System.BadImageFormatException: 'Could not load file or assembly 'mongocrypt' or one of its dependencies. The module was expected to contain an assembly manifest.'
I have a project that runs Hangfire 1.7.5 with MongoDB 2.9.1.0. This project is used as a backend engine to perform various types of work.
In order to create endpoints for outside systems to call this engine, we have another project that uses the same versions of Hangfire and MongoDB to connect and pass in the jobs for processing.
I upgraded Hangfire and Mongo to the latest versions, 1.7.9 and 2.10.1.0 respectively in all the projects that were using these dlls. Using Visual Studio, when I run the web projects, I keep getting the above mentioned error. I get these like 4 to 5 times before the ASP.Net site loads up and allows me to access anything I need, including the data that is accessed via MongoDB. Just an inconvenience but still an exception when loading project.
I know that architecture of the CPUs might cause the System.BadImageFormatException but nothing in that sense has been changed. I am running everything on .net 4.6.1 and everything continues to run on AnyCPU configuration. If I change all these projects to x64 or x86, one or the other thing stops working. mongocrypt error continues to occur regardless of the CPU architecture.
I cant find anything on google or SO regarding mongocrypt. Any ideas?
Same thing happened to us.
It appears that in v2.10.0 a new dependency library was introduced libmongocrypt
that causes this error.
Try to go back to v2.9.3 to workaround this issue until it is fixed by mongodb programmers.

Motivation
I'm trying to track down an exception thrown by .NET Framework when opening connection to Access mdb database file. I'm not opening the database connection directly but rather use one of DevExpress Xpo facilities (XpoDefault.GetDataLayer(...) to be precise) which internally attempts to create connection to provided mdb database file. That attempt fails somewhere deep in .NET Framework code and exception is thrown.
Exception has System.Data.OleDb.OleDbException type and is very vague about the problem source. Message says "Unspecified error". ErrorCode is -2147467259 (NativeCode is 0). There is to little information to find out why database connection cannot be created. I thought that maybe going deeper into .NET Framework code would reveal something important about the failure.
Problem
Source files mismatch when stepping into .NET Framework internals. Inconsistent execution flow.
Description
My application is targeting .NET Framework 4.6.1 x86 platform and built in Debug (Release does not change anything). Visual Studio Enterprise 2019 v16.6.3 is the IDE I work with. Of course I've read all I could about debugging into .NET Framework first but it did not help to solve my problem.
What I have done so far? I have successfully download DevExpres PDBs and sources. No problem with that - I can follow execution down into DevExpress internals (which IMHO confirms that overall debugging setup is rather correct). It also seems that .NET Framework PDBs are correctly loaded from Microsoft servers during debugging. I think that Visual Studio Debugging settings are also fine (as far as I'm aware).
All goes well until I need to step into OleDbConnection.cs file which gives the following message:
The problem is that I have all .NET sources available from https://referencesource.microsoft.com. All (including updates) from version 4.5.1 up to latest 4.8.
No matter which one I choose - I'm always getting same message about not matching source file version. When I ignore the message and decide to use the source file anyway, it shortly turns out that inconsistency is real. Instead of tracking the source code execution I'm stepping over comments or execution flow simply does not make sense and clearly the presented source code is not in sync with what is going on.
Ok, that's it. I could not get any farther. Am I doing something wrong? Where to look for .NET Framework sources which would match the executing modules and allow to discover origins of the exception I'm getting?
Update #tgolisch
Code which gives an exception:
Session Session;
ReflectionDictionary reflectionDictionary;
string connectionString;
...
Session = new Session(XpoDefault.GetDataLayer(connectionString, reflectionDictionary, AutoCreateOption.SchemaOnly));
Connection string used in XpoDefault.GetDataLayer(...) call:
"Provider=Microsoft.Jet.OLEDB.4.0;Password=;User ID=Admin;Data Source=C:\\Svn\\trunk\\Apps\\bin\\Debug\\DbFile.mdb;Mode=Share Deny None;"
XopDefault.GetDataLayer(...) is the call which fails and throws exception.
