IdentityServer4 + EF Core

1. Install thease packages

2. Using migration by package manager console, and you will see 'Data\Migrations\IdentityServer' folder

Add-Migration InitConfiguration  -Context ConfigurationDbContext -o Data\Migrations\IdentityServer\ConfiguragtionDb

Add-Migration InitConfiguration -Context PersistedGrantDbContext -o Data\Migrations\IdentityServer\PersistedGrantDb

3. Add extension method to initialize local data from config file, then use it in Configure(startup.cs)

    public static class DatabaseConfigExtensions
    {
        /// <summary>
        /// initialize identityserver local config to database
        /// </summary>
        /// <param name="app"></param>
        public static void UseDatabaseInitialize(this IApplicationBuilder app)
        {
            using (var serviceScope = app.ApplicationServices.GetService<IServiceScopeFactory>().CreateScope())
            {
                serviceScope.ServiceProvider.GetRequiredService<PersistedGrantDbContext>().Database.Migrate();

                var context = serviceScope.ServiceProvider.GetRequiredService<ConfigurationDbContext>();
                context.Database.Migrate();
                if (!context.Clients.Any())
                {
                    foreach (var client in IdentityServerConfig.GetClients())
                    {
                        context.Clients.Add(client.ToEntity());
                    }
                    
                    context.SaveChanges();
                }

                if (!context.IdentityResources.Any())
                {
                    foreach (var resource in IdentityServerConfig.GetIdentityResources())
                    {
                        context.IdentityResources.Add(resource.ToEntity());
                    }
                    context.SaveChanges();
                }

                if (!context.ApiScopes.Any())
                {
                    foreach (var resource in IdentityServerConfig.GetApiScopes())
                    {
                        context.ApiScopes.Add(resource.ToEntity());
                    }
                    context.SaveChanges();
                }
            }

        }


    }

3. Run current project, some tables had exist and local data also initialzed
