Welcome to the MongoDB user community! We understand that you are attempting to build and run a .NET application using the MongoDB .NET/C# Driver v2.14.1 but are receiving the following error when you enable snappy or zstd compression:
Unable to load shared library ‘libdl’ or one of its dependencies
The driver implements snappy and zstd compression using unmanaged compression libraries, which are dynamically loaded using the dynamic loader libdl.so. This error indicates that the CLR cannot find libdl.so in the Docker image. libdl.so is part of the Linux operating system, though is sometimes stripped out of minimal images. The .NET 6.0 devcontainer likely has libdl.so included whereas the production image does not. You’ll have to modify your Dockerfile to include the appropriate package that contains libdl.so.
