#6781 HI ,

I explain you my architecture as below
I want to develop Multi-tenant – multi databases: One database for the host (master) and separate databases for each tenant.
We can have a HostDbContext (contains only host side entities) and a TenantDbContext (contains only tenant side entities).

Previously I developed one OData service and its working fine but after up gradation with 0.9.7 version I faced a lot of issues.Below is List

1) major Issue is when I want to add TenantDB context in Entity framework then below error occurs

"Found more than one concrete type for given DbContext Type" I resolved this issue with the help of the previous issue.(#1097) Means this issue is not resolved in 0.9.7 version

2) When I try to get Customer Data using OData Service below Exception Occurs
{
"message": "An error has occurred.",
"exceptionMessage": "Could not find a public constructor for type ~Base`1[~.Customer].\r\nWindsor by default cannot instantiate types that don't expose public constructors.\r\nTo expose the type as a service add public constructor, or use custom component activator.",
"exceptionType": "Castle.MicroKernel.ComponentActivator.ComponentActivatorException",

}

A customer is my tenant Entity and I want to access this entity with the help of _unitOfWorkManager.Current.SetTenantId(tenantId)

3) In UserApp and Notification service, I face below issue

//Notifications
await _notificationSubscriptionManager.SubscribeToAllAvailableNotificationsAsync(user.TenantId, user.Id);
I had Changed this call to as below
Abp.UserIdentifier UserIdentifier = new UserIdentifier(user.TenantId, user.Id);
await _notificationSubscriptionManager.SubscribeToAllAvailableNotificationsAsync(UserIdentifier);

So it's written is Correct ? or any other changes is here?

4) AppNotifier.cs below two methods I face issue
public async Task WelcomeToTheApplicationAsync(User user)
{
await _notificationPublisher.PublishAsync(
AppNotificationNames.WelcomeToTheApplication,
new MessageNotificationData(L("WelcomeToTheApplicationNotificationMessage")),
severity: NotificationSeverity.Success,
userIds: new[] { user.Id }
);
}

public async Task SendMessageAsync(long userId, string message, NotificationSeverity severity = NotificationSeverity.Info)
{
await _notificationPublisher.PublishAsync(
"App.SimpleMessage",
new MessageNotificationData(message),
severity: severity,
userIds: new[] { userId }
);
}

How I can resolved this Issue .
