.net-4.0

问题 As in the following link, one can stop, start, and "stop, then start" a service using C# code. http://www.csharp-examples.net/restart-windows-service/ I have baked a .NET service that does implement OnStart and OnStop . However, I need to implement a "smart restart" functionality which is more involved than just stopping and then starting. I need to keep the downtime to just a few seconds if that (but Stop + Start can take minutes in this case when done cleanly, and I must do it cleanly), and

问题 Background: I'm new to WinDbg and trying to get it running for the first time. I want to examine a memory dump I took from a running ASP.NET 4 site hosted in IIS 7 on Windows Server 2008 (x86) and downloaded to my local machine. I installed the debugging tools and launched WinDbg for the first time, opening the crash dump. I went to File | Symbol File Path and set the path to *srv*c:\symbols*http://msdl.microsoft.com/download/symbols* and waited for all the symbols to load. When trying to

问题 I'm just looking in to the new .NET 4.0 features. With that, I'm attempting a simple calculation using Parallel.For and a normal for(x;x;x) loop. However, I'm getting different results about 50% of the time. long sum = 0; Parallel.For(1, 10000, y => { sum += y; } ); Console.WriteLine(sum.ToString()); sum = 0; for (int y = 1; y < 10000; y++) { sum += y; } Console.WriteLine(sum.ToString()); My guess is that the threads are trying to update "sum" at the same time. Is there an obvious way around

问题 I've noticed that if I build my WPF application for Any CPU/x64, it takes MUCH longer to start (on the order of about 20 seconds) or to load new controls than it does if started on x86 (in release & debug modes, inside or outside of VS). This occurs with even the simplest WPF apps. The problem is discussed in this MSDN thread, but no answer was provided there. This happens only with .NET 4.0 -- in 3.5 SP1, x64 was just as fast as x86. Interestingly, Microsoft seems to know about this problem

问题 I've been tasked in creating a new module for an application, and so, I'm adding new DLLs to the project. This is all fine and well. However, in my DLLs I'd like to use a new version of an external DLL (over which I have no control). If I just reference the new DLL and work with that one only, my code will work, but the old code will stop functioning. Could not load file or assembly 'itextsharp, Version=5.0.6.0, Culture=neutral, PublicKeyToken=8354ae6d2174ddca' or one of its dependencies. The

问题 I'm using the TPL (Task Parallel Library) in .NET 4.0. I want to centralize the handling logic of all unhandled exceptions by using the Thread.GetDomain().UnhandledException event. However, in my application, the event is never fired for threads started with TPL code, e.g. Task.Factory.StartNew(...) . The event is indeed fired if I use something like new Thread(threadStart).Start() . This MSDN article suggests to use Task.Wait() to catch the AggregateException when working with TPL, but that
