I have an asp.net web application that uses an unmanaged 32 bit dll that I have successfully running on my development machine, but when I use web deploy to move the code to our test server, I start seeing BadImageFormat exceptions.
I set the target in visual web developer to x86 and both machines are running 64 bit os's (windows 7 and windows server 2008 r2). I'm not sure what other differences there could be causing the problem. Thanks for any help you can provide.
It turns out that there was a flag "Enable 32-bit executables" or something like this in the config files for the webserver that starts out false under iis 7.5
The error message was a total red herring.

I have a WCF Service hosted at my server and it is being consumed by client from another server.
I did few changes in the code and tried deploying the code after successful build.
Previously the application pool was set to 32 bit as true but the service opens correctly when i make that 32 bit as false.
Currently it is set to 32 bit true and working fine in QA but when i build it and deploy and run the service manually it fails at opening the oracle connection and throws this error "Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed"..
below is the link to the image of what settings i used in visual studio to build the solution.From the many project folder the yellow highlighted one is the startup project which is set to 64bit and all others as any cpu

I am not sure if i am doing anything wrong with the build for which the oracle gives this error while running the service.the application pool should be set to 32 bit
I have a .NET C# WebAPI application which is meant to run on IIS. The app loads an external 64 bit DLL. When I debug on VS2015 everything is fine, but I had to set this checkbox in order to make it work:
Now, I deployed the application on a Windows7 VM running IIS version 7.5 and I get the same error as if I haven't set that checkbox on VS2015. Is there any equivalent setting in IIS in order to force 64 bit mode?
I have my development environment as follow:-
Visual Studio 2012 Professional. version 11.0.50727.1
Windows Server 2012 R2.
asp.net mvc4 web application.
now since last week i am facing these problems:-
when i run my asp.net mvc web application inside visual studio, i will receive the following error, when i access my asp.net MVC home page:-
500 Internal Server Error
after many runs, the CPU will reaches 100% and my development machine will automatically get restarted. now i check with our system admins and they mentioned that the VM got restarted because of high CPU...
so i am not sure if the problem is within VS 2012 , or within the VM itself.. baring in mind that the VM host some test applications inside IIS,, and we can access these application without any problem. also i can open the sql managemnt studio and work with the DBs without any problem. so before asking to expand the DEV machine specifications to avoid high CPU , i want to make sure that the problem is not within Visual Studio itself ??
here is 2 screen from the server manager after the VM got restarted :-
now i am not sure how i can fix this?
Thanks
The 500 Server Error is the standard error report from IIS if an MVC application throws an unhandled exception. So your code inside your MVC application is faulting somehow.
If this occurs you would normally run your site in debug mode in Visual Studio to trap the exception and debug out the problem. I have not idea what your application actually does but I can speculate the following possible cause;
1) IIS receives your call.
2) The MVC code generates a high CPU load doing some faulty code.
3) The calling application times out its HTTP call, and calls again.
4) Another IIS Instance is created to deal with the new HTTP Call (depends on your IIS Setup)
5) The second IIS instance does the same as (2) but in a different thread, causing more resource consumption.
Eventually you get a 500 server error as one of your IIS instances times out or throws and exception. Your "helpful" sysadmin kills your VM.
The killing of the VM is entirely uneccessary - IIS has perfectly adequate safeguards against runaway IIS processes, including IIS Application Pool timeouts, automatic IIS Application Pool recycling, IIS Application Pool CPU Throttling, and IIS Application Pool maximum memory usage. All of these configuration options prevent the operating system from being destabilised by a runaway IIS application.
Without any insight into what your website does in the background we cannot go any further, but if you mod your question and give some of the MVC code its possible something might be spotted.
I had a similar error with Visual Studio 2013. The error turned out to be one my Addins. If you are using add-ins, try disabling the suspected plugin from the Tools --> Add-in Manager..., then restart Visual Studio. If you are using extensions try reviewing those as well from Tools --> Extensions and Updates...
You can optionally choose to run Visual Studio in Safe Mode which will essentially do the same thing but will disable all plugins. devenv.exe /SafeMode
Hope this helps.
I had some similar issue in Windows Server 2012 running Visual studio 2012.
Upgrade your Visual studio and Windows server both. It will solve the issue
I new to ASP.NET development and I have managed to deploy VirtoCommerce to my local machine IIS (windows 8.1) following the documentation on http://docs.virtocommerce.com/display/vc2devguide/Deploy+web+applications+to+dedicated+server .
When I tried to deploy it in Azure VM running Windows server 2012, I got the following error when I tried to run the frontend page. The dll mentioned below is definitely in the /bin folder of the store.
Server Error in '/' Application.
Could not load file or assembly 'LibSass.x64' or one of its dependencies. An attempt was made to load a program with an incorrect format.**
I followed the link
Could not load file or assembly 'LibSass.x64' or one of its dependencies in VirtoCommerce but found no luck. What did I miss on this deployment ? Any help is much appreciated, thank you.
Are you running 64 but machine and IIS Application Pool as 64 bit? If not, make sure to go to IIS and configure pool settings to run as 64 bit process. The easier approach will be to follow the guide here: http://docs.virtocommerce.com/display/vc2devguide/Deploy+from+GitHub+to+Microsoft+Cloud+Azure which will setup Virto Commerce as a website in IIS with all correct configuration for IIS. You can then update it manyally by simply uploading site through FTP if you want. You can also clone the repository on GitHub and that way your azure site will auto update on every checkin.
I was able to reproduce this error on a clean Windows Server 2012 Standard. It turned out that Libsass.Net requires Visual C++ Redistributable Packages for Visual Studio 2013. After installing the vcredist_x64.exe the error has gone.
I am having problem getting the MS Visual Studio Remote Debugger to connect to my local IE instance as it is running as a 64-bit rather than a 32-bit process.
Every time I try to run it currently in Visual Studio I get the
The 32-bit version of the Visual Studio Remote Debugging Monitor (MSVSMON.EXE) cannot be used to debug 64-bit processes or 64-bit dumps".
error.
Investigating a bit, I think I have narrowed it down to the web asp service being run as a x64 process rather than a x86 (which both Visual Studio, and the silver light application are running as). I confirmed it as running as a 64-bit process by trying to "attach" visual studio to the process when the application was running in the ASP.Net Development Server.
In short: Is there a setting I am missing somewhere to force Visual Studio to run the ASP.Net service as a 32-bit process? I have read about using a variable in the web.config application pool to use 32-bit (via the enable32BitAppOnWin64 config option), but it seems to only work in IIS, not ASP.net Dev server.
Any thoughts?
Edit For Clarity:
I am running Windows 7 64-bit, Visual Studio 2010 (which is running as a 32-bit process). Currently it is launching ASP.NET Development Server (not IIS) to host the back end web service. I am hoping I can simply "fix" this via a setting, but if not my backup would be to run IIS Express.
If I'm understanding you correctly you should do this:
IIS Manager/Application Pools-> choose the correct pool for your application/Advanced Settings/Enable 32-Bit Applications->set it to true !
I had problem like this in the past which cost me 1-2 days, hope this helps !
Check also Project/Properties/Build/Platform target->this should be Any CPU
