I am trying to use SQLite with my WPF application. I can get the reads and writes to work ok. The only problem I have is that my xaml is not displaying and I get the following error:
System.BadImageFormatException
Could not load file or assembly 'System.Data.SQLite, Version=1.0.80.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. An attempt was made to load a program with an incorrect format.
My questions:
-How do I know what version of SQLite that I am using? 32bit or 64bit?
-I tried changing the Platform target to x86 and x64 but neither help. How can I resolve this error?
Had same problem when used 64-bit precompiled binaries. Solution is use 32-bit ones instead (manually download them from SQLite site if needed).
A System.BadImageFormatException error often occurs when a 64-bit assembly is opened by a 32-bit application or Conversely. In this case, Visual Studio is a 32-bit application and the Design view is attempting to load a 64-bit assembly. Visual Studio assemblies are located in the project references tree.
Right click on Your Project and select properties item. In Build Tab, change platform target to Any CPU.

I have VS.NET 10.0.40219.1 SP1 in 2 computers and when I create a new C# Winform app only do it with Properties/Build/Platform x86, and the target let me choose AnyCpu/x64, but can't set it in the configuration (however, libraries work fine).
If I try to change it in the project file manually, I get a lot of nasty errors. Is this normal behavior, a bug or a problem in my installation?
P.D: When I change manually the project, this happend:
Warning 1 The OutputPath property is not set for project '*.csproj'.
Please check to make sure that you have specified a valid combination
of Configuration and Platform for this project. Configuration='Debug'
Platform='x86'. This error may also appear if some other project is
trying to follow a project-to-project reference to this project, this
project has been unloaded or is not included in the solution, and the
referencing project does not build using the same or an equivalent
Configuration or
Platform. c:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets
When I reopen the project, ALL the references become invalid
It is normal for Visual Studio to create WinForms projects with just an x86 platform. I have no idea if that's because historically x86 was the only platform type or because x86 is the most commonly used value or for some other reason.
It's also normal to have problems when the project file is manually modified, try to avoid doing that where possible.
To create another platform configuration in a C# project
Select Build | Configuration manager
Select <New...> in the Active Solution Platform field
Select the new type you want
Click on OK
Visual Studio used to create AnyCPU apps by default. I think both VS2005 and VS2008 did this, though they may have changed it for VS2008. Here's what happened: a lot of AnyCPU apps ended up broken on 64-bit systems, because they were built with dependencies on 32-bit libraries. If you tried to run an AnyCPU app that had a 32bit dependancy on a 64bit system, you got a 64bit process that would crash as soon as it tried to load your 32bit dll.
To fix this, the default was changed to use the x86 option. If you want to use AnyCPU, you must now setup the environment for it.
I'm having an issue with the WPF Designer. At some point I did something that broke all of my controls that reference the local assembly. The application builds and runs just fine, but the VS Designer throws errors every time that a local resource is referenced via a clr-namespace.
For instance, I have the following reference:
xmlns:Converters="clr-namespace:MyAssembly.Converters;assembly="
Note that I left off the assembly=MyAssembly because its the local/current.
Then when I reference it in a resources block:
<Converters:IsNotNullConverter x:Key="isNotNull"/>
This was all working up until today. At some point I did something which broke all of the references with the following error:
Undefined CLR Namespace. The 'clr-namespace' URI refers to a namespace 'MyAssembly.Converters' that is not included in the assembly.
I've tried cleaning, rebuilding, restarting VS, closing the designer panes, and all combinations of these 4. It's most likely some other minor issue that is causing the whole thing to blow up (as happens too often in WPF). My problem is that I have no idea how to begin to break this problem down.
Does anyone have any insights or techniques for finding the real issue with this design-time problem? Right now I'm basically going file by file and hoping I can find the needle in the haystack.
Thanks!
