Nuget Package (net5.0) is missing portable.BouncyCastle dependency about dgcreader

Thanks @FrancescoBonizzi and @Mrizzi-96 for the informations, I will look into this problem as soon as I can

Hi @Mrizzi-96 , thank you for reporting this problem.

The library does not need a dependency to BouncyCastle when targeting .NET (5 or greater), because for recent version of .NET it uses the apis under the System.Security.Cryptography namespace instead.

If you are targeting .NET5 you should be able to remove this dependency. Can you tell me something more about your project and what error did you get without this dependency?

I have a similiar issue: I wrapped your library in a .NET Standard 2.0 library, but I reference it in a .NET 6 console application, and it throws this exception:

Validation failed with error Could not load file or assembly 'BouncyCastle.Crypto, Version=1.9.0.0, Culture=neutral, PublicKeyToken=0e99375e54769942'. The system cannot find the file specified. System.IO.FileNotFoundException: Could not load file or assembly 'BouncyCastle.Crypto, Version=1.9.0.0, Culture=neutral, PublicKeyToken=0e99375e54769942'. The system cannot find the file specified.

Note two things:

• I fixed in the same way as the developer that posted the issue
• I read this exception because I implemented all loggers, but the output is Cerificate not valid. Maybe it could be helpful to make the Exception exit from the Verify method?

Thank you @FrancescoBonizzi , I will investigate this behavior as soon as possible.
Can you give me some details about how dependencies are configured in your projects?
Are you referencing the library this way:

└─ Application project (.net 6)
    └─ Class Library (.netstandard2.0)
        └─ DgcReader libraries

or this way:

└─ Application project (.net 6)
    ├─ DgcReader libraries
    └─ Class Library (.netstandard2.0)
        └─ DgcReader libraries

Thanks a lot!

Like this:

If I am not wrong it is the first choice you wrote!

Hi @DevTrevi , @FrancescoBonizzi,
The error I mentioned is the same one that @FrancescoBonizzi had. The difference lies in the fact that my project is fully written in .NET 5.0, and does not reference other projects written in .NET standard 2.0.
Henceforth, my file structure looks like this:

The library in the red square was added manually.
Hope this helps!
