The Abp package.
If you don't want the user management system (Module Zero), you'll need to implement IPermissionChecker and replace IAuthorizationHelper.
See this SO answer on Checking ABP permissions from claims.

Yes. You can define an interface, e.g. IHasConcurrency as suggested in aspnetboilerplate/aspnetboilerplate#50.

A simple way to handle that in your DbContext with ABP v2.3.0+, adapted from EF6 answer in #4146:
protected override void ApplyAbpConceptsForModifiedEntity(EntityEntry entry, long? userId, EntityChangeReport changeReport)
{
if (entry.Entity is MyRowVersionEntity)
{
entry.OriginalValues["RowVersion"] = entry.CurrentValues["RowVersion"];
}
base.ApplyAbpConceptsForModifiedEntity(entry, userId, changeReport);
}
Your question title and code says EF Core.
User.IsActive being false means the admin disabled the account.
It is inappropriate for a user action to enable one's own account.
You should filter EntityChange by ec.EntityId == entity.Id, and include its ec.PropertyChanges collection.
var entityChanges = _entityChangeRepository
.GetAllIncluding(ec => ec.PropertyChanges)
.Where(ec => ec.EntityId == entity.Id)
.ToList();
P.S. I did see your message before, but didn't understand how it related to the original question. Please create a new question in future.
