c# - Adding int property, EF keeps making it nullable column? -

-

i'm adding int property called order existing entity has records in db tables. 

public class page : content {     // ...     public int order { get; set; }     // ...  }

however, when run "update-database", it's adding column nullable default value of null. tried using [defaultvalue(0)], setting default in constructor. neither work.

how can add column/property existing set of data , have populate non-null value of 0? thanks.

that's because of inheritance. not properties in derived types can defined not-nullable, because types in upper level of hierarchy doesn't have properties.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
