No, the VS debugger doesn't have a way to show return values (apart from possibly stepping down to JIT'd x86 code and looking at machine registers); this is problematic for every language, but perhaps moreso for F#.

Possible workarounds:

- use the immediate window to (re-)evaluate the last expression (with C# syntax, the immediate window doesn't know F#)

- step out of the function and inspect the value if it was assigned to a local binding in the caller

- modify the code to end with e.g. "let r = ...; r" so that the return value has a name that can be inspected in Debug mode
