I'm building a VS 2012 WPF app targeting .NET 4.5 Any CPU on Win7. I notice in the debug output window that the 6 system assemblies beloweach take ~3-4 seconds to load. This delay occurseach time I run the app. I ran ngen update and rebooted, but it hasn't helped. The total app startup time is still about 24 seconds. The app includes about 16 other assemblies, including Unity, System.Web, System.Transactions, Extended WPF toolkit, System.Data.OracleClient (apparently EF requires this even if you aren't using Oracle), but all of them load very quickly. I've read various blogs about improving cold/warm boot times, but haven't found anything applicable here.

Q1. Why are some in GAC_MSIL vs. GAC_64?

Q2. Why are the version numbers 4.0_4.0.0.0 vs. 4.0.30319?

Q3. How can I speed it up?

Thanks!

We have follwoing queries regarding "user Account Context"

1) What is the meaning of "user account context"?

2) What is the meaning of "the application runs under a user account context"?

3) What is the meaning of "application that runs under a user account context and when no user profile is associated with the user account context"?

4) We came across one Hotfix from Mocrosoft as "A .NET Framework 2.0 application that runs under a user account context when no user profile is associated with the user account context may crash, or you may receive an access violation error message" at"http://support.microsoft.com/kb/913384"

    We came across the mentioned Hotfix while searching the solution to our application which crash randomly. The Symptoms mentioned in the Hotfix are matching with Symptoms of our crashing application.

    We are testing our VS2005 VB.Net Application with SQL 2008 R2 as Database Application on Whindows 7 Machine. The Windows 7 has default Framework 2.0 - SP2 and 3.5 - SP1.

    i) The mentioned Hotfix applies to only Framework 2.0

   ii) The problem for which Hotfix released solved in Framework 2.0 - SP1 / SP2. 

   iii) The problem for which Hotfix released will not occured in Windows 7.

   iv ) The mentioned Hotfix is not appies to Windos 7

Our above mentioned understandings are correct?

5) we are STILL facing the crash problem mentioned in Symptoms of the Hotfix in Windows 7 machine. What are the probable root causes for same? We are trying to test application on newly installed Windows 7 machine. Is it correct step?

6) Is there any way to run the application without user account context ?

Thanks in advance...

I'm having difficulty subscribing to events from an unmanaged C++ class in a managed C++ class. I'm a C# developer wrestling with Interop and C++ is an alien environment so I'm possibly missing something obvious.

I have to have an unmanaged C++ class because the SDK I'm using only supports this; the managed C++ is a wrapper allowing access from the C# project that I'm writing the rest of the project in.

I can subscribe to events from managed classes and believe that I need a delegate because the unmanaged code needs a pointer it can understand not the address of a managed function. C3374: can't take address of 'function' unless creating delegate instance was very useful in this respect.

But I cannot get the following code to compile or function - the code to subscribe to the events is in ManagedNS2::ManagedTarget::Init() and my attempts are preceeded with the compile error generated.

#include "stdafx.h"
#include <iostream>

using namespace System;
using namespace std;
using System::Runtime::InteropServices::Marshal;

namespace ManagedNS1
{
	public ref class ManagedSource
	{

		ManagedSourceEvent();
	}

			MyEventDelegate^ del;
			ManagedTarget();
			~ManagedTarget();
			void EventHandler1();
			void EventHandler2();
			void Simulate();
			void Init();
	};
}
	
	ManagedNS2::ManagedTarget::ManagedTarget()
	{
		unmanagedSource = new UnManagedNS1::UnManagedSource();		
	}

	ManagedNS2::ManagedTarget::~ManagedTarget()
	{
		delete unmanagedSource;
	}

	void ManagedNS2::ManagedTarget::Init()
	{
		//subscribe to events from managedSource - this works
		managedSource.ManagedSourceEvent += gcnew ManagedNS1::ManagedSource::ManagedSourceEventDelegate(this, &ManagedNS2::ManagedTarget::EventHandler1);

		//subscribe to events from the unmanaged source - without delegate gives incompatible event (because unmanaged code needs native pointer it can understand; not an address of a managed function)
		//__hook(&UnManagedNS1::UnManagedSource::UnManagedSourceEvent, &unmanagedSource, &ManagedNS2::ManagedTarget::EventHandler);

		del = gcnew MyEventDelegate(this, &ManagedNS2::ManagedTarget::EventHandler2);
		IntPtr pMyEventDelegate = Marshal::GetFunctionPointerForDelegate(del);
		//improper syntax for specifying event handler in __hook/__unhook
		//__hook(&UnManagedNS1::UnManagedSource::UnManagedSourceEvent, &unmanagedSource, pMyEventDelegate.ToPointer());
		//invalid argument for delegate constructor; delegate target needs to be a pointer to a member function

		//invalid argument for delegate constructor; delegate target needs to be a pointer to a member function

	}

	void ManagedNS2::ManagedTarget::EventHandler2()

	}

	void ManagedNS2::ManagedTarget::Simulate()

i received a ".NET Runtime 2.0 Error" with an Event ID of 1000 that i don't understand and have been unable to reproduce. here is the error message:

Faulting application serializer.exe, version 4.0.2578.32199, stamp 45b55c7e, faulting module mscorwks.dll, version 2.0.50727.42, stamp 4333e7ec, debug? 0, fault address 0x001066ef.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

the application that had the error is an automated application that runs every night so i was not around to see it crash. any suggestions as to what may have caused it? also, what is mscorwks.dll?

I made a console application in Visual Studio that reads a flat file from our customer and updates the oracle database depending on the received data.

I use streamreader / writer to read and write some files.

When I run my exe file locally everthing works fine.  When this exe is run on the application server this gives following error message :

Can someone help me with this issue.

I am pretty unexperienced in developing VB applications

Why using DynamicMethod allow to change reference without any types check? Is this known and explainable thing?

using System;
using System.Reflection;
using System.Reflection.Emit;

namespace Dynamics
{
	internal class Program
	{
		private static void Main(string[] args)
		{
			var a = new A();
			a.Name = "Name";
			Console.WriteLine(a.Name.GetType().Name);

			PropertyInfo pi = a.GetType().GetProperty("Name");

			DynamicMethod method = new DynamicMethod(
					"DynamicSetValue", // NAME
					null, // return type
					new Type[] 
                            {
                                typeof(object), // 0, objSource
                                typeof(object), // 1, value
                            }, // parameter types
					typeof(Program), // owner
					true); // skip visibility

			ILGenerator gen = method.GetILGenerator();
			gen.Emit(OpCodes.Ldarg_0);
			gen.Emit(OpCodes.Ldarg_1);
			gen.Emit(OpCodes.Call, pi.GetSetMethod(true));
			gen.Emit(OpCodes.Ret);			

			SetValue setMethod = (SetValue)method.CreateDelegate(typeof(SetValue));

			int val = 123;
			setMethod(a, val);
			Console.WriteLine(a.Name.GetType().Name);

			A anotherA = new A();
			anotherA.Name = "Another A";
			setMethod(a, anotherA);
			Console.WriteLine(a.Name.GetType().Name);
		}

	public class A

Hi 

Anyone has any idea on how to solve this problem 

Error System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Hello,

It seems the in ability to load of Portable Libraries as well as Silverlight libraries becoming more problematic everyday.

I am one of the contributors of language called Nemerle. http://nemerle.org/ It is a 10 years old compiler basically it uses System.Reflection.Emit to read the types and generate the IL code. The first major problem we hit at the emergence of Silverlight. Since silverlight and portable libraries use a different version of mscorlib (2.0.5.0) and since CLR has some limit of only loading 1 instance of mscorlib, we were unable to generate silverlight libraries. Mono on linux people and boo compiler (probably somewhere on the road F# too)  and other compilers using System.Reflection.Emit also encountered same problems.

Some people choose using IKVM.Reflection.Emit some others tried Mono.Cecil, and Microsoft introduced CCI (which is windows only and relies on COM IIRC)

At that time Nemerle developers simply gave up working on this issue , we thought we can go on without silverlight since Nemerle is a better language than both C# and F# :)

However these days more and more libraries started using Portable Class Libraries for the sake of better portability which is good but also causing lot of problems on the otherside.

You may consider Nemerle as a mostly unknown language with insignificant number of users. (I bet you haven't heard it before)  but these problems are not limited to Nemerle.

I've seen problems like older versions of .NET Framework 4.0 can't deal with PCL, or another example is that there are cases where XAML designer in VS 2012 with PCL . Also Sandcastle tool have problems with it.  I can see this is getting more and more annoying.

Another example would be from .NET 4 or .NET 4.5 create a console app try some code like this

            var a = System.Reflection.Assembly.ReflectionOnlyLoadFrom(@"c:\mscorlib.dll");
            Console.WriteLine(a.GetExportedTypes());

I assume you copy mscorlib 2.0.5.0 to some known location like C:\

This code simply fails with a NRE because it cannot find the parent of System.Object in the PCL version of mscorlib.

Note that these are just examples not the real problem. I know you will say "unfortunately current version of CLR cannot handle this". That's fine. But what I'd like to hear is that you may try to fix this in the future versions so that SRE and Reflection can work someway properly.

This is all IL code we are talking about it should be possible to merge these differences in some more transparent way. Otherwise future problems can produce a lot of headache for everyone

Hello,

I'm pretty sure this is straight forward I just can't seem to get it working.

I have a service called serviceX and I want to control it from another application.  The "control" is simply checking the ServiceController.Status field and calling ServiceController.Start().

The exception i get is:-

Keith.

Dear All,

We are working VS2005 vb.net multi threaded application with MS SQL 2008 R2 as a database. The application we are testing on Windows 7 (32 Bit) machine. Currently Following frameworks are installed.

1) 2.0 - SP2          2) 3.0 - SP2          3) 3.5 - SP1

The application is running correctly as per client requirement. But sometime it got crashed with message"a problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available".Till date, the maximum time for which application run without crash is 1 day.

We observed following two consecutive logs in Event Viewer > Windows Logs > Application

1) Event 1023, .NET Runtime

   .NET Runtime version 2.0.50727.5472 - Fatal Execution Engine Error (7216F7AE) (80131506)

2) Event 1000, Application Error

    Faulting application name: Our Application Name.exe, version: 1.0.0.0, time stamp: 0x51f7b33b

    Faulting module name: mscorwks.dll, version: 2.0.50727.5472, time stamp: 0x5174dd69

    Exception code: 0xc0000005

    Fault offset: 0x000a1919

    Faulting process id: 0x%9

    Faulting application start time: 0x%10

    Faulting application path: %11

    Faulting module path: %12

   Report Id: %13

To resolve the problem basis our internet search and couple of queries which we posted, we carried out following exercise

• Verified the framework installed from tool “http://blogs.msdn.com/cfs-file.ashx/__key/CommunityServer-Components-PostAttachments/00-08-99-90-04/netfx_5F00_setupverifier_5F00_new.zip” We not found any issue
• We came across the Hotfix from Microsoft at "http://support.microsoft.com/kb/913384". The title of Hotfix is “HOTFIX: A .NET Framework 2.0 application that runs under a user account context when no user profile is associated with the user account context may crash, or you may receive an access violation error message”.

It talks about the same error which we are facing, which includes two error messages in event viewer with Event ID: 1023 and 1000. We also observed mentioned two event id as mentioned above. We download the Hotfix and try to install. But we came across the error message as “The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program”

Our queries:

1 ) Which are the other probable cuases of the problem? How to resolve them?

2) The hotfix not installed because framework 2.0 - SP2 already installed. Is our understaning correct?

3) As defination of the Hotfix which we downloaded, do we need to run application without user account context? If answer is Yes, then suggest how to carry out same.

Thanks in advance.....

Hi there,

My scenario is: there is a asp.net application. a few end-users get very slow response. I need to know the time period of every steps/stack: how much time the IIS dispatch the request, how much time the business logic execute, especially, every call stack execute time period, in my scenario, there is a WCF service to provide some data. I also need to know this time period.

Does anyone can give me some related articles?

Thanks.

Hello,

I have several production dumps where client is reported to just hang. Based on 'some' analysis, There are several threads (almost 3 to 4) whose top of the stack is clr!CLRSemaphore::Wait?

Can someone help in  understanding the construct? What does this operation account to the thread activity/health?

I did not find any helpful documentation to help understand this kind of call stack.

Thank you...

