这是 Startup.cs

 public class Startup
{
    public Startup(IConfiguration configuration)    
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }   

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<ApplicationDbContext>(options => options.UseMySql(Configuration.GetConnectionString("DbCihanConnection")));
        services.AddDbContext<ApplicationIdentityDbContext>(options => options.UseMySql(Configuration.GetConnectionString("DbCihanConnection")));

        services.AddIdentity<ApplicationUser, IdentityRole>(options =>   
        {  
            options.User.RequireUniqueEmail =true;                               

            options.Password.RequiredLength = 7;
            options.Password.RequireLowercase = false;
            options.Password.RequireUppercase = false;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireDigit = false;

        })
                .AddEntityFrameworkStores<ApplicationIdentityDbContext>()
                .AddDefaultTokenProviders();
        services.ConfigureApplicationCookie(options =>
        {
            options.AccessDeniedPath = "/Admin/Account/AccessDenied";
            options.Cookie.Name = "CookieCihan";
            options.LoginPath = "/Admin/Account/Login";                      

        });

        services.AddMvc()
            .SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
    }
    public void Configure(IApplicationBuilder app, IHostingEnvironment env, UserManager<ApplicationUser> userManager,RoleManager<IdentityRole> roleManager)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseForwardedHeaders(new ForwardedHeadersOptions
        {
            ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
        });
        app.UseStatusCodePagesWithReExecute("/Errors/Index", "?statusCode={0}");   
        app.UseStaticFiles();               
        app.UseAuthentication();   
        app.UseHttpsRedirection();

        app.UseMvc(routes =>
        {
            routes.MapRoute(name: "areas",
                template: "{area:exists}/{controller=Admin}/{action=Index}/{id?}");
        });

        app.UseMvc(routes =>        
        {
            routes.MapRoute(name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

        MyIdentityDataInitializer.SeedData(userManager, roleManager,app);

    }
}

这是 Program.cs

 public class Program
{
    public static void Main(string[] args)
    {
        CreateWebHostBuilder(args).Build().Run();
    }


        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)            
                .UseStartup<Startup>()
                .UseDefaultServiceProvider(options=>options.ValidateScopes=false);
    }

您正在尝试将 UserManager 注入尚未注册到服务中的配置方法。

因此，您的应用程序无法解析 UserManager
