[Bug] iOS Release Configuration: Linker errors when using Cryptography #14017

Open fhintsch opened 3 years ago

fhintsch commented 3 years ago

Description

Linker issues occur in iOS Release configuration only when using Mailkit, i.e. Cryptography. Error: MT2101, Warnings: MT0109, MSB3276

Steps to Reproduce

  1. VS for Mac, current version: Create a new project by using standard Xamarin Forms template.
  2. Add Nuget package Mailkit 2.11.0.
  3. Create a class "Mail" that uses Mailkit.Security and Mimekit.
  4. Run this project with Platform iOS and Configuration Release

Expected Behavior

The link phase should run without any errors and warnings. If there were warnings, I should be enabled to avoid them.

Actual Behavior

Platform iOS and Configuration Release do not link successful. Error: MT2101, Warnings: MT0109, MSB3276. All other Platform|Configuration combination link successful, although there are warnings.

Confirming that I can repro this issue and see this error:

MTOUCH : error MT2101: Can't resolve the reference 'System.Void System.Security.Cryptography.DSACng::.ctor(System.Security.Cryptography.CngKey)', referenced from the method 'T Internal.Cryptography.Pal.Windows.PkcsPalWindows::GetPrivateKey(System.Security.Cryptography.X509Certificates.X509Certificate2,System.Boolean,System.Boolean)' in 'System.Security.Cryptography.Cng, Version=4.3.3.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

@fhintsch I'm not familiar with the MailKit dependency you're using, but it seems like the issues you're experiencing are related to that dependency and I would try to check with them. If I had to take a guess, I think it could be related to how the password might not be properly secured
