ASP.NET 5 Creating RSA key,

Question

I'm trying to create WebApi with token-based authentication in my ASP.NET 5 app. I'm following these steps https://stackoverflow.com/a/29698502/2420851 . But I'm stuck already at the first one with creating RSA key.

Line RSACryptoServiceProvider myRSA = new RSACryptoServiceProvider(2048);

produces compilation error The type 'RSACryptoServiceProvider' exists in both 'System.Security.Cryptography.Csp' and 'System.Security.Cryptography.RSA'

when I add "System.Security.Cryptography.RSA": "4.0.0-beta-22819" to my project.json error message just changes to The type 'RSACryptoServiceProvider' exists in both 'System.Security.Cryptography.RSA' and 'mscorlib'

Namespaces System.Security.Cryptography.RSA and System.Security.Cryptography.Csp are both unavailable.

How can I resolve this?

Do like this:

System.Security.Cryptography.RSACryptoServiceProvider myRSA = new System.Security.Cryptography.RSACryptoServiceProvider(2048);

or you have to remove the colliding imported namespaces and only have the "using System.Security.Cryptography"

If you are using ASP.NET 5 Core then you need to check this question on how to get Crypt to work:

Which encryption algorithm do we use in Asp.net 5 Core

or remove "dnxcore50" from your project.

I have only using System.Security.Cryptography;. Csp and RSA are not availiable... maybe I'm missing some dependency

Did an update of my answer .. does it solve it for you?

No, i tried this before. However I solved the problem. It was about .NET Core, I removed dnxcore50 from project.json and it worked. Thanks anyway

Just found out that myself .. updated my answer accordingly
