  How to get navigation properties from userManager?

  Sep 01, 2017 08:54 AM|bluMarmalade|LINK

  In my Asp.net Core 2.0 app I have an ApplicationUser class where I store names and info. But I also have set a navigation property which is a class called "Company" there.

  I use this in my controller to get the current user:

  var person = await _userManager.GetUserAsync(User);

  The problem is that the navigation property is not included in this(the other properties are however. person.Company is null). Is there a way to include it using userManager or do I have to call the ApplicationUser table again after this?

  Hi bluMarmalade,

  According to your description and code, I think you use lazy loading, if you use lazy loading, please check the following rules:

  Rules for lazy loading:

  1. context.Configuration.ProxyCreationEnabled should be true.
  2. context.Configuration.LazyLoadingEnabled should be true.
  3. Navigation property should be defined as public, virtual. Context will NOT do lazy loading if the property is not defined as virtual.

  For more details, please check this tutorial link:

  I suggest you could use Include() method of eager loading, please check: Eager Loading:
