I am using the setup from sqlite.org:
http://system.data.sqlite.org/downloads/1.0.94.0/sqlite-netFx451-setup-bundle-x64-2013-1.0.94.0.exe
Setups for 64-bit Windows (.NET Framework 4.5.1)
My application is set up to use framework 4.5.1.
"Prefer 32 bit" is not checked.
During Debug Mode, it runs flawlessly.
However, when I switch to Release Mode, I am getting this error:
"BindingFailure" detected at "D:\Dev\Projects\MyProject\AppNet\MyApp\MyApp\Release\MyApp.vshost.exe"" festgestellt.
The assembly "System.Data.SQLite" could not be loaded in AppDomain1 in the binding context of "Load":
System.BadImageFormatException: The file or assembly "System.Data.SQLite, Version=1.0.94.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139" or one of its dependencies was not found.
Can somebody tell me how I should do differently?
It seems that my question is a duplicate of
Could not load file or assembly 'System.Data.SQLite'
In this post, there was no real answer but just the suggestion to use x86.
However, I think that this is only a workaround, not a real solution, because the SQLITE binaries are clearly marked 32bit and 64 bit, and I have chose then correct assemblies.

I am having a strange problem since installing the latest version of ODAC, 11.2.0.2.1. I installed both the 32-bit and 64-bit versions because I develop applications for both architectures. My computer is Win 7 64-bit.
Since installing ODAC and referencing the new 64-bit version of ODP.NET, one of my web application projects in Visual Studio 2010 gives the following warning for all aspx pages and masterpages when I view them in Markup View.
ASP.NET runtime 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.
The warning is limited to Markup View. The web application builds and runs fine. I tried cleaning the VS Temporary ASP.NET Files, but that did not fix the issue. I removed all references to Oracle.DataAccess throughout my application, and then readded them to be sure that all the references were correct. The web app is compiled to 'Any CPU' but it uses the 64-bit Oracle.DataAccess. I created a new project, and referenced the same projects and dlls, and I do not get the warning, so it appears to be specific to this project file.
Any ideas why I would get the warning when in Markup View?
Expressly set the "Platform target" to "x86" or "x64" in the project properties --> Build tab.
Do NOT set it to "Any CPU." This is one of many common conditions which causes this driver of typical Oracle software quality to have a nervous breakdown.
Turns out the ODAC 11.2.0.2 xcopy installer doesn't correctly register all of the dlls (See bottom answer). As a result, Oracle.DataAccess.dll (64bit) was being copied into the BIN directory, and VS was trying to load it when in Markup View causing the warning. After manually registering the missing DLLs and rebooting, I am no longer having the problem.
Ideas you can check:
Check the Oracle.DataAccess reference in your Visual Studio project has the 'Specific Version' property set to 'False' (this is not the default).
Use the Fuslogvw.exe to determine what are the locations the .NET Framework is trying
my scenario is the following (Win7, VS2010, .NET 4.0):
I have a .NET assembly from an external company compiled for "Any CPU" (verified with corflags.exe). This assembly loads a native dll also from the external company. This native dll exists in two versions - x86 and x64. I have both available.
When I create a console application, add the .NET assembly (while making sure one of the native DLLs can be found by the .NET assembly), create an instance of one of the classes from that .NET library and start the program everything is fine.
However when I follow the exact same steps within a WCF Service, I am getting a BadImageFormatException. Now the obvious thing is search for the error in the targeted platform (I tried "Any CPU", "x86", "x64") or trying to exchange the native DLL (I tried both x86 and x64), but that does not help. I tried all combinations btw...
Does anyone have an idea what the problem might be?

P.S.: I read BadImageFormatException encountered with WcfSvcHost and IIS WCF host and as the author states he solved a similar problem by corflagging WcfSvcHost.exe as 32BIT, but WcfSvcHost.exe is strong named so I can't resign it. Not sure how he got it to work...
You could drop the dependency on WcfSvcHost, and host/debug the service in a local IIS where you can explicitly set the AppPool to either 32 or 64 bit. That's what I'd do.
I have a project that works great on my machine (and production servers).
It's a VS2010 project running C#3.5.
When letting my build server build the solution it can't resolve a couple of my third party dll's.
Error message:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets(1360,9):

retarget your application to a

Version=8.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a".
[d:\Builds\3\mySolution.sln]
Everything compiles and runs great on my machine, but the build server seem to struggle.
I think the Third.Party.Assembly is written in VB.net.
Since the assembly is third party I can't remove the reference to "Microsoft.VisualBasic.Compatibility" and since I don't get any warnings on my computer could it really be that I'm running v3.5?
Any suggestions?

