How will I use the SignInManager with the ElasticScaleContext?

Hi there

My question is will these tools work with IdentyCore? How can I use the ElasticScaleContext with the SignInManager?

In the example given below, blogs are being fetched for a specific tenant:

```
SqlDatabaseUtils.SqlRetryPolicy.ExecuteAction(() =>
{
using (var db = new ElasticScaleContext(sharding.ShardMap, s_tenantId2, connStrBldr.ConnectionString))
{
// Display all Blogs from the database
var query = from b in db.Blogs
orderby b.Name
select b;

Console.WriteLine("All blogs for tenant id {0}:", s_tenantId2);
foreach (var item in query)
{
Console.WriteLine(item.Name);
}
}
});
```
How will use the SignInManager to check whether the user is authentic or not?
