BadBadBadGetter.cs

        public int SomeCountValue
        {
            get
            {
                if (_someCountValue == -1)
                {
                    using (IUnitOfWork unitOfWork = new UnitOfWork())
                    {
                        _someCountValue = unitOfWork.GetQueryObjectInstance<ISomeQuery>()
                            .Where(Property1, Property2, Property3, Property4 ?? 0).Select();
                    }
                }

                return _someCountValue ;
            }
        }

A property getter should never do work. It ESPECIALLY should not make a call to the database. We have methods to do work. Code calling a property getter should be able to assume that the call takes a negligible amount of time - this is clearly not the case in this getter.
