I have already deployed ASP.NET MVC web application with DB in Azure. I use EF Code First.
Now I need to add column to table Users without losing any existing data. Should I use migrations or SQL Server Management Studio or something else? And how should I use it?
I had to do the following:
enable-migrations
add property into the entity I wanted to change
add-migration
deploy

I have installed mongoDB on another machine(server) and created database there, but i want to access and use that database from another machine(my laptop) creating ASP.Net Core web api project. In ASP.Net Core, to connect the database i have to add database configuration on appssetting.json file like this
but my ConnectionString: mongodb://localhost:27017 is empty, because i am not creating database on my machine. How can i get my address/string of my database that is on another server, so that i can use it that database and make an API?
Am building an MVC5 application with Code first approach. The problem i have is that if i run the main migrations for the application models(not for identity models), then the Identity tables cannot be created when the database is already existing and has a __migrationhistory table. If i try to run a query on any of the identity tables, it will return an error that the table doesn't exist. I have searched around but all i could see are the ones talking of adding asp.net identity to an existing database first design.
If i run the identity migrations first before every other thing, it goes well but the main application entity migration will not be effected once the database has been created by the Identity framework, resulting in 'table does not exist' when i try to run any query.
How do i run either the Identity framework migration first and then run the normal entity framwork migration or vice versa. If either can be triggered automatically after the other has completed, it will be fine.
Please any suggestion will be appreciated.
I am building a Web Api which is hosted on Azure. This project has Individual User Account authentication in it.
I have accidentally deleted the AspNetUsers table from my project and I do not know if it is possible to get it back. I have also deleted the _MigrationHistory table so I cannot get it back from there.
Is there any way to retrieve this table or even create a new one with identical columns. It does not matter about the missing User data I just need to be able to Register Users again.
I am using Entity Framework Code First. I tried adding a migration and updating the database but this does not work.
I think creating a new project is a last resort fix but I really don't want to have to do that!
I am starting to look at the entity framework and especially identity. I am making an API to be used by an ASP.NET website. The problem I am having is I am used to the aspnet_regsql exe that is used by ASP.NET membership. I need to setup my application database so it has the correct tables and procedures for identity but I just cannot find out how too. I can then use the tables to link to my application tables.
So in short how can i setup the identity framework on a SQL server database?
Thanks in advance.
Check out this project: ASP.NET Identity Database (project template), it can help to create and customize ASP.NET Identity Database manually with SSDT.

As Mark Mentioned , using MigrateDatabaseToLatestVersion Initializer we can Update Our Database . and it worked for me.
