将用户ASP.NET网页表迁移到MVC 6

Question

Info
I want to 'upgrade' my ASP.NET Web Page project to an ASP.NET MVC project by just starting over, it are only a few pages and it would be good for learning.

The Issue
The current project holds a few users for authentication ASP.NET made a few tables in my database:

• Roles
• Profiles
• Users
• ...

But when I use the MVC Project I see it makes different tables for authentication:

• AspNetUserLogins
• AspNetUserRoles
• AspNetUser
• ...

The Question
How do I migrate my users or how do I tell ASP.net to use the old tables?

Answer 1

Greetings you may want to start with Database first Approach in MVC-Core but its little bit different from what you have seen so far, let me explain the steps for adding your database:

• Install Entity Framework:

Run Install-Package Microsoft.EntityFrameworkCore.SqlServer

To enable reverse engineering from an existing database we need to install a couple of other packages too.

1. Run Install-Package Microsoft.EntityFrameworkCore.Tools –Pre
2. Run Install-Package Microsoft.EntityFrameworkCore.Design
3. Run Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

Now Reverse engineer your model:

• Run the following command to create a model from the existing database. If you receive an error stating the term 'Scaffold-DbContext' is not recognized as the name of a cmdlet, then close and reopen Visual Studio.

Scaffold-DbContext "Server=(localdb)\\mssqllocaldb;Database=DataBaseName;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

The reverse engineer process created entity classes and a derived context based on the schema of the existing database. The entity classes are simple C# objects that represent the data you will be querying and saving. And now you can create a DbContext class and start using your database, so far you issue about database is over, and now i suggest you read about Identity In Asp.NET Core .
