Hello 

I have just upgraded my test project and I had got this error (when I was trying login) . Microsoft.AspNetCore.All 2.1.0 - Microsoft.VisualStudio.Web.CodeGeneration.Design - 2.1.0

If I downgrade (demote) my project , there is no problem  Microsoft.AspNetCore.All 2.0.8

An unhandled exception occurred while processing the request.

<div class="titleerror">InvalidOperationException: Cannot create a DbSet for 'ApplicationUser' because this type is not included in the model for the context.</div>

Microsoft.EntityFrameworkCore.Internal.InternalDbSet<TEntity>.get_EntityType()

....................

MIS.WebUI.Controllers.SecurityController.Login(LoginViewModel loginViewModel, string returnUrl) in SecurityController.cs

<div class="source">

120. ApplicationUser user = await UserManager.FindByEmailAsync(loginViewModel.Username);

</div>
