wsdl /sharetypes in Mono 2.8

I'm having an issue using wsdl /sharetypes in Mono 2.8

I always get the following error:

Error: Could not find file "/sharetypes".

When I run wsdl, I also notice that there isn't a sharetypes option:

How can I use /sharetypes?

It looks like the Mono wsdl.exe does not have that option.

Let the .Net one generate your classes and use them.
