This is the strangest programming issue I have seen in a long time.
I am using Microsoft Visual C# 2010 Express, C# and .NET 2.0 to develop an application. This application references a couple of dll/assemblies (those dlls are all generated on my machine).
Below is part of the code (it is all basic stuff):
public class PowerManagement
{
[TestCase]
public void PrepareTest(){
// Configure according to pre-conditions
Preconditions precondition = new Preconditions();
precondition.SetupPreconditions();
...
}
[TestCase]
public void PerformTest(){
TestcaseData testcaseData = new TestcaseData();
// Set Trigger and perform check
switch (testcaseData.triggerNumber){
case (1):
if ((new Trigger1(testcaseData)).Validate() != 1)
Report.TestStepFail("failed");
break;
...
case (4):
if ((new Trigger4(testcaseData)).Validate() != 1)
Report.TestStepFail("failed");
break;
default:
Report.TestStepFail("Not yet implemented");
break;
}
}
}
This application is then generated into a dll from Visual C# 2010 Express and used elsewhere and all is fine. The problem surfaces when I add another case to the switch-statement above (see below)
...
case (4):
if ((new Trigger4(testcaseData)).Validate() != 1)
Report.TestStepFail("failed");
break;
case (5):
if ((new Trigger5(testcaseData)).Validate() != 1)
Report.TestStepFail("failed");
break;
default:
Report.TestStepFail("Not yet implemented");
break;
I can still build without a single issue and generate the dll but when I use the generated dll I get the following error:
A .NET exception (InvalidProgramException) occured in the module PowerManagement
Error message: Common Language Runtime detected an invalid program.
Throwing method: PowerManagement.PerformTest
(the issue happens even if I copy case(4) and paste it as a new case, so it has nothing to do with Trigger5-class)
What is happening here? I have looked through the other InvalidProgramException and Common Language Runtime in Stackoverflow but none seemed related.
I know this issue is strange so please let me know and I will provide more information. I am using a 64-bit Windows 8 machine, if that matters. I have already checked for any updates on VS and .NET updates. I havet also regenerated all the dlls a couple of time ans also created the solution from scratch a couple of times.
Just wanted to add my experience for this...
In my case, I am hosting my C# Web API on Azure and I encountered this message when trying to log in to my API.
I had to go into my Azure management portal (portal.azure.com), go to App Services, choose my Web API program and click Restart from the Overview screen.
After this, the program worked as normal again.
Did not find any further clues in my logs.
I finally managed to solve this issue.
I unchecked code optimization in C# Express and that solved the issues. Still the weirdest thing, but since we are using old tools and framework we can not really blame anyone.
Try enabling 32-bit applications in your application pool advanced settings.
I had this problem after upgrading to Visual Studio 2017 v15.8.6. The problem went away when I removed the assemblyPostProcessorType attribute in the compilation tag in web.config.
According to MSDN: "Generally this indicates a bug in the compiler that generated the program."
I would start by making sure you have all the updates installed on Windows, .NET and Visual Studio.
You should also check out Q312544 on Microsoft Support.
I've occasionally encountered this error after a deployment to an Azure WebApp using MSDeploy. The error has always disappeared after redeploying for a second time.
Our build and deployment are two different steps, the the redeployment is sending over the exact same files each time - this suggests the problem is not uniquely a compiler issue as suggested elsewhere in this question's responses.
Could be a bug in MSDeploy, or in the version of IIS used for WebApps in Azure perhaps...
Such problem could be caused by bugs in tools manipulating the IL of assembly after compilation, for example if you are using Fody and its plugins. At least there is a bug in Fody MethodDecorator which causes such effect, see
https://github.com/Fody/MethodDecorator/issues/8
If you are having this issue specific to Azure Web Apps - check for installed extension Microsoft.ApplicationInsights.AzureWebSites - or it's friendly name Application Insights extension for Azure App Service and remove it via kudu.
We found this extension was potentially interfering with msdeploy pushes - there was a process snapshotholder_x64.exe running under the IIS w3wp.exe process. Someone likely enabled this extension via the azure portal.
If your issue pertains to a web api dotnetcore deployed to an azure app then this could be caused by application insights. Setting the application insights at the blade level should fix the problem. Also note that there seems to be an unresolved issue with setting it at the blade level as recommended settings vs basic. Basic being the value that works.
