.NET Identity model and override the defaults if needed.
// For example, you can rename the ASP.NET Identity table names and more.
// Add your customizations after calling base.OnModelCreating(builder);
}

//adding a model for Oportunity

}

}
