I'm trying to build an old project with new VS, it throws compile time error:

error FS0452: Quotations cannot contain inline assembly code or pattern matching on arrays

There is a <@@ match x with ... @@> over x (a string, which is a char-array). Is this intended behaviour now?

Expected behavior

Should compile

Actual behavior

Fails
