Destruction of Native Objects with Static Storage Duration

由 给你一囗甜甜゛ 提交于 2019-11-30 13:39:53
问题 2012-12-09 Summary: In a normal mixed-mode application global native C++ destructors run as finalizers. It's not possible to change that behavior or the associated timeout. A mixed-mode assembly DLL runs C++ constructors/destructors during DLL load/unload - exactly as a native DLL. Hosting the CLR in a native executable using the COM interface allows both the deconstructors to behave as in a native DLL (the behavior I desire) and setting the timeout for finalizers (an added bonus). As far as

CLR Sync Block Address

问题 When I do: public class Employee { public int exp; } class Program { static void Main(string[] args) { Employee o1 = new Employee(); o1.exp = 3; lock (o1) { //I am here } } } and get memory of o1 (address is 0x022cf940): I realized couple of things mentioned below: Green rectangle is sync block, which is 12 Blue rectangle is 4 byte address of type Red rectangle is 4 byte integer, which is 3; Question: Where is the space of sync blocks and how can I find it? What does "12" stand for? 回答1: The

Cannot debug application in release mode even with DebugType=full

由 醉酒当歌 提交于 2019-11-30 13:02:49
We are building a solution for Release, but when attempting to attach using studio 2010 professional, no thread is showing any stack information, nor any breakpoint can be set, etc. The goal is to be able to attach the Visual Studio/JIT Debugger to the running process while having as many optimization benefits as possible. Most of our searches comes down to 'compile with debug:full' and you will be able to debug, but that doesn't seem to be the case, I thing that the JIT optimizes the code in runtime and thus we cannot debug, is this true? Is it possible to compile and tell the JIT to downplay

.NET 4.0 application on network share causes SecurityException

由 寵の児 提交于 2019-11-30 12:52:22
Today I experienced a weird problem while trying to remotely debug an application built for the .NET 4.0 runtime. The application resides on a network share and executed by a remote machine. However the application crashes each time during load because of a SecurityException raised by a permission demand in the System.Configuration.ConfigurationManager.GetSection() method. I have not checked if other permission demands in the base class library also cause a security exception but in all cases this shouldn't be happening with the new CLR. The application is running in full trust (checked it

“Assembly Same Simple Name already been imported” error

This is a CLR project. I'm importing two DLL files with the same name, quizz.dll (I rename the old version as legacyquizz.dll ) and I include the newer version as quizz.dll into a legacy converter test project. (The legacy converter project being tested only imports the old quizz.dll ). This is the error I'm getting . . . An assembly with the same simple name 'Quizz, Version=2.0.0.1, Culture=neutral, PublicKeyToken=null has already been imported.

Fatal Execution Engine Error (79FFEE24) (80131506)

由 烂漫一生 提交于 2019-11-30 11:22:18
I'm encountering problems with my .NET Framework 3.0 SP1 application. It is a C# winforms application communicating with a COM exe. Randomly either the winforms app or the COM exe crashes without any error message and the event log contains this entry: [1958] .NET Runtime Type: ERROR Computer: CWP-OSL029-01 Time: 11/25/2008 3:14:10 PM ID: 1023 .NET Runtime version 2.0.50727.1433 - Fatal Execution Engine Error (79FFEE24) (80131506) I could not find any useful information on the MS sites. Does anybody have an idea where I should start my investigation? tia I had this error, it (luckily) went

Implementing C# for the JVM

由 半腔热情 提交于 2019-11-30 10:05:47
问题 Is anyone attempting to implement C# for the JVM? As a Java developer, I've been eyeing C# with envy, but am unwilling to give up the portability and maturity of the JVM, not to mention the diverse range of tools for it. I know there are some important differences between the JVM and CLR but is there anything that is a showstopper? 回答1: There are very significant differences between the CLR and the JVM. A few examples: Java doesn't have user-defined value types Java generics is completely

Good samples of using Finalizers in C#

由 倖福魔咒の 提交于 2019-11-30 09:19:25
When I read a few articles about memory management in C#, I was confused by Finalizer methods. There are so many complicated rules which related with them. For instance, nobody knows when the finalizers will be called, they called even if code in ctor throws, CLR doesn't guarantee that all finalizers be called when programs shutdowt, etc. For what finalizers can be used in real life? The only one example which I found was program which beeps when GC starts. Do you use Finalizers in your code and may have some good samples ? UPD: Finalizers can be used when developpers want to make sure that

Will .Net 4.0 include a new CLR or keep with version 2.0

由 只谈情不闲聊 提交于 2019-11-30 09:10:06
问题 Will .Net 4.0 use a new version of the CLR (v2.1, 3.0) or will it stick with the existing v2.0? Supplementary: Is it possibly going to keep with CLR v2.0 and add DLR v1.0? Update: Whilst this might look like a speculative question which cannot be answered, the VS team appear to be releasing more and more info on VS10 and .Net 4.0 so this may very soon not be the case. (Info available here -> http://msdn.microsoft.com/en-us/vstudio/products/cc948977.aspx) 回答1: 4.0 is going to be another side
