'SHA512Managed' is obsolete: 'Derived cryptographic types are obsolete. Use the Create method on the base type instead.'

After upgrading a project to .NET 6, the compiler started to complain with the following warning message:

'SHA512Managed' is obsolete: 'Derived cryptographic types are obsolete. Use the Create method on the base type instead.'

Here is the code that caused this warning:

	var data = Encoding.UTF8.GetBytes("key");
	byte[] hash;
	using (SHA512 sha = new SHA512Managed())
	hash = sha.ComputeHash(data);

The fix was easy:

	var data = Encoding.UTF8.GetBytes("key");
	byte[] hash;
	using (SHA512 sha = SHA512.Create())
	hash = sha.ComputeHash(data);

I don't know why they made this obsolete but the code change got me rid of the warning message.