If you put your project on the build server manually will it run? Based on the error message, I would make sure you have the latest .net framework installed on the build server machine and give it another try. If that does not work try installing VS2010 on the build server just to get the builds running until you find out just exactly what assemblies you are missing.
So, I was having this issue also on a VS2005 project that we upconverted... The issue is that MS has never had a 64-bit version of the VisualStudio.Compatability DLL. Our issue was that we were targeting 'Any' CPU and building on a new W2008R2 server so it was using the 64-bit version of the .NET 4.0 Multi-targeting pack.
In the build properties under the 'Process' tab under the '3. Advanced' there is a 'MSBuild Platform'. Change that value to "X86" and it might work... assuming of course you aren't depending on any 64-bit libs...
I'm trying to add a .NET 4.0 .dll to the GAC. I am attempting to do this because it is published by a 3rd party company as both a 32 and 64bit .dll which I must use from different apps on different platforms in both formats.
At any rate, I am having trouble registering this dll to the GAC on a Windows Server 2008 environment.
I have tried copying gacutil.exe (and supporting file) found at "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools" on my local machine to the "C:\Windows\Microsoft.NET\Framework\v4.0.30319" folder on the target production server per the suggestions found here.
I then tried copying them to "C:\Windows\Microsoft.NET\Framework64\v4.0.30319".
Running from both locations indicated successful installation. And indeed, the registration appears successful:
C:\Windows\Microsoft.NET\assembly\GAC_64\ChilkatDotNet4\v4.0_9.0.8.0__eb5fc1fc52ef09bd\ChilkatDotNet4.dll
C:\Windows\Microsoft.NET\assembly\GAC_32\ChilkatDotNet4\v4.0_9.0.8.0__eb5fc1fc52ef09bd\ChilkatDotNet4.dll
However, running a console app that refers to the (64bit) version of the dll errors out with the following message:
System.IO.FileNotFoundException: Could
not load file or assembly
'ChilkatDotNet4.dll' or one of its
dependencies. The specified module
could not be found. File name:
'ChilkatDotNet4.dll'
So, I have now manually created the following GAC entries using mkdir and copy from a command prompt (which may or may not actually work. I have no clue what is so special about gacutil.exe):
C:\Windows\Microsoft.NET\assembly\GAC_MSIL\ChilkatDotNet4\v4.0_9.0.8.0__eb5fc1fc52ef09bd\ChilkatDotNet4.dll (using the 64bit version of the dll)
C:\Windows\assembly\GAC_64\ChilkatDotNet4\v4.0_9.0.8.0__eb5fc1fc52ef09bd\ChilkatDotNet4.dll
C:\Windows\assembly\GAC_32\ChilkatDotNet4\v4.0_9.0.8.0__eb5fc1fc52ef09bd\ChilkatDotNet4.dll
After each "install" of the dll, I tested and received the same error. Any ideas welcome!
EDIT: the GAC issue above may not actually be the culprit. Turns out, even when I create a brand new Console App project and add the .dll directly (so that it lives in the bin), I still can't run it on the sever. Also, I've noted that Console apps are created targeting the .NET 4.0 Client Profile rather than the .NET Framework 4. When I try to run it targeting the client profile, it appears that none of the System.Web* libraries are available. However, I tried running a very simple test app targeting both and neither would run on the server while referencing the bad .dll.
Is there a special kind of install that was to occur to run .NET 4.0 Console Apps?
For anyone else who may have trouble with this in the future. It was not a generalized problem with the way I was registering the dll to the GAC or how I was referring to it from my projects.
ChilkatDotNet4.dll (and the other versions I'm sure) was built in Visual C++. So, the server it is being deployed to has to have the Visual C++ Runtime installed for the appropriate processor architecture.
For 2010 (.NET 4.0):
x86
x64
If you're running an x86 app on a 64-bit platform. Make sure to mark the application pool with "Enable 32-bit applications" = true.
I am trying to add a VC6 COM DLL to our VS2010RC C# solution. The DLL was compiled with the VC6 tools to create an x86 version and was compiled with the VC7 Cross-platform tools to generate a VC7 DLL.
The x86 version of the assembly works fine as long as the consuming C# project's platform is set to x86. It doesn't matter whether the x64 or the x86 version of the DLL is actually registered. It works with both. If the platform is set to 'Any CPU' I receive a BadImageFormatException on the load of the Interop.<name>.dll.
As for the x64 version, I cannot even get the project to build. I receive the tlbimp error:
TlbImp : error TI0000: A single valid machine type compatible with the
input type library must be specified.
Has anyone seen this issue?
EDIT:
I've done a lot more digging into this issue and think this may be a Visual Studio bug. I have a clean solution. I bring in my COM assembly with language agnostic 'Any CPU' selected. The process architecture of the resulting Interop DLL is x86 rather than MSIL.
May have to make the Interop by hand for now to get this to work.
If anyone has another suggestion let me know.
This issue can be resolved by opening the CSProj file and adding the following node to any of the '(Configuration)|Any CPU' nodes that are missing it:
<PlatformTarget>AnyCPU</PlatformTarget>
If this node is not present TlbImp will default to x86 and cause issues.
