I am wondering if fsc.exe can support the same please? \n\nThanks \n\nMike \n\nFrom: Kevin Ransom \nSent: Monday, May 23, 2016 3:26 PM\nTo: Mike Lai mikelai@microsoft.com\nCc: Michael Fanning (DEVDIV) Michael.Fanning@microsoft.com; Tomas Matousek Tomas.Matousek@microsoft.com\nSubject: Re: F# Compiler (fsc.exe)\n\nHey Mike,\n\nCan you let me know what this is about?\n\nThanks\n\nKevin\n\nFrom: Mike Lai mikelai@microsoft.com\nDate: Monday, May 23, 2016 at 2:10 PM\nTo: Kevin Ransom Kevin.Ransom@microsoft.com\nCc: \"Michael Fanning (DEVDIV)\" Michael.Fanning@microsoft.com, Tomas Matousek Tomas.Matousek@microsoft.com\nSubject: RE: F# Compiler (fsc.exe) \n\nThanks Tomas for the introduction!
