I just replicated the problem with a fresh template download just now.

Steps:

Download .Net Core 1.1 MVC template from ABP site.
Open solution and add connection string
Set Migrator project as startup project
Run solution, allow migrator to create host and tenant DB
Run app, all normal, ABP default site opens and works normally
Add custom entity into MyProject.Core project
Add custom entity DBSet entry into context file in MyProject.EntityFrameworkCore project
Run the application - You get error, app does not load.
Try to add migration for the custom entities - You get error, migration NOT created.
Remove all references to custom entities from context file in MyProject.EntityFrameworkCore project
Run app - You get error, app does not load

Here is the complete error message.

System.InvalidOperationException: Unable to determine the relationship represented by navigation property 'User.DeleterUser' of type 'User'. Either manually configure the relationship, or ignore this property from the model.

I did one more test.

I removed all my custom entities from the dbContext file.
I add one simple entity with just 3 properties and then added that to dbContext file.
Ran add-migration cmd via pkg manager console and still the same error is reported. Basically the minute I introduce any type of custom entity in the solution the error comes up, during add migration or in the browser when you run the app.

Thanks.

@ismcagdas - Thank you very much!

One other issue I am having on this same template is with the localization function "L". I copied the tenant index view and just updated the fields for my custom entity. On my new copied page I keep getting error "L does not exist in this context" I have all the same using statements and my controller inherits from the same base controller. My page, controller and views are all located in the Areas/App/ folder structure.

I tried again with my template this morning and no matter what kind of custom entity I add into the solution I keep getting the same error.

I took the error text from the log file this time and it seems to be pointing to the tenant view model?

MyCo.MyApp.Web.Views.Shared.Components.TenantChange.TenantChangeViewModel

Try to add migration for the custom entities - You get error, migration NOT created.

Remove all references to custom entities from context file in MyProject.EntityFrameworkCore project

Run app - You get error, app does not load

At step 8, application should work without update-database (if there is no any db operation about custom entity).
Before step-8, are you getting any compile time errors?
And one last thing, could you share your customentity that you added?

I just repeated all my steps from 1 again. This time I added one very simple entity that has no FKs. I tried to scaffold the migration for this table and ran into the error.

Here is my simple entity:

public partial class InvCtry
    {
        public InvCtry()
        {
        }

        public string CtryIsoAlphaCd { get; set; }
        public string CtryNm { get; set; }
        public string CtrySrceCd { get; set; }
        public string EnblIn { get; set; }

    }

Hi,

I tried to download your solution from Drive but it lasts very long time for Google Drive to zip and serve the file. So what i want from you is; zip the solution folder and send the link to <a href="mailto:[email protected]">[email protected]</a>

Hi,

I found the problem in your solution. You have commented out base OnModelCreating, that's why migrations cannot be done correctly.

//base.OnModelCreating(modelBuilder);

Using the empty DbContext below will solve your problem ;) .

public class RemodelOpsDbContext : AbpZeroDbContext<Tenant, Role, User, RemodelOpsDbContext>
    { 
        public RemodelOpsDbContext(DbContextOptions<RemodelOpsDbContext> options)
            : base(options)
        {

        }
    }
