mono --aot with MinGW: unknown pseudo-op: `.local'

Question

1. Can I user mono's AOT feature to natively "pre-compile" .NET DLLs (and or EXEs) to make them harder to reverse engineer?

2. If so, how do I get mono/AOT working in Windows 7? (I'm running x64 but the app is targeting x86 explicitly.) I just installed Mono 2.6.3 and MinGW 5.1.6 and I'm trying to AOT compile an exe (or a dll, it doesn't matter).

I get screens and screens of error messages:

C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:533: Error: junk at end of line, first unrecognized character is `H'
C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:539: Error: unknown pseudo-op: `.local'
C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:546: Warning: .size pseudo-op used outside of .def/.endef ignored.
C:\Users\jupdike\AppData\Local\Temp\mono_aot_XSDEAV:546: Error: junk at end of line, first unrecognized character is `H'

I can open the generated assembly code but I have no idea why the assembler chokes on it:

    .size HappyForms_TextForm__ctor_string_string_string_bool,.-HappyForms_TextForm__ctor_string_string_string_bool   (533)

    .byte 16,201,195

    .size HappyForms_TextForm_get_InputValue,.-HappyForms_TextForm_get_InputValue (546)

Answer 1

It doesn't look like this will solve my problem and it also doesn't look like mono AOT is supported on Windows at this time. See this question for more info.
