Cannot Create A DbSet for ApplicationUser - entity-framework

Question

I have an asp.net core project that I am refactoring. Previously I had all my database logic contained within the project, however as we are now adding a WebAPI, I have moved the database logic to a separate .net core standard project, so it is shared between the two projects.
This seems to work fine in the new web api, however I am having issues in the original project, relating to signInManager and the ApplicationUser class.
All compiles just fine, however, I get the following error during runtime:
InvalidOperationException: Cannot create a DbSet for 'ApplicationUser' because this type is not included in the model for the context.`
I have also moved this ApplicationUser class to the new DAL project, and as far as I can see, i've updated all references to it (certainly enough to pass the compile time checks).
My startup.cs is as follows:
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
// password policy settings
services.Configure<IdentityOptions>(options =>
{
// Password settings
options.Password.RequireDigit = true;
options.Password.RequiredLength = 8;
options.Password.RequireNonAlphanumeric = false;
options.Password.RequireUppercase = true;
options.Password.RequireLowercase = false;
options.Password.RequiredUniqueChars = 6;
// Lockout settings
options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
options.Lockout.MaxFailedAccessAttempts = 10;
options.Lockout.AllowedForNewUsers = true;
// User settings
options.User.RequireUniqueEmail = true;
});
// Add session cookie
services.ConfigureApplicationCookie(options =>
{
// Cookie settings
options.Cookie.HttpOnly = true;
options.ExpireTimeSpan = TimeSpan.FromMinutes(30);
// If the LoginPath isn't set, ASP.NET Core defaults
// the path to /Account/Login.
options.LoginPath = "/Account/Login";
// If the AccessDeniedPath isn't set, ASP.NET Core defaults
// the path to /Account/AccessDenied.
options.AccessDeniedPath = "/Account/AccessDenied";
options.SlidingExpiration = true;
// Disable redirect to login page for unauthorized requests to / api resources
options.Events.OnRedirectToLogin = context =>
{
if (context.Request.Path.StartsWithSegments("/api") && context.Response.StatusCode == StatusCodes.Status200OK)
{
context.Response.StatusCode = StatusCodes.Status401Unauthorized;
return Task.FromResult<object>(null);
}
else
{
context.Response.Redirect(context.RedirectUri);
return Task.FromResult<object>(null);
}
};
});
// Add application services.
services.AddTransient<IEmailSender, EmailSender>();
// add our Db handlers
services.AddScoped<DAL.Services.Interfaces.IServices, DAL.Services.Services>();
services.AddMvc();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, IServiceProvider services)
{
if (env.IsDevelopment())
{
app.UseBrowserLink();
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
var cultureInfo = new CultureInfo("en-GB");
CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;
app.UseStaticFiles();
app.UseAuthentication();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
}
I have a "using" statement at the top as follows:
using IceBowl.DAL;
using IceBowl.DAL.Models;
So the call to "AddIdentity" is passing in the right ApplicationUser - in fact, there is only one ApplicationUser class, I deleted the original.
The code seems to be having issues on the following line:
var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);
There's something it doesnt like about sign in manager, but I'm at a loss to explain what. All references have been updated and now point to the DAL that contains the datacontext and ApplicationUser class.
Any pointers?
