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'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 have a .NET application compiled on a certain version of the .NET framework.
At runtime it should be able to dynamically load some assemblies to be used as references for some C# code to be compiled and emitted in a new assembly.
I would like the application to be able to load some basic assemblies, such as mscorlib, System, System.Core, etc, without having to specify their physical path or version. I would like the assemblies of the same framework version as the application to be loaded.
Class System.Reflection.Assembly has many methods to load assemblies (many are obsolete/deprecated!), but I don't manage to find a suitable one.
Is there a clean way of loading framework's assemblies with currently executing framework version?
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've a C# class with CorePoll namespace, I compiled it to .DLL file and put it inside bin folder of website. But I cannot use it. Imports CorePoll returns Could not load file or assembly 'CorePoll' or one of its dependencies. An attempt was made to load a program with an incorrect format.
It's my class file in C# http://pastebin.com/JkdrnXyT
The message An attempt was made to load a program with an incorrect format., typically comes from mixing 64/32 bit environments. When you build your .DLL, make sure to select Any CPU as the Target CPU int the build settings. That way, the DLL should work no matter if the website is running 32 or 64 bit. But be aware, the message also states Could not load file or assembly 'CorePoll' or one of its dependencies., meaning that if you've referenced other libraries in your DLL, they could be failing to load as well.
Edit: After looking at the documentation, another potential cause of this exception is mixing projects built with different versions of the .Net Framework. Is this possibly causing your error?
Components have been created using different versions of the .NET Framework. Typically, this exception occurs when an application or component that was developed using the .NET Framework 1.0 or the .NET Framework 1.1 attempts to load an assembly that was developed using the .NET Framework 2.0 SP1 or later, or when an application that was developed using the .NET Framework 2.0 SP1 or .NET Framework 3.5 attempts to load an assembly that was developed using the .NET Framework 4. The BadImageFormatException may be reported as a compile-time error, or the exception may be thrown at run time.
None of answers helped me, I converted the C# code to VB.NET and used it with no problem, thanks for your time.
I am trying to use the Mono.TextEditor assembly with .NET Framework 3.5 in GTK#. But I keep getting System.BadImageFormatException
Could not load file or assembly 'Mono.TextEditor, Version = 1.0.0.0,Culture = neutral,
PublicKey Token = null' or one of its dependencies. This assembly is built by a runtime
newer than the currently loaded runtime and cannot be loaded.
The MonoDevelop version I am using (Mono.TextEditor is an addon of MonoDevelop) is definitely built by .NET version 3.5. Any Help?
Most possibly your project still targets the 2.0 runtime.
You'll need to set Project/Settings/Build General/Runtime: Mono / .Net 3.5 in monodevelop.
Don't forget to add the reference to System.Core, if it isn't already added.
