The below is the entity, when I am going to add-migration, it is giving me exception.

When I am commenting out some Document & FOreignKey fields, it perfects fine but more than one foreign key it is not working fine. Here's the exception.

What is the version of EF you use? I guess that you are using a version earlier than 6.1.3
according to this issue, I think updating 'Entity Framework' will fix your problem

Hi I'm trying to implement project as mentioned in above link. I'm trying get data from ASP.NET WebAPI project and consume in Blazor project. I have no issue retrieving data from single table. But when I try to retrieve data from Secondary table . I'm getting error below:
"HttpRequestException: Response status code does not indicate success: 500 (Internal Server Error)."
I tried casting the result (in API project)explicitly to 'Employee' class before sending. Didn't work. Debug on API clearly shows returning Employee with Department information but on Blazor project while receiving getting error. Thanks in advance!!
UPDATE:
Thank you all for offering help. Here is the original code.
Models:
public class Employee
{
public int EmployeeId { get; set; }

public string FirstName { get; set; }

// If I don't include Department table. I'm able to retrieve employee table data fine in Blazor project
return await appDbContext.Employees
.Include(e => e.Department)
.FirstOrDefaultAsync(e => e.EmployeeId == employeeId);
}
}

Update :
Thanks all for response. Department is mandatory.So there is no chance of null. This is the only solution that worked. I have created another Viewmodel in Blazor project that has all fields same as Employee and Initialized Department inside ViewModelClass. Then I was able to show Employee.Department.DepartmentName in UI.
public class EmployeeViewModel
{
public int EmployeeId { get; set; }
[Required]
[MinLength(2)]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
public string Email { get; set; }
public string ConfirmEmail { get; set; }
public DateTime DateOfBrith { get; set; }
public Gender Gender { get; set; }
public int DepartmentId { get; set; }
public Department Department { get; set; }= new Department();
public string PhotoPath { get; set; }
}
Is the web API project also loading as well as the client project in the web browser?
If not you may need to go to the properties of your solution from solution Explorer to launch multiple projects.
It may be a good idea to navigate to the web API and type in the following string into the address bar after the port number:
/api/employees/1
Then if the browser displays Json then all is okay. Otherwise you can set a breakpoint in your web API and further investigate where the error is occurring.
You may want to use something like Postman to test the web API.
I'm getting this error only on release build of xamarin forms IOS.
App.xaml.cs
public partial class App : Application

public static PlayersViewModel PlayersViewModel = new PlayersViewModel();

public static MyTournamentRoundsViewModel MyTournamentRoundsViewModel = new MyTournamentRoundsViewModel();
public static MyTournamentScoresViewModel MyTournamentScoresViewModel = new MyTournamentScoresViewModel();
public static MyTournamentYardagesViewModel MyTournamentYardagesViewModel = new MyTournamentYardagesViewModel();
Whatever viewmodel is called first (that calls azure mobile services)- causes the error.
ShapesViewModel.cs
public class ShapesViewModel : BaseViewModel
{
public MobileServiceCollection<GeoPosShapes, GeoPosShapes> shapeItems;
public IMobileServiceSyncTable<AzureShapes> ShapesTable = App.MobileService.GetSyncTable<AzureShapes>(); // offline sync
The error occurs on calling

Any help would be appreciated - as this is the last step before getting app published on IOS AppStore
You have not given is all the types involved. See:
No 'id' member found on type 'RangeFinder.Models.ShapeTypes'.
You explicitly want to look at RangeFinder.Models.ShapeTypes type. There is no id field on that type.
I am trying to build one to many relationship between AspnetUsers and Trip.
My Trip class is as given below:
public class Trip
{
public int TripId { get; set; }
public string TripName { get; set; }
public string ApplicationUserId { get; set; }
public virtual ApplicationUser ApplicationUser { get; set; }
}
I have added following in IdentityModel:
public virtual ICollection<Trip> Trips {get; set; }
Now when I try to run this or update-database I get the following error:
System.InvalidOperationException: Multiple object sets per type are not supported. The object sets 'ApplicationUsers' and 'Users' can both contain instances of type 'IdentityRelationship.Models.ApplicationUser'

Multiple object sets per type are not supported. The object sets 'ApplicationUsers' and 'Users' can both contain instances of type 'IdentityRelationship.Models.ApplicationUser'.
Can anyone please tell me what's going on and how to solve this?
In my opinion class called Trip, should contains IdentityModel's foreign key virtual property (navigation property).
Fore example:
public class Trip{
public int TripId { get; set; }
public string TripName { get; set; }
public string ApplicationUserId { get; set; }
public virtual ApplicationUser ApplicationUser { get; set; }
public int IdentityModelId{ get; set; }
[ForeignKey("IdentityModelId")]
public virtual IdentityModel IdentityModel{get; set; }
}
And afther that it should be possible to populate the collection into Trips property at IdentityModel class.
The table with multiple columns pointing to same People table i.e. person class
namespace IGRS.Models

This is the auto generated by database first MVC4 methodology Entity Framework 5 VS2012 defaults:

}
And the NRIInformation table info:
namespace IGRS.Models
{
using System;
using System.Collections.Generic;
public partial class NRIInformation
{
public NRIInformation()
{
this.HinduMarriageForms = new HashSet<HinduMarriageForm>();
this.HinduMarriageForms1 = new HashSet<HinduMarriageForm>();
}
public int ID { get; set; }
public string PassportNumber { get; set; }
public string PassportIssuedBy { get; set; }
public System.DateTime PassportValidUpto { get; set; }
public string VisaIssued { get; set; }
public System.DateTime VisaValidUpto { get; set; }
public int TypeOfResidentID { get; set; }
public string SocialSecurityNumber { get; set; }
public virtual ICollection<HinduMarriageForm> HinduMarriageForms { get; set; }
public virtual ICollection<HinduMarriageForm> HinduMarriageForms1 { get; set; }
}
}
This upon running on the HinduMarriageForm controller code obvioous so not providing gives the error:

So far I have tried a bunch of things using ForeignKey and Column with Order decorations etc but can only reduce number of errors. I am not sure what is going on wrong with the reflection. Also here are the SQL create table scripts for the 2 foreign key tables and the source table:

Not pasting the foreign key SQL creation statements assume they are all there in back end sql server database.
This whole MVC 4 Entity Framework 5 project was Database First Driven and giving these errors. The simpler tables which dont have multiple columns linked to same foreign key table and column are working fine.
From this section of your error message:
Source Error:
Line 20: { Line 21: var hindumarriageforms = db.HinduMarriageForms.Include(h => h.MarriageVenue).Include(h => h.SR).Include(h => h.SRO); Line 22: return View(hindumarriageforms.ToList()); Line 23: } Line 24:
Source File: c:\Users\gilgamesh\Documents\Visual Studio 2012\Projects\IGRS\IGRS\Controllers\HinduMarriageFormController.cs Line: 22
If you also include the NRIInformation and Person tables, does the problem go away?
var hindumarriageforms = db.HinduMarriageForms.Include(h => h.MarriageVenue).Include(h => h.SR).Include(h => h.SRO).Include(h => h.Person).Include(h => h.NRIInformation);
Edit: As an aside, I usually like to rename the virtuals where instead of it being Person1, Person2, Person3... etc. Change it to PersonForHusband, PersonForHusbandsFather, PersonForHusbandsMother, etc. so that the navigation properties are clear and you don't accidentally use the wrong one. Makes programming with those classes later so much easier to use.
