How to create ASP.Net Identity tables inside existing database?
Solution 1
Will there the user tables be added to the existing sql server, or is this user database a completely separate database?
You do not need two databases - you can create Identity tables inside your existing database.
ASP.Net Identity uses Entity Framework Code First. Therefore, before running your application first time, you want to update Connection String same as existing database which is normally inside ApplicationDbContext.
If you already have two separate databases and want to merge them, you want to use tools such as RedGate - SQL Compare and Data Compare.
Merging two database is totally out of original question; please kindly create a separate question if you have one.
Solution 2
Run this SQL Script on the database.

Solution 3
With DB First, changing the connection string is not going to cause Identity 2.0 to create tables in the DB.
CORRECTION: I originally had my Identity tables in the DB under an Identity schema and when I registered new users using the below, new tables were written into my DB under the dbo schema.
You have to create a dummy project first using Code First, build and run the project, go onto the now running app in your web browser, register a user with a dummy email and password, this will cause Entity FrameWork Code First(?) to create all the Identity 2.0 DB tables in your dummy database. You'll then want to export the dummy tables to SQL script and import them into your existing DB that you want to use them in. There should be 5 tables: AspNetUserRoles, AspNetRoles, AspNetUsers, AspNetUserClaims, and AspNetUserLogins.
I have a ADO.Net Entity Model(.edmx file) for my main DB models and created another .edmx for the Identity Models(I named: IdentityDbEntities). That's when you should change the connection string from "DefaultConnection":
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("IdentityDbEntitiesString", throwIfV1Schema: false)
{
}
VERY IMPORTANT: In your Web.config file, you must add an extra connection string that you'll be using above. Looks like (I'm using a SQL Server Dev environment, so your connection strings could change):
<connectionStrings>
<add name="IdentityDbEntitiesString"
connectionString="Data Source=#MyServerAddress#;
Initial Catalog=#DbName#;
Integrated Security=SSPI;"
providerName="System.Data.SqlClient" />
<add name="IdentityDbEntities"
connectionString="metadata=res://*/Models.IdentityModel.csdl|
res://*/Models.IdentityModel.ssdl|
res://*/Models.IdentityModel.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=#MyServerAddress#;
initial catalog=#DbName#;
integrated security=True;multipleactiveresultsets=True;
application name=EntityFramework""
providerName="System.Data.EntityClient" /> </connectionStrings>
Anything inside #'s like #DbName# will be custom to you.

I did a sequence of steps:
Step 1. Create a brand-new (and temporary) project use the template what likes your existing project. When creating new project, you must choose option has Identity, and Individual...
Step 2. You already have a project. Add Scaffolding items... Choose Identity...
Step 3. Open Package Manager Console, run command
Update-Database
you will see at console like this (not exactly like yours, because I use new version of Visual Studio, .NET Core framework, posted time, etc.)

I am building my first MVC 5 / Entity Framework application. I used the database first method to pull in my data from an existing SQL server. The existing SQL database receives it's data from a separate web forms .net application.
Moving forward, the new MVC application and the existing web forms application will share the database.
I am using Identity to create user accounts within the MVC application. So at this point, I have 2 data connections in my MVC application. One for the user accounts and the other for the existing SQL server.
Is this the best way to set up the MVC project? Moving forward, will I be able to access the user database from the web forms application?
I am a newbie, and I want to make sure I am setting this up correctly.

Newclique over 2 yearsThis was really close. For me, I had to first use the command: Add-Migration Identity before I could run Update-Database. Thanks!
