多租户解析管理站点中的租户上下文

Question

I'm developing a multi-tenant application in dot net core 2.1. I have used the identity framework for user management. I have two web projects and two data context for tenant and system.

SystemDb (SystemDbContext)- central database

TenantDb (TenantDbContext)- tenant (this has TenantId filter)

When I create a tenant from system portal, I want to create a default admin user in tenant database. I want to know what is the best way to resolve the tenant data context. Tenant Entity has the connection to the database.

public class TenantManagementService: ITenantManagementService
{
    private readonly ISystemDbContext _systemDbContext;
    private readonly UserManager<SystemUser> _userManager;

    public InsertTenantDetailsCommandHandler(ISystemDbContext systemDbContext, UserManager<SystemUser> userManager)
    {
        _systemDbContext = systemDbContext;
    }

    public async Task CreateTenant(Tenant tenant)
    {
        await _systemDbContext.Tenants.AddAsync(tenant);
        await _systemDbContext.SaveChangesAsync();

        // I need to create default user in tenantDbContext
    }
}

您可以将租户上下文本身放置在其他项目中，并在System项目中引用生成的dll文件。
