Restart application required to update information

I have a windows forms application in the mvc pattern, where I have a controller call to retrieve the information I need, which in this case is if the application movement was terminated.

The controller call is normally done like this:

_listMoviment = new MovimentController().GetRelationMoviment(UserLogged.companyCode);

which calls this method on the controller:

    public List<Moviment> GetRelationMoviment(short companyCode)
    {
        return RepositorioBase.GetRelationMoviment(companyCode);
    }

which by the way calls this method in the repository:

    public List<Moviment> GetRelationMoviment(short companyCode)
    {
        return EntityRepository.Include(x => x.Operator)
                                  .Where(x => x.CompanyCode == companyCode &&
                                              x.CompanyCodeMoviment == null)
                                  .ToList();

    }

and this flow is working normally, but it only updates the information if I restart the application, is there any way to force this update without having to restart?
