ASP.NET Identity to ASP.NET Core Identity Migration

Overview

Migrates ASP.NET MVC Identity to ASP.NET Core Identity: DbContext conversion, service registration, namespace updates, API changes, and OWIN cleanup.

Prerequisite

Verify the project uses ASP.NET Identity (e.g., references Microsoft.AspNet.Identity or IdentityDbContext). If not, skip and inform the user there is nothing to do.

Workflow

Migration Progress:
- [ ] Step 1: Install required packages
- [ ] Step 2: Update IdentityDbContext
- [ ] Step 3: Register DbContext and Identity in Program.cs
- [ ] Step 4: Add Identity middleware
- [ ] Step 5: Update Identity API usage
- [ ] Step 6: Update AccountController
- [ ] Step 7: Clean up OWIN identity code

Step 1: Install Required Packages

Ensure these NuGet packages are installed in the project (version major should match project's target framework):

• Microsoft.AspNetCore.Identity.EntityFrameworkCore
• Microsoft.EntityFrameworkCore.SqlServer
• Microsoft.AspNetCore.Identity.UI
• (latest version)