Update #Perry Qian-MSFT
I did exactly what you suggested with no success. There was no improvement at all. However, I have made a fair progress after disabling optimizations of system assemblies as described here. With optimization turned off, tracking of .NET Framework internals becomes feasible. No more random jumping or stepping over comment lines.
However, it is not a full success yet, because I'm still getting messages about mismatch between executing modules and the source code file versions.
I have also noticed that even though my app has .NET Framework 4.6.1 as a target it still uses version 4.8 of system modules during execution:
That suggests I should use .NET Framework 4.8 sources when stepping into framework internals. But wait - I have tried all sources I could get with the same mismatch problem.
What can also be seen is that there is more than one version of system assemblies being run with the app - 4.8.4110.0 and 4.8.3761.0, which suggests that different sources might have been used to build them.
Yet still, no matter which sources I take there is always a message about source mismatch at some point.
Considering that assembly optimization problem has been resolved, which framework sources should I use now to have them in sync with running modules?
Source files mismatch when stepping into .NET Framework code
Please reconnect your DB Access database to refresh your database in case there are some build errors in the db layer.
Besides, please follow these suggestions to troubleshoot your strange issue:
1) Tools-->Import and Export Settings-->Reset all settings-->..General to reset all debugging settings.
2) then, close VS, delete .vs hidden folder under solution folder, bin and obj folder.
I'm looking at incorporating the new Google Apps Script Execution API into an existing C# plugin i have already working. I am following the .NET quickstart guide provided as a console application (which i have gotten working without problem).
When porting the code from that into my plugin it will also fail at runtime at the first instance of:
UserCredential credential;
which I slimmed down the code so far to just that line which fails giving:
"Could not load file or assembly 'Google.Apis.Auth, Version=1.9.2.27817, Culture=neutral, PublicKeyToken=4b01fa6e34db77ab' or one of its dependencies. The system cannot find the file specified."
The file is properly referenced (having installed via nuget).
C# is not my normal field and perhaps i'm missing something in the subtlety of it working in a Console App.
What gives?
There was a time when console apps defaulted to using the client profile rather than the full .Net framework. Check the properties of the project on the Application tab and make sure the target framework doesn't end with Client profile. If that doesn't work try using the fusion log viewer, which you'll find conviently located at C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin, or any number of other places. Run it as an admin and it'll tell you what it can't load (which may or may not be Google.Apis.Auth) and where it looked for the file at.
This has been a little bit of a red herring. Not very well documented is the fact for the app i am building against, Autodesk Navisworks,
plugin dependency libraries have to be duplicated in a separate directory altogether from the plugins directory.
Easily fixed for the build environment, but will need a little more thought for when creating a distributable.
Ok this question is more about understanding what the issues are as I dont think anyone will be able to tell me how to fix the problem.
I am writing a .net 4 application and I have a 3rd party dll ( hasp dongle protection ) that I want to reference.
Visual studio allows me to create the reference fine and use classes contained within the dll within my code.
The first issue occurs when the program is run and the dll is actually loaded. I then get the following error.
System.BadImageFormatException: Could not load file or assembly
'hasp_net_windows.dll' or one of its dependencies. is not a valid
Win32 application
This weblink states how to fix this error. Coud someone expalain what the issue is and why im getting it.
After following this advice I then set the main project build to x86 and I then get another error replacing the other. The new error is:
System.IO.FileLoadException: Mixed mode assembly is built against
version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0
runtime without additional configuration information
This weblink states how to fix the error, but I dont have an app.config in my project and want to avoid having one if at all possible. If someone could explain what the issue is again that would be helpful?
Please let me know if you require anymore information.
The issue is the "bitness" of your application. Once chosen (32 bit or 64 bit) all DLLs within that process need to be the same. This exception tells me that one of your DLLs is the wrong "bitness".