"I just solved this by changing the target from x64 to x86. Apparently Visual Studio is 32bit process and it's unable to load 64bit assemblies, and if your assembly is targeting x64 platform and you adding some custom control visual studio is unable to load it and throws this message. "
From: The 'clr-namespace' URI refers to a namespace that is not included in the assembly
I had it set to x64 because of a 3rd party DLL requirement...gonna be tricky. Oh well. Thanks!
I'm trying to compile a simple 32-bit Hello World application written in C using Visual Studio 2010 on a 64-bit machine on a Windows 7 fresh install. I also installed the "Windows SDK for Windows 7 and .NET Framework 4" after installing Visual Studio.
I built the application selecting "Win32" as platform. It works on Windows 7 but if I run the application on my 32-bit machine with Windows XP Professional (fresh install also this, without softwares and Service Packs) it seems not working getting this error:
"This application has failed to start because msvcr100.dll was not found"
If it can be useful Dependency Walker detects 2 errors (see the linked picture for details):
"Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module."
"Error: Modules with different CPU types were found."

How can I solve it? Thanks!
The machine on which it is run needs the runtime libraries. See this MSDN information.
Don't trust Dependency Walker on this... It clearly shows your exe is 32 bit. Your problem is with the VC redistributables, which are the CRT dlls - look for vcredist_x86.exe in your VS installation. You should run it before you run your app.
Another option is to statically link the CRT. See the /MT option. Will make your exe larger, but save the vcredist stuff.
The problem here is the C runtime used by the compiled program is missing on the Windows XP machine. Visual Studio 2010 will by default us the 10.0 (msvcr100.dll) runtime which is not available on XP by default. You need to manually deploy the C runtime on your machine in order for your program to run.
You may want to read the following MSDN article which discusses the issues around deploying C applications built with Visual Studio 2010
http://msdn.microsoft.com/en-us/library/zebw5zk9.aspx
There may be additional 32 / 64 issues at work but this appears to be the primary problem
The answers about the runtime library are correct. Another possible solution is to link to the static runtime libraries rather than to the DLL versions. This way you can build an executable that you can drop onto any machine without extra deployment hassles.
It's a trade-off, but, without knowing more about your situation, it might be worth considering.
I have a project that was created with VS2008. I'm trying to build it with MSBuild 4.0, but still targeting the 3.5 framework. When I do so, I get the exception:
[exec] ResGen : error RG0000: Could not load referenced assembly "C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\PresentationUI\v4.0_4.0.0.0__31bf3856ad364e35\PresentationUI.dll". Caught a BadImageFormatException saying "Could not load file or assembly 'C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\PresentationUI\v4.0_4.0.0.0__31bf3856ad364e35\PresentationUI.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.".
Note that it's trying to load the 4.0 version of PresentationUI.dll, even though I'm compiling for the 3.5 framework. It doesn't matter if I convert the project to VS2010 format or not, the error is the same.
The problem turned out to be that the HintPath of the PresentationUI.dll assembly didn't match the actual assembly location. In that case, MSBuild falls back to looking for the assembly in the GAC. Since MSBuild 4.0 runs on the .NET 4.0 runtime, it picks up the 4.0 version of the assembly, which is incompatible with the 3.5 project being compiled.
I Got the same problem and while looking for the solution in stackoverflow came across this question.Finally after R&D I got the solution.
Remove the old references and add new ones (If any).Go to advanced Compiler option and Select Target Framework as 4.0. :) It worked Enjoy.
One more reason for this Exception is the mismatch of Target Platform among all the Projects in the solution. For example, if a few projects have Target Platform as x86 and the rest have x64 then you will get this exception.
I have an application build on my x64 computer. It is now build for x86 but on windows XP machines (x86) it fails with the "bad image format". On all Vista and up OS, it runs perfectly on x64 platfomrms. I tracked the problem to my icon.
I removed the icon and now it runs fine, anyone got an idea of how on earth this could relate to anything?
This error is basically telling you that a dll being loaded does not match the bitage (32 or 64) of the process. You could be loading up an assembly using native 64bit code, or it could be a single dll that is set to x64. You can use the corflags utility from the Visual Studio Command prompt to check what the .NET assembly bitage is set to.
