.NET implementation of scrypt

I've read about scrypt and some of its advantages over the bcrypt hashing algorithm in certain circumstances. Anyhow, it seems scrypt isn't as widely used yet. Has anyone seen so far a .NET implementation of it (favored in C#)?

Can I improve the security of MD5 hashed passwords by salting the existing MD5 hash and hash the result using Scrypt or PBKDF2 HMACSHA256?

I have a database of legacy passwords that were salted and hashed using MD5. I would like to update the system so that the data is more secure. The first option is to transition the users to a new hashing scheme (Salt + Scrypt or PBKDF2 HMACSHA256)…

Specifically this. I know most bcrypt implementations are around 50 characters for, but I'm pretty certain that's not the case with scrypt.
