FsLex has changed with the latest PowerPack?

Question

I worked on the compiler for a while, but after switching to PowerPack 1.9.9.9 and version version VS2010, I can not compile the following line:

let lexbuf = text Lexing.from_string

I get the following two errors:

"The value, constructor, namespace, or type from_string is not defined" pretty obviopus, what is it trying to tell me, but what is permission?

Answer 1

Lexing.LexBuffer <_>. FromString?

Answer 2

, fromString ( , of_seq, camelCase).
