Auto generate GUID in mvc5 that uses EF

EF6.0

I have an mvc5 application that is connected to a EF database. Some fields in this database are meant to be autogenerated as declared in SQL, but when used in MVC and upon inserting records, the GUID only contains the value of 0 for all records. How can I resolve this? Any help will be appreciated. Thanks.

What I have tried:

public partial class Store
    {
        public int StoreID { get; set; }
        public int CustomerID { get; set; }
        public string StoreName { get; set; }
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public System.Guid StoreUID { get; set; }
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int StoreNumber { get; set; }
        public string StoreLogo { get; set; }
        public string StoreLogoPath { get; set; }
        public string StoreAddress { get; set; }
        public string StoreCity { get; set; }
        public string StoreRegion { get; set; }
        public string StoreCountry { get; set; }

        public virtual Customer Customer { get; set; }
    }
