System.IO.FileNotFoundException：部署应用程序时无法加载文件或程序集“X”或其依赖项之一

Question

I'm having a strange problem with deploying an application, which references an assembly, written in managed c++.

I've created an assembly X, compiled it and referenced it in an exe file, called Starter.

Starter.exe starts normally on local mashine. However, when I copy ALL contents of the starter debug folder to a virtual mashine, and try to start it there, it crashes with following exception:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or 
assembly 'X' or one of its dependencies. The specified module could not be found.

This does not make any sense to me, because X is right in the same folder as Starter.exe.

What could be causing this problem?

UPDATE

I've examined the dependencies in Reflector on the target machine, and it was able to find files for all of those.

I've also changed the configurations to x86/win32 for all projects.

UPDATE

Here are the logs from Fusion Log (location: C:\\FusionLog\\Default\\Starter.exe\\X, Version=1.0.4538.22813, Culture=neutral, PublicKeyToken=null.HTM):

I cannot sign the assembly, as it references several other assemblies, which are not signed

Answer 1

... Could not load file or assembly 'X' or one of its dependencies ...

Most likely it fails to load another dependency.

you could try to check the dependencies with a dependency walker.

Ie: https://www.dependencywalker.com/

Also check your build configuration (x86 / 64)

Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.

See here: Detected DLLs that are from the internet and "blocked" by CASPOL

Answer 2

I resolved this problem by renaming the DLL. The DLL had been manually renamed when it was uploaded to its shared location (a version number was appended to the file name). Removing the version number from the downloaded file resolved the issue.

Answer 3

I had the same issue. For me it helped to remove the .vs directory in the project folder.

Answer 4

I also had the same issue when I tried to install a Windows service, in my case I managed to resolved the issue by removing blank spaces in the folder path to the service .exe, below is the command worked for me in a command prompt

cd C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319

Press ENTER to change working directory

InstallUtil.exe C:\\MyService\\Release\\ReminderService.exe

Press ENTER

Answer 5

For me, I started the app from within windows explorer (by double clicking on it). Then it crashed immediately.

I then opened Event Viewer of windows and viewed Application and it displayed full stacktrace of error. The stacktrace showed relation with Bitmap or images. It was then turned out to be due to app icon not found

Answer 6

's up guys i read every single forum about this topic i still had problem (occurred trying to project from git)

after 4 hours and a lot of swearing i solved this issue by myself just by changing target framework setting in project properties (right click on project -> properties) -> application and changed target framework from .net core 3.0 to .net 5.0 i hope it will help anybody
