Caught a BadImageFormatException saying
"Could not load file or assembly 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Core.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded."
This is the error message that I get when I try to run my project. Can someone help me?
It looks like you are trying to load a .net framework dll from a project running .net 1.1. Either that or you have a mis-match in running a x86 app vs a 64 bit dll, or trying to run a x64 app against a 32 bit dll.
Check with architecture you are running, and the target framework of the application.

I am using 64bit Oracle.DataAccess.dll (64-bit ODAC 11.2 Release 6 (11.2.0.4.0) Xcopy for Windows x64). Downloaded this package ODAC112040Xcopy_64bit.zip from
http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html.
I want to connect to Oracle 11g Database using the provider dll. I was able to install it successfully. However, when I use the dll in my Asp.net code, I am getting following error.
Exception Details: System.IO.FileNotFoundException: Could not load file or assembly 'Oracle.DataAccess, Version=2.112.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
My system is a Windows 7, 64bit machine. Using Visual Studio 2015. Even before the program execution reaches the function calls of Oracle.DataAccess.dll, I get this error as soon as the page loads.
Have seen many blogs with answers saying, 64-bit dll being used on 32-bit machine or 32-bit enabled IIS Website etc. My requirement is, need only 64bit dll to be executed on 64bit machine.
Please let me know how to fix the issue.
The error message says it is looking for Version=2.112.4.0, which is for .net 2 (and 3). The title of your post mentions .net 4.6, so you should be targeting Version=4.112.4.0 in your visual studio project
I'm trying to fix an intermittent exception:
System.BadImageFormatException saying "Could not load file or assembly
'dbpProject' or one of its dependencies. This assembly is built by a
runtime newer than the currently loaded runtime and cannot be loaded."
Apparently dbpProject refers to my database project.
Thinking that maybe one of the projects in my solution was to blame, I went and changed them all to target .NET 4. However, I'm still getting the BadImageFormatException, this time referring to one of my projects.
Additional weirdness: If I deploy to a web server, the application runs.
Possibly relevant -- the bottom of my error message says:
Version Information: Microsoft .NET Framework Version:2.0.50727.8689;
ASP.NET Version:2.0.50727.8670
Is there some way to fix IIS Express to run the right .NET version?
I receive the following error:
Cannot load assembly. Error details: System.BadImageFormatException: Could not load file or assembly 'file:...' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
This assembly is built with .Net Framework 4.0 and i made sure that all projects in my solution are also built with .Net Framework 4.0.
Any idea why i am getting the error? How can i check which frameworks are loaded with my application?
What is the main executable, i.e. the assembly responsible for deciding which version of the CLR is loaded? Note that it's not just a case of being built by .NET 4 - if your executable targets .NET 3.5 or lower, it will load in the .NET 2.0 CLR, and your .NET 4 assemblies won't load.
Hello I Had the same problem until i follow these hints: BadImageFormatException Class (section "Remarks")
In my case I was trying to load assemblies with call to umnaged code.
I've got a C# 2.0 project which is set to target 'Any Cpu', however it is referencing a C++ project that's building a 32 bit dll.
When I try to run my program on a 64bit machine I get the following error:
System.BadImageFormatException was
unhandled Message: Could not load file
or assembly TreeTMHook,
Version=1.0.2889.19619,
Culture=neutral, PublicKeyToken=null
or one of its dependencies. An attempt
was made to load a program with an
incorrect format.
How can I fix this?
Update
I want to be able to keep the main project as any cpu.
Thanks.
You'll need to build your .NET project as 32bit (x86 target) if you want it to correctly load a 32-bit DLL on a 64bit machine.
RE: Update:
If you want to keep your project as "Any CPU", you'll need a 32bit and a 64bit version of the DLL, and make sure the appropriate version is distributed with your app. If you can't build the other project as 64bit, you must build your .NET project as 32-bit only.
You will have to force your EXE project to run in 32-bit mode so it can use that C++ DLL. Project + Properties, Build tab, Platform Target = x86.
You may want to take a look at this article it explains why it is not possible, in short since you are dealing with pointers when accessing unmanaged code.
To keep you main project as Any Cpu, you need to supply both 32 and 64 bit version of the .dll - which should be possible, seeing as you're building it from source.
You then need to supply the executable with a manifest pointing it toward to right dll verion depending on platform.
Please use .net reflection and consume objects and its methods. Instead of direct 32 bit dll reference.
I am using a library (DLL) that uses the Oracle.DataAccess DLL to connect to the database.
I am doing in in C# .NET framework 3.5
When I attempt to compile, the compilation takes place, but the executable throws this error message.
Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture=
neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt
was made to load a program with an incorrect format.
Is there some way to get around this? What could be causing this to happen?
The dll for that ODBC is likely a 32bit only dll. Are you using this on a 64bit machine? If you are, IIS 7 has an option in the application pool that will allow you to "Enable 32-Bit Applications".
One possibility: Your programm is compiled with x64 or AnyCPU on a 64bit machine but the dll has been compiled with support for x86 only.
You can overcome this if you change the plattform of your Solution (or project) to x86.
I know you can force a 64bit Assembly to run as a 32bit app with:
corflags /32bit+ Oracle.DataAccess.dll
That works because the MSIL code is not bound to a processor architecture. However I never tried it the other way:
corflags /64bit+ Oracle.DataAccess.dll
so I can't tell if this works. And I propably won't work if the dll has unmanaged dependencies.
