Have a look onto Crypt::CBC source, particularly onto _generate_iv_and_cipher_from_datastream and _salted_key_and_iv functions. Crypt::CBC doesn't read IV from encrypted data, it computes IV from the salt and passphrase. Note, that C# implementation may use another algorithm to compute encryption key from the salt and passphrase.
