What is going on the deprecated BouncyCastle.Crypto?

The Nuget package is deprecated since a while, when will an update to a new version will come? Because ‘GemBox.Document.35.0.1423, GemBox.Pdf.17.0.1386, GemBox.Presentation.25.0.1504, GemBox.Spreadsheet.49.0.1398’ depend on ‘Portable.BouncyCastle.1.9.0’. That results in conflicts between different versions of “BouncyCastle.Crypto” that could not be resolved.


Unfortunately, no other version of BouncyCastle supports .NET Framework 3.5, which is currently the minimum version of GemBox.Email.

Nevertheless, please try again with this latest NuGet package:

Install-Package GemBox.Email -Version 17.0.1145-hotfix

We have released a new version of GemBox.Email that targets .NET Framework 4.6.1 and has a dependency on Portable.BouncyCastle.

In the future, we hope to replace that dependency with BouncyCastle.Cryptography. But in order to do that, they need to fix this issue.