Is there a problem to call WRL/ WinRT APIs from a DLL? If yes, what, why? Is there a workaround? Why does my code work sometimes but crash sometimes? Call stack is as displayed below:

Hi

     Question about formatting the datetime string by passing dateformat and locale ID using ToString() function, 

1. How many .net supported date formats available?

2.  Where do I get the list of formats supported by each locale?

3. Is it possible that any particular locale doesn't support any specific format?

Thanks

We are working VS2010 vb.net multi threaded application with MS SQL 2008 R2 as a database. The application we are testing on Windows 7 (32 Bit) machine which has Framework 4.0 installed.

While testing sometimes (twice a day) we came across 'Application Crash' situation withtwo consecutive logs in Event Viewer > Windows Logs > Application

Earlier we used to faced the similar issue on VS2005 with bit higher frequency ( 5 times a day) . To overcome same we decided to upgrade code to VS2010.

While finding the solution we carried out following activities:

1) we came across the Hotfix at "http://support.microsoft.com/kb/2640103". We installed same on the machine on which we are carrying out the testing. After installing Hotfix also we are facing the problem. We are not yet installed same on the machine on which we are compiling the code. Now we will install sameon the machine on which we are compiling the code and will carry out the testing.

2) disabled concurrent garbage collector using following content of config file

Our Queries :

1 ) do we need to install the hotfix on machine on which we are compiling the code as well as the machine on which we are carrying out the testing?

2) Installing hotfix only on machine on which we are carrying out the testing will create any issue?

3) Which are the other possible resons for which we might face the mentioned problem? How to resolve same?

Thanks in advance.....

I'm trying to utilize an old application framework from managed C# code but I don't understand how to marshal the safearray argument which is forwarded to the managed code. Here is a code snipped describing how the managed code is called:

try {
    _ObjectHandlePtr pObjectHandle; 
    _ObjectPtr pObject; 
    _TypePtr pType;
    SAFEARRAY* psa;// Create an instance of a type from an assembly
    pObjectHandle = pDefaultDomain->CreateInstanceFrom(L"ClassLibrary1.dll",   // no path -- local directory
                              L"ClassLibrary1.Class1");
    variant_t vtobj = pObjectHandle->Unwrap();                   // Get an _Object (as variant) from the _ObjectHandle
    vtobj.pdispVal->QueryInterface(__uuidof(_Object),(void**)&pObject); // QI the variant for the Object iface
    pType = pObject->GetType();                             // Get the _Type iface
    psa = SafeArrayCreateVector(VT_VARIANT,0,1);               // Create a safearray (0 length)
		LONG index = 0;
		variant_t task = msg.task;
		SafeArrayPutElement(psa, &index, &task);//variant_t vtret;
    hr = pType->InvokeMember_3("Test",                           // Invoke "Test" method on pType
               BindingFlags_InvokeMethod,
               NULL,
               vtobj,
               psa);
    SafeArrayDestroy(psa);                                  // Destroy safearray
  }catch(_com_error& error) {
    _tprintf(TEXT("ERROR: %s\n"),(_TCHAR*)error.Description());goto exit;
  } 

The msg.task is a plain unsigned int for testing purpose only. But how do I catch the psa safearray structure in the argument of the managed method (ClassLibrary1.Class1.Test)?

We have an old .net 2.0 web application.  We need to make some code changes to it so I installed Visual Studio 2005 on my Windows 7 computer and configured everything I think needed to be configured.  When I try to run the application, the w3w worker processes crashes each time (so far I was able to identify two places where this happens).  Here is what the Event Viewer shows:

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8

I don't have much experience analyzing dump files but I created a crash rule using Debug Diagnostics Tool 1.2 and then when I opened the dump file using windbg.exe this is what's in it:

I have search the internet for the error message I'm getting and I have found 2 different reasons people would get a similar crash:

- reason 1 was when the app had some infinite loop in it - I don't think this is my case since our application has been in production for over 6 years now not causing any problems

- the second reason was permissions related e.g. when the app is trying to write to some file that it has no permission to write.  That is a possibility since I am setting it up on a new computer.  However, one place where this crash occurs is when a user selects a value from a drop down list, and the app is supposed to retrieve data from the database and populate another drop down list based on that.  However, the crash does not always happen in this place.  Only sometimes.  And the connection to the database definitely works since everything works fine in many other places in the app.

Any help or troubleshooting ideas will be greatly appreciated.

thanks,
