Run code below Actual Results: 5000 iterations, 77 exceptions Expected Results: 5000 iterations, 0 exceptions How often does this happen? Always. Code to reproduce: public static class AppMainEntry { class TestEntity { public int contents { get; set; } } [STAThread] public static void Main() { int i = 0, exceptions = 0; for (; i < 5000; i++) { using (var db = new Entity(new Npgsql.NpgsqlConnection( "host=localhost;DATABASE=test;USER=test;PASSWORD=xxxxx;SSLMODE=Prefer;SSL=True"), new DbLinq.PostgreSql.PgsqlVendor())) try { db.ExecuteQuery<TestEntity>("SELECT 1 as contents").ToList(); } catch (Exception ex) { exceptions++; } } Console.WriteLine(i.ToString() + " iterations, " + exceptions.ToString() + " exceptions"); } Additional information: Exceptions occur in DynamicInvoke(): System.InvalidCastException: Cannot cast from source type to destination type. at System.Delegate.get_Method () [0x00000] at System.Delegate.DynamicInvokeImpl (System.Object[] args) [0x00000] at System.MulticastDelegate.DynamicInvokeImpl (System.Object[] args) [0x00000] at System.Delegate.DynamicInvoke (System.Object[] args) [0x00000] at DbLinq.Data.Linq.Sugar.Implementation.QueryRunner+<EnumerateResult>d__b.MoveNext () [0x00000] at DbLinq.Data.Linq.Sugar.Implementation.QueryRunner+<ExecuteSelect>d__0.MoveNext () [0x00000] at DbLinq.Data.Linq.DataContext+<CreateExecuteQueryEnumerable>d__d`1[MyApp.UI.AppMainEntry+TestEntity].MoveNext () [0x00000] at System.Collections.Generic.List`1[Myapp.UI.AppMainEntry+TestEntity].AddEnumerable (IEnumerable`1 enumerable) [0x00000] at System.Collections.Generic.List`1[Myapp.UI.AppMainEntry+TestEntity]..ctor (IEnumerable`1 collection) [0x00000] at System.Linq.Enumerable.ToList[TestEntity] (IEnumerable`1 source) [0x00000] at Myapp.UI.AppMainEntry.Main () [0x00000] monot...@mono:~/www/htdocs/demo/bin$ mono --version Mono JIT compiler version 2.5 (/trunk/mono r135592 Sat Jun 6 15:56:42 EEST 2009) Copyright (C) 2002-2008 Novell, Inc and Contributors. www.mono-project.com TLS: __thread GC: Included Boehm (with typed GC and Parallel Mark) SIGSEGV: altstack Notifications: epoll Architecture: amd64 Disabled: none monot...@mono:~/www/htdocs/demo/bin$ uname -a Linux mono.test.xxxxx.com 2.6.18.8-xenU #3 SMP Fri Apr 24 13:30:30 EEST 2009 x86_64 GNU/Linux -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
