xaml - Changing PivotItem with swipe gesture crashes app (Visual C#, Windows Runtime, Windows Phone) -

-

in windows phone project (visual c#, windows runtime) i've got xaml page 2 pivotitems. use pivot_selectionchanged event change bottomappbar. works fine when pivotitem changed tapping header of inactive pivotitem, when use swipe gesture change it, content of next pivotitem doesn't load , debugger breaks in

#if debug && !disable_xaml_generated_break_on_unhandled_exception     unhandledexception += (sender, e) =>     {         if (global::system.diagnostics.debugger.isattached) global::system.diagnostics.debugger.break();     }; #endif

with no details exception. double-checked both xaml , visual c# code, seems ok.

how can fix that? (disabling swipe gesture ok.)

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
