My Tools: Visual Studio 2010, Crystal Reports 13, MVC3 APP, Windows Azure
When I publish my MVC app in Windows Azure, i get the error: Could not load file or assembly 'log4net' or one of its dependencies. An attempt was made to load a program with an incorrect format.
My SO is 64 bits and server run in 32. I try change my app to deploy on ANY CPU and 32 BITS but does not effect. The assembly that i call is:
<add assembly="log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=692FBEA5521E1304" />
If i remove the assemble and compile, local works fine. But if publish I get the error. Looking in GAC i found two log4net, one in AMD64 and other in 32 Bits. Probably removing the reference on web.config then works local because the .net framework finds in GAC every register that is refered, but then Azure obviously not work.
How publish my 64 bits app in Windows Azure with log4net right to generate the crystal reports?
To fix this erro is necessary check 3 points:
1° How i said in my question, processor (AMD64 or x86) is one of fonts of the erro. Some articles say about change the deploy mode from ANY to x86. This not fix this error, and generate others bugs depending of situation. Dont do this.
2° This LINK show how change the log4net for work. In some cases this can fix the problem.
3° If your processor is correct with version of log4net and the bug persists, install in your server the Crystal Reports CR again, in my case works, perhaps the instalation fix some other bugs in bin folder. In my case, i need to install Azure Cloud app.

I get the "Could not load file or assembly xxx or one of its dependencies*********" error when I host my website on a Windows Server 2012 (IIS 8). The xxx here is my project name in my local VS 2015. The application is working perfectly fine in my local PC
It is a VB.NET application with Oracle 12c database as it's backend.
Things I have tried till now.
1. Publish with setting the Target CPU as "Any CPU" and Configuration as "Release-Any CPU" - Still the same error.
2. In the Server IIS, I have set the Enable 32-but apps as True on App's App pool. This is giving a different error. - Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Please help.
It sounds like your Oracle.DataAccess dll is a 64 bit dll. You can see what driver is loaded on the web server by navigating in Windows Explorer to the \windows\assembly folder.
Most applications that are built with the Any CPU option will have the checkbox in the project settings to prefer 32 bit. To avoid this, change your project's platform target to be a 64 bit.
Then you do not need to "Enable 32 bit" in your application pool and your problem should disappear. Please let me know if this helps.
I am trying to host an application on IIS 7.0, this application is using a third party dll
EFTidynet.dll for removing unwanted html code in the application. when i am running this application using Visual Studio 2010, its working fine, but when i hosted this application on IIS 7.0 its giving the error of
Could not load file or assembly 'EfTidyNet' or one of its dependencies.
I have already added the name in the assemblies section on web.config but still no success.
Can anybody help me out.
EfTidyNet (on codeproject.com) seems to contain only one DLL. The directions say that it needs to be registered in the GAC.
I usually create a folder in my c:\inetpub\ folder named "Bin" or "DLL" or "GAC". It makes it much easier to find registered files (that I'm using for IIS). Microsoft has plenty of good instructions on GACing a file. http://msdn.microsoft.com/en-us/library/dkkx7f79(v=vs.110).aspx
On my development machine, I was having the same error message, followed by:
An attempt was made to load a program with an incorrect format.
Apparently, EfTidyNet is a 32-bit DLL, which didn't work too well on my 64-bit version of Windows 8.
The error disappeared after I enabled 32-bit applications in the advanced settings of the application pool of the web site, as explained here:
Could not load file or assembly exception
I am building ASP.NET application with C# and I want to connect to oracle database.
I have added reference to Oracle.DataAccess in my application on my 64bit Microsoft Window Server 2008 machine.
I also installed ODAC (Oracle Data Access Component) on my machine
and Oracle.DataAccess.dll is also present on this path
C:\Windows\Microsoft.NET\assembly\GAC_64\Oracle.DataAccess
but when i'm trying to connect i encounter following error:
Could not load file or assembly 'Oracle.DataAccess, Version=4.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
As far as I know, the Oracle.DataAccess assembly works only with 32 bits, I also have this kind of problem with 64 bits and it really does not work. My solution was remove the 64bits from GAC and install the 32 bits on GAC. I also remove any .dll file in the bin folder to my application find the assembly on GAC.
There is no problem if your machine and operational system is 64bits, the 32bits version will work fine.
UPDATE
I recommend you take a look at Official Oracle ODP.NET, Managed Driver, that is a better version than Oracle.DataAccess. This Managed Driver does not need the Oracle Client on the machine, and you just need to provide the TNS on the DataSource field of the connection string and it works fine for 32 and 64 bits.
You need to install both x64 and x86 versions of Oracle, because something (I think it was Visual Studio) uses the x86 version when debugging.
In VS2010, I changed the platform target to x64 and this error message disappear.
essentially same error
missing ODP.NET installation components as per last post from me and the other answer participant.
You check the GAC yet?
If you do not see Oracle.xxx folders,
you are not making any headway.
put the correct version and bit of Oracle.DataAccess.dll into the application /BIN folder and make local reference. It solves many problems.
To run your website, you must use IIS since visual studio's development server only runs in 32 bit mode.
In IIS application pool, set your application to run in 64 bit. (The setting is in advanced settings)
To resolve this error, I set my app pool in IIS to allow 32bit applications.
Open up IIS Manager, right click on the app pool, and select Advanced Settings --> set “Enable 32-bit Applications” to True. It's working fine for me.
I got the same exception on a c# console app. What solved it for me is to change the platform target to x86. (project properties => build )
My machine:
Windows XP (x86), VS2008, .net 3.5, sql server 2005, WinForms -> App works fine.
Production Machines: Windows 7 (x64), SQl Server 2005 Express -> App Starts but throws exception
Visual Studio Targeting x86 on setup project and RMO project. Visual Studio gives me a a couple warnings but I can still build:
Unable to find dependency 'MICROSOFT.SQLSERVER.MANAGEMENT.SQLPARSER' (Signature='89845DCD8080CC91' Version='10.0.0.0') of assembly 'Microsoft.SqlServer.Smo.dll'
Unable to find dependency 'MICROSOFT.SQLSERVER.MANAGEMENT.SQLPARSER' (Signature='89845DCD8080CC91' Version='10.0.0.0') of assembly 'Microsoft.SqlServer.Management.SmoMetadataProvider.dll'
This is a simple RMO (Replication Management Objects) app that initiates a pull subscription in SQL Server 2005 and displays status. Works fine on my machine, but fails on the production machine. I'm using a setup project to install the app on the production machine, but I think I'm missing a dependency somewhere, but I can't figure it out.
On the production machine the app starts fine, but when I try to synch the subscription i get:
System.IO.FileNotFoundException: The Specified module could not be found. (Exception from HResult: 0x8007007E)
EDIT: Task Manager in Win 7 inditcates that it is running as a 32-bit app (myapp.exe *32).
EDIT: Ok, my app is now showing in task manager that it is a 64 bit app, but I'm getting an error. I'm thinking that I some how have a dependency dll targeting x86. How can I verify the dependency dll is targeting the correct platfrom and/or make sure that it is targeting x64... I thought the setup prjoect would rebuild the dll in my detected dependencies to target whatever cpu I chose in the setup project?

