System.DllNotFoundException: Unable to load shared library 'Magick.Native-Q8-x64.dll' or one of its dependencies.

[Manish082007]

I am not able to resize images using Magick.Net on Debian 11. It is working fine on windows. I am using Amazon ECS Services and deploying a docker image on ECS Service. I am using Magick.NET-Q8-AnyCPU library file version 12.2.1.

Let me know if i am missing anything or doing something wrong.
Your help is highly appreciated. I tried many other libraries too but no success.
I have not been able to resize simple images using Asp.Net core application on Linux for the last 3 days.
THANK YOU...

Already doing

1. I am already adding below tags in csproj PropertyGroup

<MagickCopyNativeLinux>true</MagickCopyNativeLinux>
<MagickCopyNativeLinuxMusl>true</MagickCopyNativeLinuxMusl>
<ErrorOnDuplicatePublishOutputFiles>false</ErrorOnDuplicatePublishOutputFiles>

2. I am renaming Magick.NET-Q8-x64.Native.dll.so from runtimes/linux-x64/native folder to libMagick.NET-Q8-x64.Native.dll.so and copying to bin\Debug\net6.0 folder.

3. Adding Below code in docker file too

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        fontconfig \
        libopenjp2-7 \
        libfontconfig1 \
    && rm -rf /var/lib/apt/lists/*

What is the output of ldd Magick.NET-Q8-x64.Native.dll.so?

[Manish082007]

@dlemstra - instead of renaming dll file to libMagick.NET-Q8-x64.Native.dll.so, I renamed it to libMagick.NET-Q8-x64.Native.dll. Now it able to find load the DLL.
...
But right now, I am getting error ImageCorrupt error. By looking some of issues from GitHub, i came to know there is no issue with Magick.Net library. I am using Aws Api Gateway with multipart content type. So i need to play with some configuration. I will keep you posted with finding.
...
Thank you

@dlemstra - I am able to resolve this issue. The problem was Aws Api Gateway was converting base64 string. I just need to specify the multipart-data as binary type & re-deploy the API stage. Thank you for all your help.
