I am using Windows Application to communicate with Oracle 11g database to fetch some data. Oracle database was installed on the X64 bit system.
My Application builds successfully on my system (the x86 bit) with x64 bit dlls of Oracle. But when I run application below mentioned errors occurred.
An unhandled exception of type 'System.BadImageFormatException' occurred in your application(E.g. MyApplication.exe)
Additional information: Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.
I had tried different ways to resolve this issue but still unable to found a solution for same. Please help me to resolve this issue.
You are trying to load a 64bit DLL from a 32 bit process or vice versa. Make sure the DLLs you want to load have the same bitness as your process.

I got the error mentioned as below on client machine. For some systems it is working well but for some I get the error mentioned as below:
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
System.TypeInitializationException: The type initializer for 'CrystalDecisions.Shared.SharedUtils' threw an exception. ---> System.BadImageFormatException:
Could not load file or assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies.
An attempt was made to load a program with an incorrect format.
It could be useful to someone: if you have the option to do it, go to IIS and set the Application Pool to 32 bit applications only.
That made the trick for me.
(Of course, your application could be made to run only on 64 bit. In that case, I think the installing of the 64 bit redistributable of CrystalReports should solve the issue)
I am trying to provide a colleague with a dll that is from my build so she can execute with the changes i have made. Unfortunately she gets the following error
The system was unable to launch the requested screen. --->
Unable to display screen.
---> System.IO.FileLoadException: Could not load file or assembly 'file:///name.dll' or one of its dependencies. Operation is not
supported. (Exception from HRESULT: 0x80131515) --->
System.NotSupportedException: An attempt was made to load an assembly
from a network location which would have caused the assembly to be
sandboxed in previous versions of the .NET Framework. This release of
the .NET Framework does not enable CAS policy by default, so this load
may be dangerous. If this load is not intended to sandbox the
assembly, please enable the loadFromRemoteSources switch
Now if she were trying to run it in visual studio i could set the loadFromRemoteSources switch - however this dll is replacing a dll in an install version on a vagrant box. How can i enable the dll to run in this scenario?
Thanks
Been searching for ages, can't find anything helpful. Here is the exception I'm getting:

This applications works fine on the test server but is throwing this exception on the production server. As you can see, the StructureMap code is what is causing the exception.
I had to convert this app to .NET 4 from 4.5 because 4.5 wasn't installed on the production server. After the conversion, the app still works fine on my local machine and the test server.
I have already set the Copy Local to True for the System assembly, but since the referenced version is 4.0.0.0 and not 2.0.5.0, I this made no difference.
Let me know if any more info is needed. Any help you may be able to provide is appreciated.
Make sure your .NET framework is patched. Microsoft released patches to .NET to allow Portable Class Libraries to properly find the appropriate runtime (KB2468871). If you are seeing the above exception (or something like it), it means you're missing the latest .NET framework patches.
Edit the web.config file to remove the reference, which is not required for normal operation:
1 - Open the web.config file in the root of your site
2 - Find the following line and comment it out():xxxxx-is your assembly name.
<add assembly="xxxxx", Version=2.0.5.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
3 - Save and close the web.config file and try again
I found that it was the "await" and "async" that where giving me trouble.
I had Windows XP SP3 with only .NET 4.0, but had to update it to .NET 4.0.3 using KB2600211 - this wasn't updated automatically through Windows Update when .NET 4.0.3 came out because the computer is off-grid.
This is the link to the update:

I just want to share another solution from here that solved the problem on my development machine: installing Silverlight 5 SDK (only 11.2MB at the time of writing this post) was enough to make everything working.
Install Microsoft® Silverlight® 5 SDK from the following link. It resolves and works fine for me.
SDK download
Starting from a machine configuration that only had VS2017 and Silverlight 5 SDK on it, I installed VS2015 on top of that. This is when I started getting the System.Core and System.Windows problems.
When I uninstalled VS2015 and re-installed Silverlight 5 SDK, these problems went away.
My project uses another lib project as reference.
I get this error when trying to run a project in "Relase" Mode, In "Debug" Mode it works fine.
It says that it cannot load the lib project because :
"An unhandled exception of type 'System.BadImageFormatException' occurred in mscorlib.dll
Additional information: Could not load file or assembly 'UserManagementProviders,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.
An attempt was made to load a program with an incorrect format."
BadImageFormatException means 32/64 bit mismatch. Check your project configurations. The x86/x64/Any CPU settings must be messed up among Debug and Release configurations.
I think this is related to the difference in 64bit and 32bit DLL builds and processes.
Try compiling to 32bit by changing project properties/Build/Platform Target.
I'm trying to generate a native image of my .NET 4.0 application using Ngen using a 64-bit Windows 7. When Platform is set to x64 (or Any CPU) - Ngen fails, complaining that 'NGen cannot proceed because Mscorlib.dll does not have a native image.'
When compiling as x86 and using the appropriate Ngen - it works fine. Also, when changing the .NET version to 2.0 - it works. (When trying to Ngen the x64 application with the x86 Ngen, it tells me I should use the 64-bit version.)
More information:
This is (part of) what I see in CMD: The ellipses (= ...) are present in the original.

Mscorlib.dll does not have a native image (Exception from HRESULT:
0x80131F06)
Searching inside C:\Windows\assembly I found 3 mscorlib.dll's. One in GAC_32, one in GAC_64 (both in subfolders beginning with 2.0.0.0) and one in a subfolder temp.
When searching inside C:\Windows\Microsoft.NET I found six of them: two under assembly (in GAC's 32 and 64) both in folders that begin with 'v4.0...', and four in Framework's: 2 in Framework, and two in Framework64 (in each - one in 'v2.0...' and one in 'v4.0...').
Does this mean that only .NET 2.0 mscorlib's are really run as native images (when needed)? And why doesn't Ngen succeed in saving native images of .NET 4.0?
Bottom line: How do I create a native image of a .NET 4.0 application that targets x64?
This is unhealthy. The ngen-ed image of mscorlib.dll should have been created when .NET was installed on your machine. It is located in c:\windows\assembly\NativeImages_v4.0.30319_64\mscorlib\ab0a8fc3d086a3aaf942f366a12a9185\mscorlib.ni.dll. I'm not sure how well the hashed part of the directory name repeats from one machine to another.
You cannot see this file with Windows Explorer, you must use the command prompt. Go check to see if it there, something went seriously wrong when .NET was installed if it is missing. The ".NET Runtime Optimization Service" is the one that gets that job done, make sure you didn't disable it.
A standard mistake is running ngen.exe from a command prompt that isn't elevated.