Running into this issue deploying a Web Api as an API App on Azure. An initial request to any endpoint would result in the expected response; however, subsequent requests would return the same Common Language Runtime error. I figured out the problem started when I enabled Recommended collection level on the Application Insights blade on my web app. I set recommended and enabled all radio buttons. Reverting this change stopped the error. For reference, the API I am running is running Microsoft.ApplicationInsights 2.8.1

I was doing some powershell automation in a console application using .net core 3.0 when i started receiving this error. I guess .net core is not compatible with System.Management.Automation so i changed it to .net framework 4.7, everything worked well after that
I resolved this issue by doing the following:
Rename C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Team Tools\Performance Tools\vsinstr.exe to C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Team Tools\Performance Tools\vsinstr.exe.broken
Rename C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Team Tools\Performance Tools\vsinstr.legacy.exe to C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Team Tools\Performance Tools\vsinstr.exe
Rebuild the solution
-uncheck "code optimization" (referenced dlls included)
-Upgrade to .net framework 4.6
Out of nowhere we started getting XXX webservice Exception , System.InvalidProgramException: Common Language Runtime detected an invalid program.
Copied compiled website to a different environment - works just fine.
Copied to a different server - works just fine.
I noticed that this exception started when server was reset (either rebooted or app pool reset). When researching this issue, I noticed comment by Brian Reichle on Jun 6 '16 at 12:33
I would expect a bitness mismatch to result in a
BadImageFormatException rather than the InvalidProgramException
described in the question.
I was not familiar with InvalidProgramException exception but I was familiar with BadImageFormatException and the symptom is very similar to the one I get with BadImageFormatException issue. I can't say 100% why either exception happens, current running theory is its a 32-bit application running on a 64-bit machine, but we couldn't prove it nor could we perma-fix it. Enabling 32-bit applications on app pool did not fix the issue.
The only fix we know of, albeit temporary, is to simply recycle App Pool. No need to recompile or anything. Luckily, this happens not too often, maybe once a month or two.
I just ran into this problem myself. Even though VS created the virtual directory for me, it had vb as the default language, but I have a C# application. Changing this setting solved it.
This is an interesting exception that i came across while hosting on IIS. I solved it after finding out that my .NET Framework version on IIS was different from the .NET Framework version that my project was using. Please note if you happen to have other referenced projects/ddl(s) make sure you update their .NET Framework version too.
In my case it was Hasp protection (google: hasp sentinel protection key) SW which ruined the dlls.
To share my experience: had the same issue on x86 computer with my WindowsForms app, found out I've forgotten to copy .exe.config file with all dll redirections, after that everything worked like a charm.
In my case, the exception was caused by datadog tracer after upgrading from 3.1 to NET 6, by upgrading to their latest version, the issue was fixed.
Here is the diff in my dockerfile.
-RUN curl -LO https://github.com/DataDog/dd-trace-dotnet/releases/download/v1.12.0/datadog-dotnet-apm_1.12.0_amd64.deb

I've designed a WPF C# application using Visual Studio 2012. The application, which is simple enough, runs fine on my Windows 8 machine using the ClickOnce deployment method. The datagrid displays the content from a SQL Server database and performs all of it's other functions just as I've designed it to, but when I attempt to install it on a Windows 7 machine it immediately crashes and I'm not sure why. The Windows 7 computer I'm trying to install the application on has .NET 4.5 running on it, but is there anything else that computer needs to have installed on it in order to run applications developed with VS 2012. This is my first attempt to install an application developed with VS 2012 on a Windows 7 machine, so I'm not sure if there's another step that I'm missing here. Any help you guys can provide would be greatly appreciated. Thank you.
The message you stated "The application has stopped working and that if Microsoft has a solution..." is an indicator of one of the following:
The Framework is disabled; though 4.5 is installed several root instances are built on the foundation which are apart of Framework 2.0. This particular Framework can cause issues for 3.0, 3.5, 4.0, and even 4.5.
The System.EnterpriseServices.dll is damaged in the Framework. Which needs to be connected back to the Global Assembly Cache (GAC).
And another common issue is the machine.config file log in the Framework Folder can be corrupt and needs to be replaced with a valid one.
There are others that can occur within the System Policy Folder as well, which may require you to use the .Net Cleanup Tool and reinstall the Framework. But before you do any troubleshooting you should go to the Event Viewer and get details of what is going on.
Try these steps first for me:
Windows Key + R
When the run prompt appears type: appwiz.cpl
Go to the left hand side: Turn Windows Features On or Off
Turn Framework 3.5 on if it isn't already; if it is already on go to Step 5.
Turn off the Framework; then reboot.
Once rebooted follow steps 1-4 again.
