Removing an entity error: System.ObjectDisposedException: Cannot access a disposed object. Object name: 'DriverAppUnitOfWork'.

Lightspeed version: 5.0.2302.0

UPDATE: It does seem like something is up with the DriverAppUnitOfWork, I created a new entity just for the purposes of deleting it and I still go the exception. More details on the DriverAppUnitOfWork below

Although the error seems like there is something wrong with the DriverAppUnitOfWork, it's actually ok - the problem is with the entity.

I have a "person" entity that I get in a UnitOfWork like this:

using (var uow = Code.Get.Uow) {
    Device d = uow.Devices.FirstOrDefault(x=>x.Token == "xxx"); 
    // we have a person from the device
    person = d.Person;
}

Where Code.Get.Uow basically just gets a context and returns context.CreateUnitOfWork()

Then later in the code I have another UnitOfWork where I attach the person and try and delete them:

using (var uow = Code.Get.Uow) {
    uow.Attach(person);
    if (deletePerson) { 
        uow.Remove(person); // this is blowing up
    }
}

I have tried adding a uow.Detach(person) in the first uow but that doesn't do anything.

I've checked the uow IdentityMap and the person object is definitely in there, so I don't understand why it's saying it is disposed.

Is it because I got it off a device entity in the first place?

If I check the person entity when the exception is thrown I can see that it has been marked as Deleted.

Some more info on how I'm getting a UoW, it's worked fine for me so far for reading and updating data. It doesn't like this Remove though. Is it something to do with using this same static method more than once?

I'm using Web API (so no per request scope available) and here is the code I'm using to create the uow:

public static DriverAppUnitOfWork Uow {
    get {
        var context = new LightSpeedContext<DriverAppUnitOfWork>("default");
        context.ConnectionString = Util.GetConnectionString();
        return context.CreateUnitOfWork();
    }
}
