Using OAuth 2.0 for Server to Server Applications

The examples provided are for java and Python. I would like an example for VB.NET. I am particularly interested in the JSON Web signature piece.

"Sign the UTF-8 representation of the input using SHA256withRSA (also known as RSASSA-PKCS1-V1_5-SIGN with the SHA-256 hash function) with the private key obtained from the Google Developers Console. The output will be a byte array."

Can this be done in VB.NET?
