C# password salt information

I have an existing VBA application which makes use of borrowed code to generate a random salt of a preset length and Base64 encoding. Now that I am beginning with C# using Visual Studio I need to be able to do the same operations for login to my database except rebuild in C#. My VBA stored the salt and the salted password and user name in the database back end. On the front end I take the password supplied by the user run the SHA512 hash with the stored salt and see that the hashed salted password matches the stored salted password. I am looking for the code or library to be able do all of this in C#.

Thank you.

Easy... just google C# SHA512 and there's plenty of links that come up that should help.
