I have a project in c# that uses c++ library and some dlls. When I run it it works great.
The library is Awesomium, contains both c++ library and c# wrappers
When I create reference to this project from my ASP.NET MVC 4 project I get the following error:
Exception Details: System.BadImageFormatException: Could not load file or assembly ‘file:///D:ProjectsDevelopmentProGamersGamingSitebinavcodec-52.dll’ or one of its dependencies. The module was expected to contain an assembly manifest.
Things I’ve tried:
-
Coping the dlls, but it still doesn’t work (The file exists).
-
Registering it in the GAC but I’ve got the same error there.
-
Make sure using .NET Framework 4.0 (and not client profile)
-
2 files with the same dll/exe name causing conflict — I dont have it.
-
Change the platform of the solution to AnyCPU/Mixed Platforms.

Question

Hi, I can get started debugging my application.
When I hit «Run» I’ll get error message «Error while trying to run project: Could not load file or assembly ‘CANopenConf’ or one of it dependecies. The module was expected to contain an assembly manifest
But when I look in my debug folder, all needed dll’s are there, and if I start the application by double clicking in Explorer, all works fine.
what is wrong?
thanks in advance, Patrik

Can you tell us some more details on your application type? Does your solution contain C++ or C# or VB projects? Are you sure that you have set the correct project to be the startup project?

An assembly manifest contains all the metadata needed to specify the assembly’s version requirements and security identity, and all metadata needed to define the scope of the assembly and resolve references to resources and classes. The assembly manifest can be stored in either a PE file (an .exe or .
Can not load file or assembly?
In summary if you get the «Could not load file or assembly error», this means that either your projects or their references were built with a reference to a specific version of an assembly which is missing from your bin directory or GAC.
I found that, I am using a different InstallUtil from my target .NET Framework. I am building a .NET Framework 4.5, meanwhile the error occured if I am using the .NET Framework 2.0 release. Having use the right InstallUtil for my target .NET Framework, solved this problem!
BadImageFormatException, in my experience, is almost always to do with x86 versus x64 compiled assemblies. It sounds like your C++ assembly is compiled for x86 and you are running on an x64 process. Is that correct?
Instead of using AnyCPU/Mixed as the platform. Try to manually set it to x86 and see if it will run after that.
