Deep dive tutorial 🎉 thanks efforts dude

[brankogojkovic]

Awesome, thanks a lot. It would be nice if there was a video for another example as well (Build a Multi-Tenant App With Multiple Databases)

Great stuff - if we can see how to do this using Identity for the authentication, sign up, etc., if would make this thing AWSOME!

6:21 SQLServer is way slower working with a string as a primary key instead of an int.

[joga_bonito_aro]

ngl... that second DBContext feels like a hack.

[nwoivny]

Does this integrate with Azure AD (Entra ID) tenants?

[SOYLUISO]

good video, but that part of creating a second db context only for resolving the tenant of the request is pretty ugly to be honest.

[umairmalpara]

This is good. But it can be hectic if we have lots of tenants. Can we extend this example to store tenant data in different schemas of the same database? And How?

[FelipeAlmeida-bckf]

first off all thks a lot for these tutorial...
i have just one question:
when i tried to POST a new product, an was thrown saying that it can't insert a NULL value to TenantId Column, on Product table....
Should we add this information ( by claims for example) on Create endpoint/service?
i watched your tutorial twice and could not find any diferences on our code...
thanks alot!!!!

[ghevisartor]

nice video! how do you prevent another tenant to use the key of someone else? are they supposed to be very difficult to find or is this a non issue?

[LordErnie]

Here is me, asking myself what the fk is a Tenant. Good vid non the less tho.
