    if it is an online instance (meaning you can only register the assembly in sandbox) the alternatives are two:

    1) try to merge the assemblies with ILMERGE (there are guides to do this for dynamics plugins as you need to keep consistent the signing)

    2) create a public reachable webservice to perform the action and inside your plugin you call the webservice and return the results

    I don't think you can use any external libraries with plugins. You can use ILMerge and merge them in but you loose Microsoft support as they are not going to touch your solution if you have used ILMerge by my experience.

    Another approach is to create a HTTPS service that can offload the logic. We use Azure Functions and establish a secure connection where the Azure Function query the external resource with the external library.

    Hope this helps.
