Thank you for sharing this video, it is very helpful! I watched two other videos and they missed one important step: update-database. A key step that you showed here, that made my day. Thank you soo much!!!

Thanks for sharing your knowledge, mate! Keep it up!
Btw, Entity Framework is totally removed from our system, it's just too messy and difficult to maintain for all developers. It could work in a very small system but not the enterprise level! Not sure what Microsoft was thinking when they implemented this!

How are you able to run "Add-Migrations" without first running "Enable-Migrations"?

If I try to run "Add-Migrations" I get an error telling me to run EnableMigrations first: ***No migrations configuration type was found in the assembly 'OptionsDataService'. (In Visual Studio you can use the Enable-Migrations command from Package Manager Console to add a migrations configuration).***


And if I try to run Enable-Migrations I get the error: ***No context type was found in the assembly 'OptionsDataService'.***

and then If I try and add a "using System.Data.Entity" to fix that error I get an error saying that I cant have "using System.Data.Entity" and "using at the same time.

And then if I remove "using Microsoft.ENtityFrameworkCore", the entire solution breaks for obvious reasons.

Help.

My Brain is stuck in an infinite loop.

Hi, why don't you make also a playlist about advanced topics on C#, or an entire tutorial on ASP.NET MVC (version 5 or Core)?

Hi,
Thanks for the Video.
I have the problems here, where migrations are running but Database is not getting created. I am getting the message "Applying Migrations..., Done". I am using CLI and command is "dotnet ef database update". Could you please help here..?

respected sir,
can you help us ?


how to create table if table not exists to existing database in ef core ?


we don't use migration because our existing databases are with clients devices and want to create additional tables to their databases after updates for feature extensions...


there was an option like Context.DbEntity.Create(); in ef6 but not getting in ef core to do so...


I used the below but it also not creating tables which doesn't exist...


try
{
var databaseCreator = as RelationalDatabaseCreator);

}
catch (Exception ex)
{

}
