Nuget package:

About Version

  • 6.0.x is compatible with .Net 6.0.x;
  • 5.0.x is compatible with .Net 5.0.x;
  • 3.1.x is compatible with .Net Core 3.1.x;
  • 3.0.x is compatible with .Net Core 3.0.x;


1. Create a Asp.Net Core Mvc Project with identity support

dotnet new mvc --auth Individual

2. Add reference to NHibernate.AspNetCore.Identity and NHibernate.NetCore

dotnet add package NHibernate.AspNetCore.Identity
dotnet add package NHibernate.NetCore

NHibernate will be installed automatically.

3. Setup database

  • Use the sql scripts in database folder to create aspnet identity related tables, only support postgresql, mssql and mysql now;

    If you want other database support, please let me know, any issue, pull request is welcome!

  • Config NHibernate to use your database;

4. Change Startup.cs to use database and nhibernate

public class Startup {

    public void ConfigureServices(
        IServiceCollection services
    ) {
        // Remove EFCore stores.
        // services.AddDbContext<ApplicationDbContext>(
        // options =>
        //     options.UseSqlite(Configuration.GetConnectionString("DefaultConnection")));
        // services.AddDefaultIdentity<IdentityUser>()
        //     .AddEntityFrameworkStores<ApplicationDbContext>();

        // Add Hibernate stores
        var cfg = new Configuration();
        var file = Path.Combine(
        // Add identity mapping based on dialect config (dialet must contains
        // PostgreSQL, MySQL, MsSql or Sqlite)
        // using default xml mapping.
        // using `NHibernate.Mapping.ByCode`, please comment the line above,
        // and uncomment line flowing lines;
        // var modelMapper = new NHibernate.Mapping.ByCode.ModelMapper();
        // modelMapper.AddMapping<WebTest.Entities.AppRoleMapping>();
        // modelMapper.AddMapping<WebTest.Entities.AppUserMapping>();
        // modelMapper.AddMapping<WebTest.Entities.TodoItemMapping>();
        // var mappings = modelMapper.CompileMappingForAllExplicitlyAddedEntities();
        // cfg.AddMapping(mappings);



Note: When using with SqlServer, you need add System.Data.SqlClient package to your project.

For more detailed samples, please look at the WebTest project.