Now at this point I would suggest trying the application again. If it fails try this:
Open Start
Type 'cmd' in Search
Right Click and Run as an Administrator
Type %windir%\Microsoft.Net\Framework\v2.0.50727\ngen.exe update
Then type: sfc /scannow
The Native Regeneration tool will try to repair the Framework back to a factory state; the System-File-Checker will attempt to fix any errors indicated in Windows. If it can't it will say 'it found integrity violations'.
Those are the steps I would do for general support; but you really should try and locate an error message. As the Framework can become a huge ordeal to cleanup and fix. If you provide more information I will revise my response to help address it.
Hopefully that helps.
I've copied over the content of the Debug folder on a Windows 7 VM and a Windows Vista laptop. Both had Dot Net 4.5 installed. All assemblies are set to copy local and AFAIK I don't reference anything not in the application folder. When I run the app on the two different developer computers (one Win8, one Win7) it runs fine as it does when running it in Visual Studio (F5).
Not so on the deployment computers. The problem is that I get no error message. Absolutely nothing happens after I double click the executable on the non-development machines.
I tried starting it in WinDbg.exe and got this output: http://pastebin.com/43PbwyGx
So how to I go about debugging this to find out what's missing?
looking at your WindDbg dump you have an 2nd Chance Execption of CLR exception - code e0434352 (!!! second chance !!!).
I would look at this article by Igor Dvorkin, Why do I keep getting exception code e0434352.
Where he discusses it being a generic exception and how to fire up the cdb to find what the underlying exception was.
He also links to another of his blog posts, Finding CLR exceptions without visual studio where he describes using cdb.
Are the dev machines 64-bit but the other machines 32-bit? If this is the case and you're building as AnyCPU, then all your references also need to be AnyCPU (or match the platform your program is running under). If you build as x64, then I think all your references need to be x64 as well, and the same goes for x86.
Usually the exception you'll see in this case is a BadImageFormatException (it's also typically logged to the Windows Application Event Log with a source of Side By Side Configuration).
Also, just an FYI, sometimes you might be able to find the exception in the Windows Event Log. I think it's the Application Log, and I think the Source is usually .NET Runtime, or Application Error. The details may include both the actual exception as well as a stack trace.
I'm not sure what conditions need to be true for these errors to be logged, but it's something to consider.
Completely random and suddenly our application crashes on its production environment. The application runs on Windows XP and .net framework 3.5 sp1. In the application we provide a WCF service and we use the serial port.
When the application crashes it leaves messages in the application log:
.NET Runtime version 2.0.50727.3625 - Fatal Execution Engine Error (7A0BC59E) (80131506)

On our test environment we do have similar problems.
On the internet I find several identical problems, all mention hot fixes or reinstalls. But I want to know what happens and do not want happens. Does anyone knows what happens and how we can fix it?
[edit]
Besides the application also Sophos antivirus and MySql is installed.
[edit 2]
In our application we use a C-library wrapped in a .net package. We use the library in more applications and in those it does not give the exceptions.
[edit 3] Cannot answer my own question
Well I found something:
http://support.microsoft.com/kb/959209/en-us
958481 List of the issues that are addressed by the Application Compatibility Update for the .NET Framework 2.0 Service Pack 2
In the .NET Framework 3.5 SP1, because of the changes that are made in
checking a NULL value to support address space layout randomization
(ASLR), a failure case causes an access violation in the runtime. This
access violation manifests as an ExecutionEngineException exception.
Additionally, the process is terminated.

i suggest you use MS Debugging tools for windows's AdPlus utility to take a full dump of the process when it crashes and then use WinDBG to see what happend. (using !threads , !clrstack ,!PrintException).
I have one windows application built using C# and .net framework 2.0 and its installed on Windows Server 2003.
I have tested application on my machine and it works perfectly on my machine. Only difference between two machines is that, my machine has Windows Vista OS and machine on which error occured has Windows Server 2003 OS.
When I start application, it works correctly for some time but then gives one error as
Faulting application ,
version ,faulting
module kernel32.dll,version 5.2.3790.4480, stamp , debug? 0. fault address 0x000bef7.
Source : .NET Runtime 2.0 Error
Category : None
Event ID : 1000
Does anyone knows why this error is coming? I googled for this error but most of the solutions were for either explorer.exe or internet explorer.
Use windbg or adplus to attach to the process and get the process crash dump. This would help you to identify the offending part of the code with symbols loaded. In most cases, it shows the last exception and hence gives a very good view of what could have gone wrong.
