https://bugzilla.novell.com/show_bug.cgi?id=664639#c0 Summary: Spawning a new thread using BackgroundWorker, the new thread will be blocked until original thread ends Classification: Mono Product: Mono: Runtime Version: 2.8.x Platform: x86 OS/Version: Windows 7 Status: NEW Severity: Normal Priority: P5 - None Component: misc AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: Customer Blocker: No Description of Problem: The situation is like this: 1) main thread, Thread-A spawns a WorkerBackground thread Thread-B. Work running under the WokerBackground (Thread-B) spawns a new thread Thread-C. This new, Thread-C is blocked until Thread-B ends. Steps to reproduce the problem: using System; using System.ComponentModel; namespace TestBackgroundWorker { class MainClass { public static void Main (string[] args) { BackgroundWorker thread_B = new BackgroundWorker(); thread_B.DoWork += HandleWorkerDoWork; thread_B.RunWorkerAsync(); System.Threading.Thread.Sleep(new TimeSpan(0,0,5)); Console.WriteLine ("End of Main Thread(Thread_A)"); } static void HandleWorkerDoWork (object sender, DoWorkEventArgs e) { BackgroundWorker thread_C = new BackgroundWorker(); thread_C.DoWork += HandleWorkerDoWork1; thread_C.RunWorkerAsync(); System.Threading.Thread.Sleep(new TimeSpan(0,0,3)); Console.WriteLine("end of Thread B"); } static void HandleWorkerDoWork1 (object sender, DoWorkEventArgs e) { Console.WriteLine("Begin of Thread C"); } } } Actual Results using Mono 2.8.1 runtime: end of Thread B Begin of Thread C End of Main Thread(Thread_A) Press any key to continue . . . Expected Results Microsoft .NET runtime: Begin of Thread C end of Thread B End of Main Thread(Thread_A) Press any key to continue How often does this happen?
