Please can you suggest any implementation of elliptical curve cryptography to be used on .NET platform?
Also if you have used them, can you tell me the recommended curves that should be used?
[EDIT]
As @FatCat mentioned, its implementation is available in .NET framework 3.5 but that is only available on windows vista. Can you please suggest another way/library to use it?

ECC is among the most commonly used implementation techniques for digital signatures in cryptocurrencies. Both Bitcoin and Ethereum apply the Elliptic Curve Digital Signature Algorithm (ECDSA) specifically in signing transactions. However, ECC is not used only in cryptocurrencies.
When it comes to performance at 128-bit security levels, RSA is generally reported to be ten times slower than ECC for private key operations such as signature generation or key management. The performance disparity expands dramatically at 256-bit security levels, where RSA is 50 to 100 times slower.
The foremost benefit of ECC is that it's simply stronger than RSA for key sizes in use today. The typical ECC key size of 256 bits is equivalent to a 3072-bit RSA key and 10,000 times stronger than a 2048-bit RSA key! To stay ahead of an attacker's computing power, RSA keys must get longer.
The .NET Framework already includes Diffie-Hellman, which is an elliptic curve crypto algorithm. Look under System.Security.Cryptography.ECDiffieHellmanCng.