run Fusion Log viewer as administrator and set it to Log Bind Failures to Disk.
that way you'll be able to see which DLL's don't load properly.

the setup does not compile any dlls for you automatically.

My .NET 2.0 application imports unmanaged 32 bit dll.
The dll is loaded (first interop call happens) when user opens a file via a dialog within the application.
When I deploy the application via clickonce with target platform "Any", users on 64 bit windows get BadImageFormatException when trying to open files from the application (at the moment the unmanaged dll is loaded). I understand this is due to incompabible bitness of the 64 bit process and the 32 bit unmanaged dll.
I have redeployed the application using x86 as target platform. As I understand it, this should solve the bitness problem.
BUT
When I run the deployed application built for x86 on 64 bit system, I now get BadImageFormatException immediately before the application even starts. Tested on at least three 64 bit machines. On 32 bit machines, it works with no problem.
When I run the application directly from VS (or not directly, just a normal build, not going via ClickOnce), there is no problem on 64 bit windows when using x86 target platform. The application starts and user can load file - the interop call succeeds.
I have been debugging this for 2 days straight with no result - I have tried on different computers. It seems to consistentnly work on one of the computers I have tried. However, I do not have permanent access to this computer.
I have managed to build the ClickOnce deployment on my computer once and it worked on a 64 bit machine. This was single of maybe 100 tries! Nothing has changed, the only changed variable was that I did the successful build immediately after computer restart.
I did clean/rebuild/restart VS/restart windows MANY times. I have reinstalled VS 2008 and now also the whole OS, it did not help.
EDIT: I have just managed to get one good build (out of next 100 :)) and did comparison between the deployed directories.
The source of the problem is that ClickOnce generates the wrong target platform in the manifest of the main .exe:
<asmv1:assemblyIdentity name="app.exe" version="1.0.4.18" publicKeyToken=".token here." language="neutral" processorArchitecture="<b>msil</b>" type="win32" />
processorArchitecture should be x86.
So the question is how to consistently force VS to generate the correct processorArchitecture in the manifest when deploying.
Can anyone help please?
This was resolved by installing VS 2008 SP1 on 64 bit Windows 7. VS2008 SP1 on XP had the problem on two machines I have tried with.
I had this problem as well, using VS2008 SP1.
In my case I had a 32 bit DLL which had to be compiled as 32 bit and an application that was using it in the same solution.
Even though I specified X86 as the build target for the release build, when I published a 64bit application was compiled and included in the installer.
I found a slightly brutal solution to the problem:
Go into the configuration manager and remove all possible configurations except the one that you want it to build (Debug and release versions).
After doing this I found that the clickonce installer was generated with the correct application.
I hope this helps someone else, I have been battling this problem on and off for months.
I'd suggest to use Reflector to open the main exe deployed by ClickOnce and see the dependencies to make sure you are not deploying the 64 bit version of the dll by mistake.
You must resolve to run 32-Bit Applications in IIS 7. See http://www.fishofprey.com/2009/04/badimageformatexception-in-iis-70-on-64.html
Sometimes the ClickOnce publishing process seems to cache old files from previous Any CPU or x64 builds. Doing a Clean and Rebuild All didn't fix this problem for me. I needed to delete all of the bin and obj folders from my projects and reopen Visual Studio.
We ran into this problem and determined that the subdirectory of the user profile to which ClickOnce deployed our application must have become corrupted, because we were able to deploy the application successfully with ClickOnce when logged in as a different user on the same machine.
We were able to solve the problem simply by deleting the subdirectory of C:\Users\<user>\AppData\Local\Apps under which ClickOnce was deploying our application. In our case, this was C:\Users\<user>\AppData\Local\Apps\2.0.