You simply cannot have DLLs with different compilation targets within a given process, a process has "bitness" affinity.
If this is a third party unmanaged DLL then it is very likely 32-bit compiled.
Setting the build output as x86 for the root project (the one that creates the exe) should suffice as this will dictate the process that is created. Any other .NET projects can then simply be Any CPU and will fit in either the 32 or 64 bit runtimes.
Unfortunately for your second issue, the provided link is the way to solve it. There is nothing wrong with having an app.config in a project and you haven't stated why you don't want one.
The answer by Adam Houldsworth notwithstanding, I'd like to add that it is possible to do it without an app.config. However, this requires a tiny bit more work and potentially a proper understanding of COM interop. Whether it's worth the trouble is up to you of course ;).
You can set useLegacyV2RuntimeActivationPolicy programmatically by using the ICLRRuntimeInfo::BindAsLegacyV2Runtime method.
A quick rundown on how to do this is posted in this blogpost. Take note of his warning though, which might make you think twice in using this approach:
This approach works, but I would be very hesitant to use it in public
facing production code, especially for anything other than
initializing your own application. While this should work in a
library, using it has a very nasty side effect: you change the runtime
policy of the executing application in a way that is very hidden and
non-obvious.
I cannot use an app.config file because the assembly is loaded via COM from a native program.
I found the library that supports .net framework 4.0. here. In this scenario, no other solutions had worked for me.
I ran into a weird issue today while debugging one of my projects. I use VS2010 / windows 7 home premium.
I have a project that uses Windows Server AppFabric Cache. I have configured everything, and have created two different C# projects (2 solutions) to test the AppFabric configuration. The project names are "AppFabricServer" and "AppFabricClient". This is just for testing and the naming convention doesn't mean anything specific. I use "AppFabricServer" to Add objects to AppFabric Cache and "AppFabricClient" project to retrieve.
Now, the problem is after running the "AppFabricServer" and then I try to run "AppFabricClient" after closing the "AppFabricServer", I get an error "System.IO.FileNotFoundException: Could not load file or assembly 'AppFabricServer". I don't understand in which way "AppFabricServer" project is related to "AppFabricClient" project.
The same thing happens vice-verse also - this means, after restarting the computer and if I run "AppFabricClient" project first (it also has a Cache writing module), I am not able to run "AppFabricServer" project (it has a Cache reading module as well). I get the same error -"System.IO.FileNotFoundException: Could not load file or assembly 'AppFabricClient".
The exception is thrown at the line where I try to retrieve data from the Cache - when I call the Get method of DataCache.
Can someone please help?
AppFabric utilizes the NetDataContractSerializer to serialize objects. This serializer encodes CLR type information. So, even if the shape of your objects is the same, it actually requires them to be the same types in the same assembly.
Therefore, take the object you are serializing out of the AppFabricServer assembly and put it in a third assembly that is referenced from both the AppFabricServer and AppFabricClient programs. That way, the CLR type information will be the same in both.
I'm trying to port some ASP.Net code to mono. I am testing it using xsp2. I compile it with Visual Studio also before running it with xsp2.
Whenever I go to a practically blank page in my application I get
Parser Error Message: Assembly ADODB, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A not found
I have searched and not found any info anywhere about this. I know the web application makes use of Webparts and the SqlPersonalization thing which is not supported in Mono, but I'm going to basically a blank page with a master page and getting this strange error.
And I have ran Moma and it only complained about web parts and SqlPersonalization, neither of which are on the page I'm trying to view(or referenced in any way).
What could be the problem here? Has someone hit a problem like this before? Also I'm using the latest version of Mono on Windows
ADODB is the primary interop assembly for the old Microsoft ActiveX Data Objects (ADO, aka MDAC) COM-based database access layer. Looks like the ASP.NET code you're trying to port uses an older, non-.NET data access library for some reason. I suspect that library doesn't, and never will, exist on Mono.
One solution would be to port the code that uses ADO to ADO.NET, if that's possible.
