问题 i have 2 assemblies. i added classlib1 into classLib2 references. like that: and i used it like that: namespace ClassLibrary2 { public class Class1 { public Class1() { } public int GetSum(int a , int b) { try { ClassLibrary1.Class1 ctx = new ClassLibrary1.Class1(); return ctx.Sum(a, b); } catch { return -1; } } } } Also i want to load (class1lib and Class2Lib) another C# project dynamically by using AppDomain. using System; using System.Collections.Generic; using System.Linq; using System.Web

Passing an unmanaged pointer between two AppDomains (By indirect call)

只愿长相守 提交于 2019-12-08 05:59:28
问题 .NET 4.5, 64bit Win8 I have two MSMQ running under WCF and hosted under Windows Activation Service. Execute MSMQ: Responsible for calling an unmanaged function and obtaining a pointer IntPtr to 4GB array in addition to other limited size variables. This array is not that important and shouldn't be blocking the queue until it is passed to the DB and having this queue free is a priority. Passing the pointer to the Save MSMQ (Hypothesis). Save MSMQ: Should save the array to the DB across the

Unload event for the default AppDomain?

假装没事ソ 提交于 2019-12-08 05:26:26
I need to have an event fired whenever any AppDomain unloads - including the default one of the process. The problem with AppDomain.DomainUnload is that it only fires for non-default AppDomains. Furthermore, AppDomain.ProcessExit has limited execution time, which I cannot rely on. Any suggestions as to how I can achieve this would be greatly appreciated! (Alternatively, having an event fired when a background thread (Thread.IsBackground == True) works too.) jgauffin Why do you not put your code in the end of Main? As for an event: No there is no event which will get executed when the

.Net CLR Unloading vs shutdown?

孤人 提交于 2019-12-08 02:49:19
问题 What Causes Finalize Methods to Be Called ? 2 answers( of 4 ) to this question are : The CLR is unloading an AppDomain When an AppDomain unloads, the CLR considers nothing in the AppDomain to be a root, and a garbage collection consisting of all generations is performed. The CLR is shutting down The CLR shuts down when a process terminates normally (as opposed to an external shutdown via Task Manager, for example). I assume that The CLR is unloading an AppDomain is when the program (console

Why does AppDomain.Unload() error in finalizer?

三世轮回 提交于 2019-12-07 21:24:32
问题 Here's some sample code: using System; namespace UnloadFromFinalizer { class Program { static void Main(string[] args) { Program p = new Program(); } AppDomain domain; Program() { this.domain = AppDomain.CreateDomain("MyDomain"); } ~Program() { AppDomain.Unload(this.domain);//<-- Exception thrown here } } } I have a class that creates an AppDomain in the constructor to be used over the lifetime of the object. I'd like to properly cleanup the AppDomain, so I thought I would call Unload in the

Plugin AppDomains Workaround

非 Y 不嫁゛ 提交于 2019-12-07 17:12:21
问题 When dealing with plugin assemblies in their own subdirectories, there is the well-known problem that these assemblies fail to load once they try to load their respective dependencies from their subdirectories. A solution is to load the plugins in AppDomains which had their PrivateBinPath set in their AppDomainSetup object upon initialization. However, this causes other difficulties concerning marshalling/cross-AppDomain communication, in particular if the plugins are supposed to provide some

Loading services from other .dll and run them isolated

纵饮孤独 提交于 2019-12-07 13:38:24
问题 I'd like to run several services from different .dll's in a isolated way. Basically, all services are derived from RoleEntryPoint , and I want to load each one in a separated AppDomain and run it there in a different thread. So far, I can locate the service and get its type: String pathToDll = @"C:\....\bin\Debug\ChildWorkerRole.dll"; Assembly assembly = Assembly.LoadFrom(pathToDll); Type serviceType = assembly.GetTypes().SingleOrDefault(t => t.BaseType == typeof(RoleEntryPoint)); And also

CreateInstance of a Type in another AppDomain

倖福魔咒の 提交于 2019-12-07 13:00:54
问题 My scenario is that I have a .net application (let's say a Console App) that creates AppDomains. It then needs to create instances and call methods on Types that are in that AppDomain. Each AppDomain has a specific directory where are it's dependecies should be, which is not under (or even near) the Console Apps directory. Here's my simple code: string baseDirectory = "c:\foo"; // <- where AppDomain's dependecies // set up the app domain AppDomainSetup setup = new AppDomainSetup(); setup

what happens when an object derives from MarshalByRefObject and is also marked [Serializable]?

安稳与你 提交于 2019-12-07 12:55:36
问题 I'm working on my first project that uses AppDomains and I'm wondering what happens when an object derives from MarshalByRefObject and is also marked [Serializable]? for example: [Serializable] public class DummyClass: MarshalByRefObject { } 回答1: It gets marshalled by reference, but can still be serialised for other use-cases for serialisation. There's an implementation detail to this that is interesting enough to be worth noting: The formatter that is serialising for remoting uses a
