Add-Type error MailKit

Question

I am trying to write a Powershell script that runs MailKit.3.6.0 starting with the command:

Add-Type -Path "C:\Program Files\PackageManagement\NuGet\Packages\MailKit.3.6.0\lib\netstandard2.0\MailKit.dll"

and get the error Add-Type : Unable to load one or more requested types.

Answer 1

Hello there,

Try adding some logging to the CharsetUtils static .ctor to see if that helps narrow things down.

That class basically tries to load a bunch of widely-used text encodings and maps various aliases to them that are commonly used in mail headers. It tries to catch exceptions, but apparently some exceptions make it out.

Hope this resolves your Query !!

Answer 2

My guess is that it's failing to load MimeKit. MimeKit may be failing to load because of its own dependencies, so if MailKit fails to load and the LoaderExceptions points at MimeKit, try loading MimeKit and see why that's failing. Maybe it's BouncyCastle.Crypto that's missing.

try{
    Add-type -path "C:\Program Files\PackageManagement\NuGet\Packages\MailKit.3.6.0\lib\netstandard2.0\mailkit.dll"}
catch{
    $_.Exception.LoaderExceptions 
}
