How do I use PasswordSalt and MD5 hashing in asp.net formsauthentication- based on a php salt

I'm migrating a vbulletin php application into an asp.net application.  I have passwords that were created using the following code:

$phphashedpassword = md5(md5(password) + salt) ;

now i have an md5 based password and hex driven salt.

How do i authenticate with these parameters using formsauthenticaiton?
the following code doesn't work:

Dim saltAndPwd As String = String.Concat(clearpassword, salt)
hashedpassword = FormsAuthentication.HashPasswordForStoringInConfigFile(saltAndPwd, "md5").ToLower

in my opinion, hashedpassword should be the same as $phphashedpassword.
